Windows 10: Locking out of fullscreen games

Hi,

Sometimes while playing games in fullscreen (like Rainbow Six Siege or League of Legends), after sending a chat message or after opening the chat window, I get locked out of the game. Meaning I can't interact with anything in the game, like menues, moving or really anything. I can still see what is happening, but I have no idea how I got the problem, so I can't recreate it on purpose.

Any help is welcome, thanks.

Windows 10 1709 (16299.309) has somehow disabled 'Fullscreen' in games.

I recently updated to 1709 and have found that games no longer have access to fullscreen mode.

Most games force me directly to Windowed mode, and no longer list Fullscreen in the enum. Some games still allow windowed fullscreen. Games that list the standard Fullscreen typically crash or post an error when I swap to that mode.

The only thing that has changed on my system is my OS version, and I've been using an otherwise identical setup for gaming for years.

Since updating windows, I updated my video drivers, which resolved nothing. Sadly I just passed my 1 week window to undo the windows 'upgrade'.

Hi Syrius,



Thank you for writing to Microsoft Community Forums.



To have clarity on this issue and guide you accordingly, kindly help us with the following information.

• Is the issue specific to a game or does it occur on all the games?
  
• Is the issue specific to only games or does it occur while playing full screen videos?
  

If the issue occurs while playing videos in full screen, you may want to uninstall and reinstall the video card drivers to see if it helps.

• Right click the Windows icon on the taskbar and choose
  Device manager.
  
• Expand Display Adapters, right click on your video card driver and choose
  Uninstall.
  
• Check the box Delete the driver software for this device.
  
• Reboot the machine for Windows to automatically reinstall the drivers.
  

If the issue is specific to games, it could be a compatibility issue. I suggest you to refer to the article
Make older programs compatible with this version of Windows and run the games
in compatibility mode to see if it helps.



If the issue persists, it could be due to the full screen optimization. As you’ve already updated the drivers, I would suggest you to disable the same and check if it works.

• Open Settings and go to System > Display.
  
• On the right pane, click on the Advanced graphics settings
  hyperlink.
  
• Uncheck Enable fullscreen optimizations
  and exit Settings.
  
• Restart the machine and see if the issue persists.
  

Let us know how it goes.

Regards,
