Just an FYI, I tried the new Windows 10 Fall Update that launched a couple days ago. I had to revert back to the Windows 10 Creators update after a couple days as the Fall update for me was unstable. After installing it IF I were playing a game and switch between windows (it also happend a couple other times between different programs) would cause my whole new computer to lock up completely. I would have to reboot in order to use my computer again. Reverted back and back to having NO issues. I even tried checking event logs but no errors were logged etc.. for it.. I tried to also reinstall a few programs that I had running to see if it was a program causing it. So I would hold off for a while OR maybe it just needs to be a clean install. I just installed windows 10 with the creators update a couple months ago (new computer) so I just updated to the Fall update the other day.
