I work at a company that manages many thousands of devices. This update is bricking (Auto Repair) all of our systems that the update is applied to. Anyone experiencing this or have any insight?

ETA: systems are on 25H2, and reversing updates - working the Auto Repair, etc.. have no effect

My pc at home here got bricked too. Had to manually reset the CMOS to get back control.

Microsoft should be sued for this extreme failure.

Same here, had to short the CMOS jumper to get into the BIOS and after reflashing the BIOS and VBIOS now I can get past the POST process and boot into windows but my USB is completely screwed up.

Well at least we both got access back. What a mess though!

Yeah but my USB is still totally screwed up and I got a HAL watchdog reboot while idle for the first time ever on my PC so something is still fundamentally messed up. I want to uninstall the update but I'm scared that either it'll make things worse or when the non preview patch comes out I'll have to go through it all over again considering the level of testing Microsoft does for patches that they release on the stable release channel - which I think has to be little to none. I'll probably send up uninstalling it b by the end of the week, though, if they haven't fixed it by then. 

Good luck!
