Hi Marty, I wouldn't recommend rolling back.Could cause even more problems. See if they can try fix the problems they have, that would be best. I have had good and bad feedback from Microsoft Support. Perhaps your friend might want to give them a call to see if they can help. It's very hard to offer any other advice without seeing the computer. Have they got a good backup system in place? I would recommend finding a good technician to help if they are serious about rolling back. Keep in mind Microsoft don't support Windows 7 anymore. Microsoft only provides security updates. I would recommend anyone with Windows 7 that is eligible for the free Windows 10 upgrade, take it up soon as it ends in July.

Are you sure it was automatic or client error ? If automatic how do others safeguard from this from happening? Many things break and issues occur when upgrading operating systems, particularly if your business is dependent on older more specialised Windows software.
