KB5012170 fails with the error code 0x800f0922 when you try to apply that update on a system that has secure boot turned off.

Just my 0.02$: It's kind of ridiculous seeing these "you can try this solution or that solution" replies, even more so when the suggested solutions are basically lists of every possible way to **try** to solve anything...

"Reset every windows component", really.

Also: those error codes are not exactly helpful.

i have this situation today

im zh-cn windows 10 user

For now I hide the patch with wushowhide.diagcab.

Maybe is because my old pc does not have TPM chip, that's why it showed "install error"?

I have this same issue. Windows 365 Windows 11 machine.

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)

This update will not install on all systems. If your firmware is one of those, MS is leaving you to resolve with your hardware manufacturer. A security update doomed to fail. I'm going to disable the update.

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.

Me too - you'd think that would eliminate the "hardware / driver issue" wouldn't you?
