Re: Can't disable Xbox Game Bar popup

Open Windows Settings, go to Gaming → Xbox Game Bar, and turn off the toggle switch. Then, use regedit to open the Registry Editor, navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\GameDVR， set the values of AppCaptureEnabledand GameDVR_Enabled to 0, and restart your computer for the changes to take effect.
