Let Windows XP Take Out the Garbage
Aside from manually removing programs from the operating system there may be other unused files that need deleted, you can ask Windows XP to do this for you. This marvelous feat is accomplished by running a beautiful little program on XP called Disk Cleanup.
Click on the Start menu button. Point to All Programs> Accessories> System Tools> Disk Cleanup. The program will start right away, but it may take a few minutes to scan your hard drive.
If you have multiple hard drives, then you’ll need to run the program on each one.
After scanning your files, Disk Cleanup will display a list of files. These files are usually stuff that your computer gets from the Internet, such as temporary files and downloads. Check the boxes next to the files that you want to delete, and then click on “OK".
At this point, it is highly recommended that you make yourself some coffee, because Disk Cleanup will take a while to do its job. When you come back, enjoy your faster computer.
