How to Restore a Removed Program on Windows XP
System Restore is a Windows XP feature that allows you to go back in time to fix or undo system settings. If you have a program that you removed, uninstalled or became corrupted after an update, you can go back and restore your program or set it back to its original settings.This easy to use feature creates snapshots known as restore points which allow you to go back up to 30 days to restore programs that have been removed.
Click "Start" then highlight "All Programs." Highlight "Accessories" then click "System Tools."
Click "System Restore." A system restore wizard will open up.
Click "Restore computer to an earlier time," then click "Next." Select a day and restore point before you removed/uninstalled your program to set your computer back to.
Click "Next." The System Restore will shut down Windows and begin the restoration process. When the restoration is complete, Windows XP will automatically restart. Your computer will be restored to the settings and programs of your chosen previous state.
Check the location that you had originally saved your program before you had removed it to begin using your restored program.
