Nothing works in the recovery mode as it cannot back out the update, cannot repair.
One of the update is kb5003399 and I forgot the other one, will have to boot back to the command prompt.
In the command prompt, I can tell it's not showing my 1TB drive, it's in x:/ with very little space.
Also, wusa.exe doesn't exist in that command prompt.
Can anyone help to get my system booting again?

2021-05-07T07:59:33+00:00 I just got this driver from Windows Update and I am on normal channel! (no beta or insider).
I managed to fix it but pressing F8 during boot and I let windows to repair it!
Now in the the event viewer I have: StartupRepair: Uninstall recently installed driver updates. If I go to "View udpate history" / Drivers Updates: Advanced Micro Devices, Inc. - SCSIAdapter - 9.3.0.221 Successfully installed on 07-May-21 ???
I don't even have SCSI devices on my system! ****!
Never let windows update your drivers again, lesson learned!
The setting is inside control panel > system > advanced system settings > hardware > device installation settings.
Just tick disable and your done. Windows update will no longer download any drivers for your devices.

2021-05-07T07:55:03+00:00 Just had this update pushed to me even though I'm not in any preview/insider builds. Ryzen 5900x, x570 motherboard. Same issue as the people above. After rebooting a second or third time it did a automatic repair and it booted to windows with a message that a update was removed. I don't know what MS was thinking pushing this update out.

2021-05-07T07:28:27+00:00 This update seems to be the culprit. What's the solution though? How do I stop it after reinstalling windows.

After reboot - inaccessible boot device.
Win install USB and fix startup (twice) resolved the issue.

Can somebody explain to me WHY MICROSOFT doesn't remove this driver Micro Device 9.3.0.221 from their update list after so many votes !!!!.
