It seems that almost every Microsoft Windows 10 update breaks something on my PCs. The last one resulted in two issues: PC1: pin is no longer recognized by Microsoft, so I cannot log into my PC. The link provided in the message does not work. Thank you Microsoft. PC2: I have a message that I need to register my Windows 10 software. That has been done at least twice in the past. Thank you Microsoft. Why, oh Why didn't I buy a Mac instead of a Windows based PC? I knew better, but I didn't want to spend the extra money. I did not take into consideration the many hours I have spent resolving the problems caused by MS untested updates. Shame on me!
