Windows - Add Remove Programs - Manual Removal (PCS002)

 

The Currently installed programs list in the Add or Remove Programs tool lists all of the Windows-compatible programs that have an uninstall program or feature. Occasionally, a program may not be removed completely, and the registry key that is used to display the program in the Currently installed programs list remains. In this situation, you may need to manually remove the program from the Currently installed programs list in Add or Remove Programs. To do this, follow these steps.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
