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
By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.
Use Disk Cleanup to:
• Remove temporary Internet files.
• Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).
• Empty the Recycle Bin.
• Remove Windows temporary files.
• Remove optional Windows components that you don't use.
• Remove installed programs that you no longer use.
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.
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:
• You add a large number of files.
• Your free disk space totals 15 percent or less.
• You install new programs or a new version of Windows.
To use Disk Defragmenter:
1.Click Start, point to All Programs, point to Accessories, point to System Tools, and then click 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:
1.Close all open files.
2.Click Start, and then click My Computer.
3.In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
4.In the Properties dialog box, click the Tools tab.
5.Click the Check Now button.
6.In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
7.If bad sectors are found, choose to fix them.
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.
Learn all about ReadyBoost
If you're using Windows Vista, you can use ReadyBoost to speed up your system. A new concept in adding memory to a system, it allows you to use non-volatile flash memory—like a USB flash drive or a memory card—to improve performance without having to add additional memory.

When you use My Network Places to browse for other machines on your network, it usually takes a long time to display the list of shared resources for the target machine. This is because Windows XP first checks for the scheduled tasks on the target machine before listing the shared resources present on the computer.
To schedule a task using Windows XP’s Scheduled Tasks, choose Start –>Programs –> Accessories–> System Tools–> Scheduled Tasks.
This unnecessary checking can easily add 30 seconds of delay. You can decrease the time browsing takes by modifying the Registry to turn off this checking:
Invoke the Registry Editor by typing regedit at the command line or in run window.
Open the Registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\
Remote Computer\NameSpaceDelete the following key (the value for it is the Scheduled Tasks)
{D6277990-4C6A-11CF-8D87-00AA0060F5BF}Close the Registry and reboot

If you have 512 MB or more of RAM, you can increase system performance by having the Windows XP 'Core' kept in the RAM instead of paged on the hard disk.
Go to Start -> Run - Type regedit and press enter - On the left hand side tree, navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\
- On the list on the right side, look for an entry called 'DisablePagingExecutive'
- Double click it
- Press 1 on your keyboard
- Click OK
- Exit regedit and reboot the computer
To revert to the default setting, follow the same steps as above, but this time, press 0(zero) instead of 1 on the keyboard.

Nobody wishes to install anything in their C drive or the windows drive as it results in slower performance of the computer.
The default installation directory on windows is C:\Program Files into which new programs are installed. What if you wish to install all the programs into another directory on another drive?
However, you can change the default installation drive and / or directory by using a registry hack.
Start
Run
Type regedit
Go to this directory:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
Look for the value named ProgramFilesDir. by default,this value will be C:\Program Files.
Edit the value to any valid drive or folder and Windows will use that new location as the default installation directory for new programs.

These days Agents spy on u everywhere, in college, at work, maybe a trojan virus on your home PC which keylogs your paswords and mails it to someone else. If u think u r being logged, try this:
Whenever u have to type a password, never type the complete password in one go, ie, if your password is WINDOWS, u should type NDOW, then move cursor to start of the password field using the mouse ONLY, then type WI, then move cursor to end using the mouse and type S. This way the logger will record your keystrokes as [ndowwis] instead of [WINDOWS].
keylogger fooled.
