Dear w01dnick
Thank you for posting in the Microsoft community.
I am very sorry to learn that you are suddenly experiencing a black screen during gameplay, driver updates and other complications.
Regarding your issue, I will dismantle this problem step by step and provide you with some solutions.
Problems with the Windows Update mechanism
Although you have selected “Hide for now”, Windows Update sometimes still downloads and installs certain critical updates (e.g. driver updates) automatically in the background, especially when the system considers these updates as “important”.
During gameplay, Windows Focus Assist usually delays notification, but does not prevent updates from being installed in the background. 2.
Graphics Card Driver Conflicts
During gameplay, graphics card resources are highly utilized. If Windows Update tries to install a new graphics card driver, it may cause the driver to be uninstalled or reloaded, which may result in resolution switching, stuttering, or even a black screen.
The updated driver may not be compatible with the existing system configuration or hardware, causing the system to fail to start normally after reboot.
Here we share a registry solution which will define Windows Update and after setting it, Windows Update will be triggered only when you click Auto Update.
Press WIN+R and type:
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" /v NoAutoUpdate /t REG_DWORD /d 1 /f
Disclaimer: Modifying the registry or workgroups is usually geared towards advanced users, administrators, and IT professionals, and it can help fix some problems, however, improper registry modifications can cause serious problems. Therefore, please make sure to strictly follow the steps below. For further protection, make a backup of the registry before modifying it.
