Windows 10: Explorer.exe crashes when pressing Alt+Tab

Hello,


I'm currently facing an issue where explorer.exe is continuously crashing when I alt+tab.

I've also noticed it when trying to do other things such as snap an explorer window to fill half of my screen.

This issue started occurring just this week and I checked my latest Windows updates and noticed I installed were the following.

I also tried running the system file checker and DISM to repair any corrupt files.

This did not seem to work.


Any information helps.


Thank you.

alt + tab not working

Alt-Tabbing in & out of games does not always work. It can also crash games in some cases.

 

Alt + Tab = Crash

Good evening,

It appears that Windows 10 keeps crashing whenever I Alt + Tab out of a game and then attempt to go back in. When I Alt + Tab back in I'm met with a black screen. Then Windows 10 freeze and I can't do anything.

Steps to reproduce:

(1) Start game

(2) Alt + Tab out

(3) Do whatever in Windows 10

(4) Alt + Tab back in

>>>Black screen

(5a) Ctrl + Alt + Delete to end process of game

(6a) No clickable buttons in Windows 10 (can't even shut down)

(5b) Ctrl + Alt + Delete

(6b) Shut down (just spins indefinitely and doesn't actually shut down)

This is a on a brand new copy of Windows 10 (not an upgrade). My current specifications are below:

-5930K

-MSI SLI Plus X99 Motherboard

-16 GBs 2800 MHz RAM

-2x NVIDIA Titan X GPUs

-512 GB M2 SSD

-1600w EVGA PSU

Please advise on what is happening and if this will be fixed soon.

 

alt tabbing increases system performance?

Alt+tab often forces the game to reinitialize the DirectX renderer. It's likely an opportunity to reattempt to start SLI/Crossfire if it didn't start with the game.

Mind you, alt+tab is as likely to cause the game to crash as it is to improve performance. Some games support it, some don't, and some are somewhere in between.
