If there would have been violations that couldn't be fixed, then we have a problem. Did you upgrade them all at the same time and have you tried the windows reset that I posted in post #49 yet! I don't know this for sure, but if no violations were found when you ran a sfc /scannow that would be a good sign that your windows files are good. Maybe the up dates will install latter as suggested. 2 out of a 100 seems a little high to me! You upgraded 3 PC's and only have a problem with one of them. There will always be haters and doubters of W10.
