My laptop has not been right since Microsoft installed Update 24H2 on 11-25-24.

My laptop has not been right since Microsoft installed Update 24H2 on 11-25-24. The most important thing to me is that my Password manager doesn't launch to sites and install usernames and passwords. I also get a message that driver WCDSAM64.sys didn't load. Evidently this driver is associated with Western Digital USB drives ... which seem to be working fine. which I use for all backups.

RIGHT click on the START button and select WINDOWS TERMINAL (ADMIN)
If you are on Windows 10, select POWERSHELL (ADMIN)

You can then list all of the drivers on your computer using pnputil /enum-drivers

and find the one with WDCSAM64_PREWIN8.SYS or you can just look at the error message.

In my case the driver that needs to go is OEM26.INF

Uninstall the driver using pnputil /delete-driver oem
