W10 Reformats hard drive and reinstalls at least twice a day
I upgraded to W10 from W7 several months ago. In the succeeding week, W10 reconfigured my hard drive at least twice a day and, in the process, deleted all my files. Fortunately, I had a backup, but I replaced W10 with W8 and have had no problems since. I don't care to try W10 again.
