My dad had the same issue, and now my computer wants to do this update as well. I'm really scared it's gonna completely bust my computer and I seriously cannot afford another one, and I need it for school.
I'm hoping Microsoft fixes this update soon (or even better, gives us optional updates). If this breaks my computer completely, then when I manage to get enough money I'll probably move to another operating system. I'm just done with the glitches I get with this computer already. I've put up with it because it hasn't been too bothersome, but if my computer breaks? I won't stand it anymore.
Please fix this, Windows. I want to be a customer for you guys because I love these computers, but this has just gotten terrible. Meanwhile, I'll try to avoid this update at all costs.
