Okay. I've tried upgraded my laptop to Windows 10 but things didn't go ad planned. It got stuck at 91% for about 5 hours. So I did what anyone would do and contacted Microsoft. They send me a technician and he told me to force turn off my laptop. So I did. After that it restored back to Windows 8. He told me that he will remotely control my laptop and try to redownload. Guess what! Got stuck at 91% AGAIN. any idea what to do?
