I installed Windows 7 and activated it. Now I have gone into Control Panel > Uninstall A Program. All of a sudden there are only 7 programs in there. I can't uninstall anything else. They are still on my computer and working, but why have they all disappeared off this list? Does anyone have a solution for this to get my programs back in there? Thanks.

Have you used any registry cleaner that you should'nt be using?Doc

I hadn't used any registry cleaners. I used CCleaner after I encountered the problem as I thought it might help, but still nothing. What other kinds of program may have caused this to happen? They were all there to start with and now they have suddenly gone. I have installed AVG Internet Security. Do you think that might have caused it? Not sure where else to look. Thanks.
