This is one of the common problem which I used to face in college times. Some of the software used to still have the entry in Add / Remove section of windows XP even if I have used the un-installer to remove the application or program. Here is a quick solution to remove them from Add / Remove Section
- Type regedit in your run dialog box [Win Key + R]
- Now look for the this string HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionuninstall.
- If the software name is still here which you removed already, delete it from here.
- This will delete it’s entry from the windows ADD/ Remove Section
This should work on Windows Vista as well though I have not tested it yet. I will update here If I do.
