for some odd reason after playing some games the last game i play gets frozen after 3 seconds AFTER the champion select at the loading screen and then it does not let me alt-tab or even close it down or even worse disables the windows key ????? i dont know what is happening and i dont have pics bcs i cant screenshot since i cant get out of that thing
Yeah, happened to me too once with the new launcher.
There are ways to interact with the Task Manager even though the loading screen is stuck on the screen.
Start off using ctrl+alt+del to bring up task manager.
Once it's up you can Alt+Tab to it even though it wont show on screen and use the arrow keys to move to the process that is not responding and then hit the Delete or End key to terminate the process.
I have to do the above often.
If you can't Alt+Tab or open Task Manager, then there is a workaround for that (for the next time it happens anyway):
