Quite frankly I think that the problem is more serious than just the MS updates.I managed to damage the machine to such an extent that even after ordering recovery disks I was not able to restore it -- the hard disk drive password was frozen.Acer managed to get it running again but the secure boot is now not configured correctly and I have noticed numerous issues, such as freezing, apps not working, etc.Running sfc /scannow I get that there are problems that the tool was not a able to fixDISM.exe /Online /Cleanup-Image /CheckHealth gives a clean reportBut DISM.exe /Online /Cleanup-image /Restorehealth reports that there were errors, but that they have been repaired.(That is as much as I know to do.)I have used Kaspersky, McAfee, Avast, Malwarebytes, rootkit tools. Nothing has been flagged.Clint.
