Last Friday, I received my alert about my Notebook PC (previously running Windows 8.1, that I just purchased in November and had yet to actually use much because it was bought to be a school-PC for me to use for college) was ready to upgrade for free to Windows 10. I followed the command prompts and by the time I had to go out on Friday afternoon - my installation was 12% complete (my dad too did the installation on his PC and it went smoothly and was already fully upgraded at this point). I came home a few hours later and my PC was rebooting on a loop. It would show the ASUS screen, flicker through another screen, turn a lighter shade of black, state that it was restoring my previous version of windows, shut down completely and then the whole process would repeat again. I left it alone Friday and Saturday and finally called Windows today when it was still repeating on a loop. Windows support tried to help but I was unable to access safe mode. I didn't feel secure with trying to fix the OS myself so my dad took it into Staples. Staples told my father that the Windows 10 "upgrade" completely destroyed my computer. It no longer has an OS at all. It's just an empty box.
Staples reminded us that we had purchased extended warranty and said that the warranty people would send us a coupon to come back and get a free replacement from the store if we called them. My dad spoke with the warranty people and was told that they do NOT cover issues like this at all. So not only is my Notebook PC completely destroyed and an "empty box" as Staples said, but I also can't have it replaced because the extended warranty that we paid for apparently doesn't cover it.
UNSATISFIED!!!! Thanks a lot Windows 10.
