I'm not sure...but if the programs you have, are registered to the computer, I would have thought the upgrade shouldn't affect them.

None of my programs/apps were affected, apart from new ones added lol.

But it may be worth your while reading up on the microsoft forums.

Bela is correct. The only things that were affected were some minor games however the website that hosts them is working on it. If you wish to be extra safe just back up your custom items on an external drive.
