Windows 10: Alt+TAB back into video game. Can't use any ability's. Please help.

So I've noticed that in different video games like league of legends for example. When I alt tab out of game then to back in sometimes I can't use any of my abilitys with the keyboard Q, W, E, R and the number keys but typing in game chat works fine. This seems to happen in other games too. I have noticed sometimes if I CTRL+ALT+DELETE and open task manager it fixes the problem but if I alt tab out and back into game it stops working again. Does anyone know what might be causing the issue and how I can fix the problem? Happens in fullscreen and borderless window mode.

Weird alt-tab out of fullscreen games.

Hi Simon,

The multitasking capability of a game depends on the total memory of your computer. If you have large amounts of RAM on your computer, it can multitask heavy programs easily like high-end games. To ensure that we can provide the appropriate resolution
for your concerns with the alt-tab function, we’d like to ask you a few questions:

• What were the recent changes made on your computer before you experienced this issue?
• When did the issue start?

• Have you pressed the alt-tab key during you play Rainbow Six Siege? Or it just happen without pressing it?
  
• Does the automatic ALT-TAB behavior happens on other games?
• Do you have any other programs running on your computer while playing?
• What is the anti-virus program you're using?

• What is your device or system specifications? To know, follow these steps:
  1. Press Windows + S and type
     About your PC.
  2. Send us the information listed under Device specifications.
  
  

Moving forward, if you're multitasking while playing, we recommend that you play this game only without doing other tasks. Pressing ALT-TAB or performing a multitasking interferes with the performance of your video card, especially if you're running a heavy
game like Rainbow Six Siege. It will generate screen viewing issues like intermittently switching your game screen between your desktop environment.

For now, restart your game and do not press ALT+TAB while playing. This will allow your video card to dedicate its graphics performance on the game only instead of your desktop environment.

If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.

 

Game Errors because can't press ALT+TAB

Hi,

Thank you for posting your query in Microsoft Community.

I will surely assist you to rectify the issue.

The “Alt+Tab” key is used to toggle between different programs as well as multiple Windows of same program. I suggest you to use “Alt+Enter”
put the game into full screen.

As a work around, I suggest you to adjust the screen resolution for the game in compatible with the monitor resolution and restart the game and check if it helps.

Hope this information helps. Reply to the post with updated status of the issue so that we can assist you further.

 

alt + tab not working

Just found a really cool way to make alt+tab INSTANT!!!

In the launch options write the following: -windowed -noborder





This play exactly the same as fullscreen but now you dont have to wait 30 f*@!ing seconds to alt+tab back in!

Also you don't get the little purple/black checkered effect (only in Source games) from alt+tabbing in fullscreen.
