I have a driver that is prohibiting me from turning on memory integrity. The driver is wdcsam64.sys. How do I turn it off or delete so I can turn on memory integrity?

    Found a simple solution for Windows 11:

    1. Open File Explorer and go to OS (Local Disk C)
    2. Type in search bar wdcsam64.sys
    3. Wait for full search to end.
    4. Choose and delete the item with the description similar to "Wdcsam64.sys"
    5. Do a restart.
    6. Go to Core Isolation and activated

    I have 5 items similar to wdcsam64.sys there. Do I delete ALL of them? I tried to delete the pre-win8 sys file but I too got the no can do unless system administrator message, which I am. I give up. windows says security is fine on the computer and I have other security so I officially give up on this.

    This particular solution worked very well for Windows 11. Easy and no side effects (yet!)

    If you don't need this driver (for operating an external Western Digital USB-drive), you may delete it:

    Right-click on Start, then click Windows Powershell (Administrator). In the PowerShell window, enter and run the following command:

    pnputil /delete-driver oem**##**.inf

    Replace ## with the number that appears on the appropriate line of the Windows security message.

    You should now be able to activate the memory integrity option.

    I noticed this same issue today when installing some updates on my computer as well. I do use the external hard drive so that answers the my question. Thanks!

    Now to show my ignorance even further: If I delete it the way you described above and then attempt to utilize the hard drive, will that driver then need to be reinstalled each time I plug it into my laptop? I feel confident the answer is "yes." The bottom-line question is what security is not being provided to my laptop because of this and are there any workarounds?

    Thanks!
