Remember that Windows is a virus with mouse support.
OS Rot really happens, and sooner or later, a complete re-install is inevitable. One of my favorite tricks is to partition my drive with a 1 - 2 GB C: drive. You can partition the rest of the drive, or leave it as one large D: drive, and put everything (and I mean
EVERYTHING!!! other than Windows, itself, on the later drives.
Then, when the time comes, as it surely will, just format C:, and re-install Windows. You will have to re-install all your other programs, but all your setups and data files will be in place and ready to roll.
