Remove programs entries with regedit

Generally we use Add/Remove programs option in Control Panel to remove any unwanted program from our computer. Normally this may be due to poorly designed uninstaller with this program. That is why some programs may not be removed properly and a reference to this program remains in the computer registry. This reference in registry may be creating problems to run your computer smoothly. Here you need to delete this reference to edit your computer registry using RegEdit editor.
First go to Start button and open Run dialog box. Type here RegEdit and press Enter.
Now in editor Navigate to the given path
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstal
Here locate the entry created by your program with its name and select that entry from the list on the left panel and delete its key.
Close the Registry Editor and restart your computer, the program will be removed from your computer permanently.
