Windows 10 was running well on my Mac with Parallels Desktop 12 until recently. But now when I start W10 it ends with some kind of test and gets stuck (see screen dump). A backup of some days ago works find, but after one or two restarts the same problem occurs. It seems so be connected with a windows update that Parallels doesn't appreciate. Does anyone have the same problem and/or a solution? Joep
Yes, I don't keep track of it but almost every day I have this message 'Windows may be slower due to updates' or something like that.
