Here is the Windows 11 Xbox GameBar Fix That I have finally found the solution for! (I don't guarentee this will 100% work for everyone but it hopefully will work for the most part) }
So there are 2 different methods you can attempt (I recommend doing both of these to be sure that you get the necessary files and activate GameDVR Properly. Keep in mind I am no expert at this, I am just a random guy on the internet who found a solution for this).
Alright Lets Get into The Methods
Method 1 : Download and Install the Standalone Windows Update (It is Windows 10 but it works for 11 too)
- Go to https://www.microsoft.com/en-us/download/details.aspx?id=48231
- Scroll down and find the Orange download button and click it
- Select the Microsoft-Windows-MediaFeaturePack-OOB-Package_x64.msu and click on Next
- After it does download, go to your downloads folder and run it.
- After it is completed, Restart your PC.
Method 2 : Regedit Entry Changes
- Go to the Windows Search Bar and type in Regedit OR click on Windows Key + R and Type Regedit and click on Ok
- We are going to check HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\ (copy and paste) Choose "GameDVR" from the right panel and change "AllowGameDVR" to 1. If there isn't one: Right click the empty area, choose "New" and then "Key" Name it to GameDVR. It makes a new key / "folder". Inside the GameDVR key, right click on the empty area again, click "New" and choose "DWORD". Name it to "AllowGameDVR". Double click it and set it to 1.
- Go to HKEY_CURRENT_USER\System\GameConfigStore (copy and paste) Double click "GameDVR_Enabled" and change it to 1.
- Go to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR Double click on AppCaptureEnabled and set it to 1.
- Restart your computer.
This Worked for me and I hope it will work for you! Feel free to ask me any questions :)
