I did a restore on Windows 8, got a Windows.old folder. While I was trying to figure out what to do with the folder it is now gone. I need documents, pictures, etc. in that folder! How can I get it back!
You could try any of the file recovery applications....Recuva, perhaps.
But for the whole of the windows.old to find a few specific files? I'd not hold out any hope. None at all.
