Initially did the email install not the clean install. Had problems. Then did the clean install all worked great for a week. Then perhaps and update or install of a new software? Who knows. Back to hanging problems. So I thought I could revert back to Windows 8.1. Nope that option wiped out. So I thought ok clean install of windows 8.1 Nope requires product key wiped out by install of Windows 10. I have a Toshiba Laptop Sattellite and I checked over at Toshiba to see if my model supports Windows 10 which I should have done in the beginning. It does kinda support it with certain updates. Tried those. Nope still have hangs. Deleted suspected updates as a last ditch. I cannot delete three of the last Microsoft Updates of 8/27 time frame. About had it. Gallon of gas and a match coming up for this Trashiba peace of crap. No product keys? Read where you can get it in the BIOS etc blah blah but not for this model. Went back to try to do the update sent sent by windows from my gmail. That email is not in my email folder anymore. Ok. Any ideas? I am willing to try fixes but I need to do something ASAP this is my work computer.
