WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
Programs that are compatible with Windows may have an uninstallation program or feature. The Add/Remove programs tool lists all of the Windows-compatible programs that have an uninstall program or feature. You may need to manually remove the program from the Add/Remove Programs list if you uninstall a program and the registry key that is used to display the program name is not removed correctly:
Click Start, click Run, type regedit in the Open box, and then press ENTER.
1. Locate and click the following registry key:
2. After you click the Uninstall registry key, click Export Registry File on the Registry menu.
3. In the Export Registry File dialog box, click Desktop in the Save in box, type uninstall in the File name box, and then click Save.
Each key under Uninstall represents a program that appears in Add/Remove Programs. To determine which program that each key represents, click the key, and then view the following values:
DisplayName - the value data for the DisplayName key is the name that is listed in Add/Remove Programs
UninstallString - the value data for the UninstallString key is the program that is used to uninstall the program
4. After you identify the registry key that represents the program that is still in Add/Remove Programs, delete the KEY.
5. After you delete the key, open the Add/Remove Programs window from the Control Panel.
6. In Add/Remove Programs, verify that the program for which you deleted the registry key is not listed.
If the program list is not correct in Add/Remove Programs, you can double-click the Uninstall.reg file on your desktop to restore the original list of programs in the registry.
