. . .I think. I was transferring files from my old pc to my new pc and tried to open up an exe file and the "open with" box asked me to choose a program to open it with. I selected Windows Media Center. The "always use the selected program to open this kind of file" was checked, and I couldn't uncheck it. After that, all my programs want to open as Windows Media Center.
I have tried system restore but it errors out on me.
I have tried "regedit" but it doesn't work.
I have scanned for virus with Panda on-line (since my MCAFEE won't open).
Any ideas of what I can do?
