URGENT: Cannot run exe in windows folder after uninstall app (using C# Setup Project).

I will be posting in the Windows XP group as well.

I have created a windows install package using VS2005 for my C# application.
Install the app on my PC and tested OK.
Problem comes after I uninstall it.
There are some registry entry not cleaned up by the installer.
I delete some of the registry entry (sub-key) in the Local Machine and Current User.

Now and cannot run any exe that is in the "c:\windows" folder.
The Windows Explorer type column for these files is also empty.

How can I recover my PC?
