Entire Windows folder has vanished

[ellenc]

You may have trouble believing this, but the ENTIRE WINDOWS FOLDER on the hard drive has vanished. I've been using my machine as usual although am having some bad problems, such as not being able to download/install since Windows Installer is also gone. I guess that's part of the Windows.system 32 stuff that disappeared.
I have a bad feeling I'll have to reinstall Win 7. How in the world could something like this happen? I have the old Windows folder from XP on the drive but no Win 7. Fortunately, I obssess over backing up and have Carbonite, Acronis True Image, Windows BU and everything on Seagate external drives. Many thanks for your ideas. ec
