Since you are using WinXP, it is a really good idea to use the System Restore facility. This is one of the really nice features in XP, as it allows you to restore the PC to a prior state.
Not all applications have a clean Uninstall script and leave registry entries and sometimes DLLs behind. System Restore will ensure that the system is restored to exactly the state it was at the time the Restore Point was taken. Note, however that the number of restore points that you can save depends on the amount of disk space that you have allocated to it. The space is configurable up to about 12% of total space (see Help for System Restore) on a per disk basis.
System Restore does not change user documents, so if there are configuration changes or what it considers are user documents in the installation directory, it will rename the directory and let you know so that you can deal with those manually.
System Restore is particularly useful when you have an unbootable system, caused by a driver issue (provided that you saved a Restore Point before installing the offending driver). You can usually boot up in Safe Mode (without most drivers), and restore to one of the previously saved states. Particularly useful if the Last Known Good facility fails due to a situation like... the system booted ok and just after loggon, it locked up
When you use Windows Update it automagically invokes the saving of a Restore Point, but lots of application program installers don't do this yet, so you have to do it manually before installing the application. :bigsmile:
To use it go to Start-->Help and Support, then click "System Restore".
Not a substitute for Uninstall, but can rescue the system when a new installation decimates stability or functionality or if you just want to test an application and then wipe all vestiges of it from the system.
