Question about adding programs to registry

I recently reformatted my main hd and got a new OS on it. I haev a second sata drive with all my games/programs, and I was wondering how to add these programs to the registry w/o reinstalling.

Help pls.

You reinstall them.

The only way to do what you're asking is to image a clean copy of your drive before formatting it.

you could add them by hand if knew what keys to make where but that would be stupid. Alot of apps will work fine without reinstalling

Ok thanks for the help guys.
