Error 0X800f0922 when installing Windows update KB5012170

i solved it

my system drive is MBR not GPT, the patch KB5012170 is about UEFI, so if you want to update this patch you must change sys drive to GPT

but there is another problem happenned,

my 4k monitor cant show graphic,only 1080P monitor can work same graphic card same port (DP)

So, thank you all for the replies. I have already hidden the update with wushowhide but my opinion is that it is not serious of microsoft to force users to do this manual action, it should be microsoft to manages the case because a user cannot know if the lack of an update can compromise your System.

Just when I was at a loss, I thought if I could update the motherboard bios and system device drivers to solve this problem, so I updated the motherboard bios, motherboard chipset drivers, and various sound Bluetooth wired wireless network card usb drivers, etc., only I didn't update the graphics card driver bios, when I changed to a 4k monitor (DP), it was still dark

I had no choice but to unplug the power cord of the monitor and plug it in again. A miracle happened, and the monitor returned to its normal state. Recalling that I plugged in and unplugged the DP cable, HDMI cable, USB extension cable, and pressed the monitor switch, but nothing happened. unplug the power cord

At this point, the problem that the patch cannot be installed and the subsequent black screen event of the monitor have finally been solved, and the body and mind are exhausted.

For now I hide the patch with wushowhide.diagcab.
