Back-up...... and delete
The entire fix for this mess:
Remove the HDD from the afflicted machine, connect it to another machine with one of the numerous recovery Linux distros installed. Recover all the (l)user's files. Back them up to a couple of different media. Delete Windows and install from a Linux Mint DVD. Copy all the (l)user's files to the Home directory of their new system. Spend 10 minutes showing them how to log in, locate their files and configure their Email. Job done. No further "service calls" from "Microsoft" and a computer that runs as it should.
Biting the hand that feeds IT
