When you install an application in Windows XP the software also adds an uninstall option. This is usually stored in the Add/Remove programs section of the Control Panel. When you want to remove the application you simply go to Add/Remove programs, click on the application you want to remove and away it goes. Sometimes, however, although the application disappears, the entry still remains in the Add/Remove list. Here is how you remove it.
Before making any changes to the registry it is recommended that you make a backup copy of your registry either from within the registry Editor (see 62. How do I backup the Registry in Windows XP ) or by using the freeware registry backup utility called ERUNT (available from www.larshederer.homepage.t-online.de/erunt This is the main German site. Alternatively you can obtain ERUNT from http://www.majorgeeks.com/Erunt_d1267.html ).
