Is it possible to repair Windows 7 without the disk?
This PC hasn't been scanned for a while. Last time the PC was on, it was scanned using Avast Free Antivirus. It detected some corrupt zip files, worms, etc in the Windows folder. I chose to delete them all. At 50% through the process, I decided to manually restart it by pressing the power button. As it came back on, Windows Repair ran.
Is the repair provided different from the repair the CD provides?
Last known good config
and try it.
