Intel Tri-Gate Transistors Will Fuel Mobile Push vs. ARM

Intel’s new 3D transistors, which will appear first in the upcoming “Ivy Bridge” processors, will help drive the vendor’s mobile efforts, but will they be enough to dislodge ARM?

Intel’s new transistor technology will enable the giant chip maker to continue extending Moore’s Law in PCs and servers for at least the next few years, but it’s the possible impact on the company’s mobile ambitions that will draw the most interest from industry observers.

Intel officials on May 4 introduced the new three-dimensional transistor technology they called Tri-Gate, which essentially moves away from the flat “planar” circuitry of previous designs and to a three-dimensional structure. The Tri-Gate transistors will appear in Intel’s upcoming “Ivy Bridge” processors, the 22-nanometer shrink of the current “Sandy Bridge” microarchitecture.

The Tri-Gate design enable the Ivy Bridge processors to offers higher levels of performance while driving down electrical leakage and power consumption, all in a package smaller than the current 32-nm chip design, according to the officials. Bill Holt, senior vice president and general manager of Intel’s Technology Manufacturing Group, likened the idea behind the Tri-Gate design to that of a skyscraper.

“Clearly you can pack anything in the same space if you go up and not just sideways,” Holt said during a press conference in San Francisco that was also Webcast.

The numbers are impressive: 37 percent better performance than current 32-nm chips and 50 percent power reduction Ivy Bridge chips will begin sampling later this year, and begin appearing in PCs and servers in early 2012, officials said. They later will begin moving into other devices—including tablets and smartphones—at a later date. The officials would not be more specific.

David “Dadi” Perlmutter, executive vice president and general manager of the Intel Architecture Group, said during the press conference that not only will the new transistor design keep Intel “extra-competitive” in the company’s core server and PC market—where Intel controls more than 80 percent of the market—but also enable it to move even deeper into the smartphone and tablet spaces, which are dominated by processors built on designs from ARM Holdings.

Those are areas that Intel executives in which executives said they expect to be major players, thanks to their Atom chip platform.

“The fact that x86 products will have first access to 3D transistor gate technology will likely help offset to the architecture handicap of x86 vs. ARM in optimizing low-power,” Doug Freedman, an analyst with Gleacher & Co., said in a research note. “We do not view this as game changing, but do see it as heating up the x86 versus ARM battle.”

Roger Kay, principle analyst with Endpoint Technologies Associates, said it makes sense that Intel will make a significant push into the tablet space with the 22-nm Ivy Bridge chips, but that he wouldn’t expect the company to make its mark in smartphones until it starts coming out with its 14-nm chips—featuring the Tri-Gate technology—about two years later. It won’t be until that time that Intel processors will be able to challenge ARM in low-power capabilities, Kay said.

“Not at 32, maybe at 22, for sure at 14,” he said in an interview with eWEEK. “Maybe 22 is not all the way there for handsets yet, while it’s plenty for the tablet business.”

Both Kay and Rob Enderle, principle analyst with The Enderle Group, said Intel also is facing a market situation from an unfamiliar vantage point. Intel for years has been the dominant player in the PC and server chip space, giving it an advantage similar to that of a political incumbent. Now, however, it’s the upstart company trying to displace the top vendor—ARM—in the mobile device space.

“There is still a lot of inertia holding ARM in place,” Kay said.

That inertia will be difficult for Intel to displace, even with the kind of resources it has.

“Intel is coming at this market from behind, but the investment is almost unparalleled in the history of the company and yet it still might not be enough,” Enderle said in an email. “The difficulty is they have to not only be better, they have to be enough better to displace a very different technology. Generally, Intel has benefited from this dynamic as the entrenched vendor in the PC space; now this market dynamic works against them. Making a massive improvement like this [new transistor structure] will be critical to this battle, but it will still require them to walk away with major wins, and is this is enough to move, even with major Intel co-funding, a major vendor to their product set?”

Over the past week, there has been speculation that Intel is looking to serve as Apple’s foundry for ARM-based chips for such popular mobile devices as iPhones, iPads and iPods. The rumors were fueled by a research note from Piper Jaffray analyst Gus Richard, who said that “based on a number of inputs, we believe Intel is also vying for Apple's foundry business. It makes strategic sense for both companies. The combination of Apple's growing demand and market share in smart phones and tablets gives Intel a position in these markets and drives the logic volume Intel needs to stay ahead in manufacturing.”

Such a deal would be critical for Intel, Enderle said.

“Rumor is that Apple is looking at such a move, and if they get Apple, the earth moves,” he wrote. “But if they don’t get a major brand and/or a very popular product, [the Tri-Gate technology] still won’t be enough.”

Intel is not sitting still waiting for the Ivy Bridge chips. The company last month officially announced its Atom Z670 “Oak Trail” processor designed for tablets, with officials saying they expect at least 35 designs powered by the chip to start hitting the market this month. They also have said they expect Intel-powered smartphones to be released beginning later this year.

Along with helping drive Intel’s mobile ambitions, the Ivy Bridge chips will help counter efforts by ARM and its partners, including Marvell and Nvidia, which are looking to push ARM-based processors into the data center.

Apple kills the optical drive, and other stories

Apple [AAPL] seems set to kill the optical drive when it releases Mac OS X 'Lion' as a downloadable upgrade via the Mac App Store. While this begs questions -- principally how a Mac user can launch a faulty Mac from disk, without a disk -- this isn't the first time Apple's changed an industry. Here's a short -- and necessarily incomplete -- list:

[ABOVE: The Alto in action, c/o Computer History Museum, copyright Mark Richards.]

Dude, where's the PC

"We started out to get a computer in the hands of everyday people, and we succeeded beyond our wildest dreams." Steve Jobs.

Way back when computing was text-based, an Apple team visited Xerox Parc, where it saw the Alto. Equipped with a mouse, keyboard and screen, Jobs seized on the new interface and took the ideas back to the Apple team. There, he told them, "Let’s make a dent in the universe. We'll make it so important that it will make a dent in the universe."

It did: Apple's GUI revolutionized the industry, gave Microsoft the ideas that became Windows, and while Apple is innovating the interface today, introducing touch, it is undeniable that Apple helped invent the computer world. Even though Commodore boss, Jack Tramiel, called the Mac a toy, admonishing Jobs with the advice, "I guess you'll sell it in boutiques".

Looking at the success of Apple retail since the company launched its chain of "boutiques". Tramiel was ahead of the curve.

From an Acorn an ARM tree grows

Remember the Newton? Apple's mobile solution created its own cohort of fans across its five-year history, and while the project was killed off by Jobs on his return to the cash-strapped company, people who worked within the team went on to help kick-start the mobile solutions industry at Palm, while an early Apple investment in a processor partner for these devices paid long-term dividends, history now shows: after all, Apple was a major start-up investor in today's leading mobile processor company, ARM.

[This story is from Computerworld's Apple Holic blog. Follow on Twitter or subscribe via RSS to make sure you don't miss a beat.]

Originally part of UK firm, Acorn Computers (Acorn's BBC Micro computer was widely-used in UK schools). Acorn was taken over by Olivetti in 1985, with the first RISC-based ARM processor arriving in 1987. ARM was spun-off from Acorn and Apple after they began working on an ARM processor as part of the development of the Newton. Fast forward to the low power demands of 2005, and about 98% of the more than one billion mobile phones sold each year used at least one ARM processor. Apple's own A5 (and the preceding A4) processors are based on ARM reference designs.

Without Apple's investments in the Newton, then Apple would have needed to invest in another chip designer to create its mobile processors.

Objectify me

You have to love Mac OS X. After being on the market for what feels like a billion years, but isn't, there's still no significant virus threats, there's still no significant malware, and despite the constant paranoid carping from security vendors, sensible password management and remaining aware of dangers in opening unknown images or using public wireless points is enough to keep most users safe.

Contrast this with the constant high-level security alert which is using Windows, or the known but criminally-under-reported huge great big yawning chasms of security problems on the so-called open Android OS. (So open Google can delete Apps from your phone if it wants to do so).

It wasn't always so. Way back in time Macs ran a form of OS called, appropriately enough, Mac OS. This quirky operating system was good enough to be fun to use, and charismatic enough that it created its own vast congregation, but it had too many limitations. Apple's own attempt at creating a new OS, Copland had failed --- so the company went scampering to evicted Apple founder Steve Jobs, and his new firm, NeXT, in search of a replacement.

NeXT was acquired for $400 million in 1996. Jobs finally returned to Apple with the deal. "It's perfect," said IDG's Bob Metcalfe in 1996. "The new team at Apple has Amelio and Ellen Hancock (CTO). They are extremely competent, but they lack one thing: charisma. Steve adds that to the mix." Within a year both Amelio and Hancock were out and Jobs had taken over as interim CEO, becoming full CEO in 2000.

And this is significant why? Mac OS X was the starry-eyed offspring of Mac OS and NeXT. Combining user simplicity with graphical features that made it fun to use, this easy-yet-powerful OS had abilities no other OS could match.

Take video handling, for example. iMovie bought movie editing to everybody's computer, but the secret reason Microsoft couldn't match it (until it finally got to grips with creating a truly competitive OS in the form of Windows 7) was because its systems just crumbled and died when trying to handle video. (I'm not saying Windows systems couldn't handle it, just that they couldn't handle it while doing something else).

MacBook Pro dropped from balcony in G-Form Extreme Sleeve

Last month we saw Tom Cafaro show off his G-Form iPad 2 cover with the aid of a bowling ball. No damage was done to the iPad even after the 12-pound bowling ball was dropped from a height of three feet. Well, Cafaro is back in another video with the MacBook Pro G-Form Extreme Sleeve for Laptops.

In the video below, we see Cafaro drop a shiny, new MacBook Pro from a considerable height. He doesn’t specify the exact height, but it’s from a deck high above the ground, that’s for sure. G-Form’s slogan, “Soft and Floppy, Extreme Protection,” makes us cringe a little, but it’s right on. The case is made out of a special material called PORON XRD, which lives inside the sleeve’s outer shell. The material is unique because it hardens upon impact. The foam shell absorbs the force somewhat, but the PORON XRD is what really protects the laptop.

Both the iPad video and the MacBook Pro video show Cafaro starting the Pixar short film “For the Birds,” and then inserting the iPad or laptop into the sleeve. Instead of seeing a bowling ball drop onto the MacBook, Cafaro drops the MacBook off a balcony, unzips the sleeve, opens the laptop, and voila, the 13-inch MacBook continues to play the adorable Pixar short as if nothing had happened. We would like to see the same test done with the MacBook landing on its edge rather than flat, though.

The case is designed for 11-inch, 13-inch, and 15-inch laptops. It’s available for pre-order now at $69.95 for the 11-inch model, and $79.95 for the 13- and 15-inch models.

Desktops and Notebooks: Apple iMac Features Fast Intel, AMD Chips, FaceTime HD Cameras: iFixit

Apple took a break from defending itself during the swirling controversy around iPhone data-collection practices to introduce its new iMac all-in-ones May 3. Arriving months before the previous models reached their first birthdays, their most notable updates include Intel ThunderBolt I/O technology, FaceTime high-definition cameras and speedy AMD and Intel processors, making for machines that are 70 percent faster than their predecessors and offer three times the graphics performance, according to Apple. Repair site iFixit quickly got to work on a teardown and found the ThunderBolt port IC to be similar but not identical to the technology debuted in the MacBook Pro, the same LG displays that Apple used last year, a win for Atheros, on the communications front, and the surprising option of being able to replace the GPU without springing for a whole new logic board. Unlike the repair-averse MacBook Air, the new iMac earned a repair score of 7 out of 10—making it "very respectable," according to iFixit.

Apple releases MacBook Pro and iMac EFI and Software updates

Apple has released a few updates for the firmware and operating system software for the latest MacBook Pro and iMac models, which address problems with Boot Camp, graphics stability and external display support, and also some bugs with the new Thunderbolt I/O connection technology.

These updates are specific to the new MacBook Pro and iMac models released this year that have the Thunderbolt technology, so if you have an older MacBook model then you do not need to download these updates. If you are unsure whether or not you need the update, just check Software Update on your system (in the Apple menu) and if the updates become available then you can install them from there. Alternatively, you can install them as standalone updaters:

MacBook Pro EFI Update 2.1 (3.06MB)

This update fixes a problem in the 2011 MacBook Pro models when running Boot Camp, where Turbo Mode would not work properly. It also addresses some graphics stability issues with the initial firmware release. After updating, the system's Boot ROM version will be MBP81.0047.B0E, which can be checked using the System Profiler utility.

MacBook Pro Software Update 1.4 (132.69MB)

Accompanying the EFI update for the new MacBook Pro systems is a software update fix that addresses the same issues with graphics stability and performance, and bug fixes to the Thunderbolt connections. After updating, the build version for OS X 10.6.7 on these systems will be 10J4035, which can be checked by going to the "About This Mac" option in the Apple menu and clicking on the "Version 10.6.7" text in the center of the window.

iMac EFI Update 1.6 (6.1MB)

This update addresses similar Thunderbolt issues on the iMac that are addressed on the MacBook Pro systems, though it appears this update does not implement any changes to the graphics system. After updating, the Boot ROM on your iMac will be IM121.0047.B0A. Keep in mind that this update requires that you initially install the software fix for these iMac systems, so if you apply these patches manually be sure to install that first.

Mac OS X 10.6.7 Update for early 2011 iMac 1.0 (382.56MB)

This software update for the new iMac systems is more than just a patch for a few drivers, and includes fixes for MobileMe services, Networking protocol handling, and some system applications in addition to the graphics fixes. The full list of changes in this update are:

Improve the reliability of Back to My Mac
Resolve an issue when transferring files to certain SMB servers
Address various minor Mac App Store bugs
Address minor FaceTime performance issues
Address issues with graphics stability and 3D performance
Improve external display compatibility
Improve Thunderbolt device support

Again, be sure to install this update before you apply the EFI firmware update for these iMac systems.

As always, be sure to back up your systems before applying these updates, and for the EFI updates be sure to follow the on-screen instructions. The EFI updates will download to your system and require a restart, where you will see a grey progress bar display while the update is being applied. The system may reboot a couple of times during this process, so be sure to allow it to fully complete and load the operating system. While it is being updated, be sure to have the system plugged into a working power source at all times (do not rely on the battery power during this update). The software updates (non-EFI) will just require a single restart and will not show a progress bar when being applied.

Apple releases iOS 4.3.3 to ‘fix’ location services issue

Wednesday evening I was busy updating my iDevices with the new 4.3.3 update. The update was released about Noon on Wednesday. This version update is Apple’s answer to the tracking of the device’s location and the fact the user of the device could not turn the “feature” off.

I spent about an hour updating two iPhones and two iPads to the newest updated version of the iOS software. At the moment, the update does not look like it’s broken anything. So we’ll call it a good.

I continue to be amazed at how easy these upgrades are and how reliable they have been. Each of the devices I upgraded this evening took between 10 and 15 minutes to complete and did not require that I do anything other than plug it in and click “OK” to upgrade. Couldn’t be easier.

For the techs in the room, the downloads where the following sizes:
- iPhone 4 – 667 Mb
- iPad 2 – 606 Mb
- iPad 1 – 560 Mb

So plug your iDevice into your computer with iTunes and get the update. And, won’t it be nice when we won’t need to plug in to update our iDevices…maybe in iOS 5?

Apple fixes location tracking glitch with iOS 4.3.3 update Read more: Apple fixes location tracking glitch with iOS 4.3.3 update - FierceMobileContent http://www.fiercemobilecontent.com/story/apple-fixes-location-tracking-glitch-ios-433-update/2011-05-05#ixzz1LUNFHzlb Subscribe: http://www.fiercemobilecontent.com/signup?sourceform=Viral-Tynt-FierceMobileContent-FierceMobileContent

Apple (NASDAQ:AAPL) issued its iOS 4.3.3 software update, which contains promised changes to the operating system's crowd-sourced location database cache. IOS 4.3.3--available via iTunes, and compatible with the iPhone 3GS and iPhone 4, the third- and fourth-generation iPod touch and the iPad and iPad 2--reduces the size of the location database cache from up to a year to about a week, halts cache backup to iTunes and deletes the cache entirely when users disable their device's Location Services feature.

IOS 4.3.3 follows on the heels of reports that devices running the iOS operating system store user location data in a hidden file--the new update fixes the software bug that Apple blames for cases where iPhones have cached as much as a year of location information. IOS 4.3.3 also arrives days before Apple and archrival Google (NASDAQ:GOOG) will testify at a Senate hearing on the subject of mobile phone privacy and location data collection: Sen. Patrick Leahy (D-VT) said last week that both Apple and Google will testify May 10 before the Senate Judiciary Committee's privacy subcommittee, headed by Sen. Al Franken (D-MN). Leahy said it is essential to have "complete and accurate information about the privacy implications of these new technologies."

The furor over location tracking exploded last month after British researchers Alisdair Allan and Pete Warden reported that iPhone and iPod devices had recorded location and time-stamp data since the mid-2010 release of the iOS 4 software update, effectively creating a comprehensive log of all user movement and activities during that time. Apple broke its silence on the matter several days later, explaining that iOS devices are in fact gathering location information to maintain a database of Wi-Fi hotspots and cell towers in the user's vicinity, enabling an iPhone to more rapidly and accurately calculate its location when requested. Apple added that calculating a phone's whereabouts via only GPS satellite data can take up to several minutes, while its approach can slash the process to a few seconds.

"Apple is not tracking the location of your iPhone. Apple has never done so and has no plans to ever do so," the company said in a statement. "Apple is now collecting anonymous traffic data to build a crowd-sourced traffic database with the goal of providing iPhone users an improved traffic service in the next couple of years. Our iAds advertising system can use location as a factor in targeting ads. Location is not shared with any third party or ad unless the user explicitly approves giving the current location to the current ad (for example, to request the ad locate the Target store nearest them)."

The iPhone location data fracas is the subject of a class action suit accusing Apple of invasion of privacy and computer fraud. The suit, filed Apr. 22 on behalf of iOS users Vikram Ajjampur and William Devito in federal court in Tampa, Fla., contends that Apple is secretly recording the movements of iPhone and iPad users and seeks a judge's order barring the practice. "We take issue specifically with the notion that Apple is now basically tracking people everywhere they go," Aaron Mayer, an attorney for the plaintiffs, told Bloomberg. "If you are a federal marshal, you have to have a warrant to do this kind of thing, and Apple is doing it without one."

Ajjampur and Devito are also requesting refunds for their iOS product purchases, contending they would have steered clear of Apple devices had they known about the potential for location data tracking. The lawsuit seeks unspecified punitive damages for alleged negligent misrepresentation. Anywhere from one-third to one-half of the U.S.'s 60 million iPhone users could be part of the class, Mayer added.

Next Generation Cloud Messaging API Focused on Android and Windows Phone 7

COOPER CITY, Fla.--(BUSINESS WIRE)--Linxter, Inc., provider of message-oriented cloud middleware, today announced the version 2.0 release of its Software Development Kit (SDK). The Linxter cloud messaging platform simplifies mobile and distributed app development by enabling software engineers to implement secure, reliable, durable transactional data exchange on Android, Windows Phone 7 and anything .NET or Java. The Linxter SDK, sample code, and video tutorials are available at http://linxter.com.

“Linxter 2.0 brings new features and performance improvements to the cloud messaging market”

“Linxter 2.0 brings new features and performance improvements to the cloud messaging market,” stated Jason Milgram, Linxter Founder and CEO. “We have added audit copy capabilities, introduced privileged program instances, and increased performance of our Internet Service Bus (ISB).”

Message-oriented cloud middleware -- also known as cloud messaging -- is like email for programs. Using Linxter, programs can securely and reliably exchange data and file attachments. Built-in controls allow businesses to manage who or what can send and receive messages, and enforce changes in data exchange rules as needed.

Linxter v2.0’s audit copy feature allows companies to adhere to government compliance requirements like SEC Rule 17a, Sarbanes-Oxley, and HIPAA. With this feature, a company can specify whether to have an audit copy made of messages sent and received by instances of their program. Companies can designate to send audit copies to an on-site location or to a third party data retention provider.

Linxter v2.0’s privileged instances feature receives incoming messages sent to all instances of a program, and distributes or processes them according to an app’s requirements. Individual (non-privileged) instances operate normally, maintaining their ability to manage communication channels and send messages. This concept is similar to an SMTP server, which receives all email messages and distributes them to the individual email accounts on a server.

Linxter 2.0 reflects our continued commitment to innovation. With our first public beta release in May 2008, Linxter became the first cloud messaging platform providing secure, reliable, durable transactional data exchange between applications. Our message reliability and durability continue to set us apart from other cloud platforms.

Reliability and durability is achieved in part due to the use of flat transactions in every message exchange. A message being sent is not removed from the sender’s local queue until its successful delivery is verified. With the new features added in version 2.0, in addition to the host of features currently provided, Linxter strives to remain the cloud messaging platform of choice when security and reliability matter.

Bank of America cashes in on Windows Phone 7 with new app

Bank of America has finally made its appearance on Windows Phone 7.

Via the company’s new app, Bank of America customers can check their balances, transfer cash, pay bills, and find the nearest Bank of America locations. (According to MobileTechWorld, that latter functionality works pretty well with WP7’s integrated Bing Maps feature.) Obviously, security is a major concern with mobile banking, but Bank of America says that the app’s transactions get the same level of security as their online counterparts.

Bank of America already offers the same app on the Android Market Market and iTunes Store, but Microsoft is apparently so proud of the WP7 version that the company featured the app on its Windows Phone Blog. You take what you can get, I suppose.

Use an Unofficial Windows Phone 7 Update? No Security Patch For You

Did you use a homebrew solution to force the Windows Phone 7 "NoDo" cut and paste update? You might be out of luck when it comes to security upgrades.

Microsoft announced Wednesday that people who used an "unofficial update mechanism" to upgrade to "NoDo" will not get a security upgrade that started rolling out yesterday. In a blog post explaining the situation, Microsoft basically said we told you so.

"We cautioned that phones which were updated via this method were not going to be able to update past build 7390," Microsoft's Brandon Watson wrote. "Unfortunately for those customers out there who acted on information from sources outside of Microsoft, the rubber meets the road today."

Updates for the Windows Phone 7 platform have had a bit of a rough road, prompting delays. For those who didn't want to wait, the developer behind the short-lived ChevronWP7 jailbreak for Windows Phone 7 posted a new hack that let users bypass Microsoft and carriers to update their mobile operating system.

In early April, Microsoft cautioned against using this method. "Bottom line: unsupported workarounds put you in uncharted territory that may void your phone warranty," Microsoft said at the time.

As a result, the recent "7392" security update, which fixes nine fradulent third-party digital certificates, will not be available for phones that used the Chevron workaround.

"With the official update process there is a requirement that the package on the phone also be official in order to update itself," Watson wrote. "Phones updated via the unsupported method do not contain an official image and cannot be updated further at this time. Due to scheduling of engineering resources, we did not anticipate having to undue the changes made to phones by these unsupported methods."

Microsoft is not completely ruling out a future update, but "for now there is no fix." The Windows Phone 7 team is now focused on the current security update and the next major platform update, codenamed Mango. "Undoing this specific problem was not in our schedule," Watson said.

That being said, the team that developed the workaround might have a solution.

They "wanted to get a timely fix created for customers who have put their phones into this state," Watson continued. "They believe they have created a way to get these phones back on the officially supported path. We will work with them to validate their solution and applaud the team for taking responsibility to do this."

Windows 7 Tweaks for everyday use

In case you think your Windows 7 is slow-moving, then you should understand you're not the only one who is going through this difficulty. A lot of people are already enduring identical concerns yet the great news is that this kind of difficulty may be resolved through the help of some windows 7 tweaks. In this posting, we're going to focus on a few good adjustments that will help you make your Windows 7 speedier.

To start with, you must ensure you have proper equipment pieces. Although sluggish performance of machines that operate Microsoft Windows 7 typically have nothing much to do with the actual computer hardware yet it is preferable to ensure suitable computer hardware designs. Listed below are the typical configurations of computers that may have MS Windows 7:

1. Processor speed of 1 Giga Hertz or higher

2. Memory space or Ram of 512 Megabytes or more

3. Disk drive with 20 GB or even more storage space

Right after making certain minimal computer hardware need is satisfied, you may improve functionality of Microsoft Windows 7 by testing these windows 7 performance tweaks described here:

Get rid of the software applications that you're never using:

While exploring Internet, people encounter programs they believe are extremely helpful. The majority of individuals set up these applications hastily yet don't utilize them. You may have installed such software on your hard drive and may additionally have received many software which were already set up op on your computer or laptop when you initially got it but are not making use of these. Identify these types of software applications and remove all of them. Keep in mind, software applications use system resources even in case you are not making use of it. Therefore, it's preferable to do away with these kinds of programs.

Alter the Startup Configurations:

Your personal computer requires a large amount of hardware resources when it is starting out. Software setup tools manage those items that run at startup of computer systems. Often, startup things extend the operating system boot time frame since they need memory and CPU time. For this reason, you should assure that your system do not have a great deal of startup things. You could remove the startup applications by stopping the startup programs by means of built-in Startup settings application. Yet be cautious in setting up the applications because switching off some vital computer programs might end in fatal problems.

Defragment hard drive:

Whenever you put in and uninstall different computer programs, it may lead to wastage of space on hard drive. By defragmenting your hard disk, you may be sure that system records are put together one after the other on hard drive as well as the space is used optimally. There's a built-in tool in Microsoft Windows 7 that may enable you to carry out defragmentation of hard disk drive. This could increase the overall performance of your PC.

Clear Computer registry:
