I have been in computers for a long long time, previous generations of windows updates causing issues led us to turn off auto updates, as we had security measures in place that a remote hacker could not do whatever, and got tired of computers crashing or going off line as they were needed 24/7. So young kid working for me at the time, update windows always, certainly ate up hard drive space fast, but I was like, win 10, I'll update, he is like no no, sorry going to do it anyway, I need to determine what issues we will have with our current universally installed programs, antivirus, backup etc. Sure we had issues, sure I fixed them, but I hope car updates go better than windows updates. PS if you have the latest version of windows, windows restore is turned off by default, gotta turn that on, had the powelike hit a computer this am, removed the trojan, but missing windows restore, as I could have just used that.
Thugh it never really caused a problem due to my lockdowns including more technical details if you are interested. Basically a reboot restores previous configuration by not allowing permanant changes, but powelike is a particularly nasty bug. If you get a mozilla needs upgrade and the web address is not mozilla.org do not go there.
