Sounds like you wrote over Windows, including the registry, and all that is left is the program data on the drive.
If they aren't showing in add/remove they haven't been registered (most likely).
You should be able to safely delete what you don't want.

On another computer, if you check the Control Panel - add/remove programs area you'll find most of the installed programs show up there.


I do not work here, but the benefits are still awesome
