Windows 10: GameBar Can't Programmatically Disable HDR Notifications

Hi I am trying to programtically check through windows registry "Hide HDR Notifications on this device". I looked under these registry paths before and after the change rebooting regedit each time it got changed. I also diffed the entire HCKU before and after revealing nothing changed that had anything to do with the xbox game bar."HKEY_CURRENT_USER\Software\Microsoft\GameBar HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR HKEY_CURRENT_USER\System\GameConfigStore"

:)

 

Turning HDR on/off programmatically

I need way to turn HDR on/off programmatically instead of using Windows Display Settings (https://support.microsoft.com/en-gb/help/4040263/windows-10-hdr-advanced-color-settings).

Is there a COM object or API that I can call or use to turn HDR on/off in my application code?

Thanks.

 

Gamebar process problem

Yeah, Like many people here have commented I have disabled everything in relation to Windows Game mode, gamedvr and gamebar in the settings menu. When that failed to fix the issue, I disabled everything in the registry in relation to game mode, gamedvr and
gamebar. That stupid gamebar presence process was still there. Then I used powershell to remove the xbox app. Still there. It only started doing this today. Please get rid of this crap and give me back control over what runs on my own computer.

Thanks.

 

Gamebar process problem

Hi,

The Gamebar Presence Writer is automatically enabled on your computer if you opened the Game bar and play a game. This process allows you to record video clips from your games.

If you are playing a game and you want to disable the Gamebar Presence Writer, follow the steps below:

• Click Start, and then type Task Manager in the search box.
• Select Task Manager.
• Under Processes, look for Gamebar Presence Writer, and then press the
  End task button.

To disable Game bar, here are the steps:

• Launch Xbox app, and then go to Settings
  
  .
• Click Game DVR.
• Turn off Record game clips and screenshots using Game DVR.
