Wdcsam64.sys driver preventing me from turning on memory integrity

I have the same problem. I do have an external hard drive. Will external hard drive work without driver?

says i need system permission to delete. this is my pc only no one else uses

I am getting same message saying

Failed to delete driver package: One or more devices are presently installed using the specified INF.

How do I get rid of it?

You can download and extract Sysinternals Process Explorer, run it as Admin and then click Find > Find Handle or DLL and search for wdcsam.inf:

Click on all instances of the wdcsam.inf driver as shown above, it will bring you to the process using this driver in the bottom window, and you can right-click > Close Handle for each one:

Once they're closed, you can execute the pnputil /delete-driver oem##.inf command in an elevated Powershell successfully:

You should now be able to turn on Memory Integrity

Just popping in here to inform anyone who has this issue that you don't need to go through a bunch of scary/potentially risky steps to resolve this issue. Just follow these instructions from WD's official site.

I came to this thread several weeks ago after updating to Win 11 and was hesitant to follow any of the advice here because I aggressively avoid going into the command prompt to do anything. After a couple weeks of ignoring the security alert, I finally got around to searching for an official solution from Microsoft or Western Digital. On the WD forums, I found a link that led me to the one I shared above and it doesn't require any command prompt or admin privileges.

I have an old Passport and mine still works just fine after following these steps. Hope this helps! <3
