Windows 10 - Alt-Tab crashes Zwift and PC

ALT-TAB used to work in W7 to enable me to exit Zwift full screen mode to go back to Windows. After upgrading to W10 Zwift now seems to do 3 attempts at exiting, then W10 crashes and restarts. The Windows error seems to be video related

Also, Zwift will not start unless in administrator mode.

Mate can I suggest if you haven’t already update your graphics card drivers, I am running on W10 Pro and not having any issues alt tabbing.

Also you might want to check that your UAC is set to the correct level and that your account is actually an administrator.
