Cumulative Updates keep saying "We couldn't complete the updates" "Undoing"

Anyone noticed how Cumulative Updates in Big Fix for June, July and August are all failing and rollling back or “undoing” after the reboot? This is driving us crazy, anyone have a resolution?

Specifically KB43438884, KB4343889, KB4343885, KB4338827.

It’s definitely not happening for everyone, they went fine for me.

Check \Windows\Logs\CBS\cbs.log to see whether you can determine the failure cause.

In my environment, at one point in the past we had a holdover policy that prevented USB drive installation by removing SYSTEM permissions for usbstor.inf that caused servicing to fail when the updates attempted to overwrite the driver file.

Hi Jason, is there anything to fix this? Particularly, is there a powershell script we can run during the pre-Action to take control of this driver file and grant access?

Thanks,

You’ve need to check the CBS.log to see whether you’re even having the same problem.

I’m sure a PowerShell script could reset the permissions now; when I encountered this, maybe 10 years ago, I used “takeown” and “cacls” to take ownership and reset permissions on the file.
