5 ways to Speed Up Your PC

By following a few simple guidelines, you can maintain your computer and keep it running smoothly. This article discusses how to use the tools available in Windows XP Service Pack 2 (SP2) and Windows Vista to more efficiently maintain your computer and safeguard your privacy when you're online.

	Free up disk space
	Speed up access to data
	Detect and repair disk errors
	Protect your computer against spyware
	Learn all about Windows Vista ReadyBoost

Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.

To use Disk Cleanup

1.	Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
2.	In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.   Choose the files that you want to delete.
3.	Clear the check boxes for files that you don't want to delete, and then click OK.
4.	When prompted to confirm that you want to delete the specified files, click Yes.

After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.

Speed up access to data

Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.

Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.

When to run Disk Defragmenter
In addition to running Disk Defragmenter at regular intervals—monthly is optimal—there are other times you should run it too, such as when:

To use Disk Defragmenter:

1.	Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.   Click Analyze to start the Disk Defragmenter.
2.	In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button. After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives. Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.
3.	To defragment the selected drive or drives, click the Defragment button. Note: In Windows Vista, there is no graphical user interface to demonstrate the progress—but your hard drive is still being defragmented. After the defragmentation is complete, Disk Defragmenter displays the results.
4.	To display detailed information about the defragmented disk or partition, click View Report.
5.	To close the View Report dialog box, click Close.
6.	To close the Disk Defragmenter utility, click the Close button on the title bar of the window.

Detect and repair disk errors

In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.

If you use your computer daily, you should run this utility once a week to help prevent data loss.

To run the Error Checking utility:

Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.

Protect your computer against spyware

Spyware collects personal information without letting you know and without asking for permission. From the Web sites you visit to usernames and passwords, spyware can put you and your confidential information at risk. In addition to privacy concerns, spyware can hamper your computer's performance.
