Clear Add Remove Programs list

Certain program entries do remain in the Add/Remove programs
list due to some incomplete install/uninstall.
This small registry tweak allows you to remove all the unwanted
entries from Add/Remove programs list, it can also be used to hide
the Installed program from appearing in Add/Remove list.

To do this, go to registry and follow the following path:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

Under this key you will find the sub keys for each program installed.
Right Click and delete all the entries you want removed from Add\Remove
programs list.
