If you are trying to tighten up your security by adding Virtualization-Based Security (aka VBS) to your Windows 11 you might find this error:
Core Isolation Memory Integrity
Incompatible Drivers WDCSAM64_PREWIN8.SYS
Driver date: 11/29/2017Driver version: 1.2.0.0Published name: oem26.inf
This is an old driver that ships with both Windows 10 and Windows 11 and very few people need it. In fact we have never run into a situation of any machine using WDCSAM64_PREWIN8.SYS .
Fortunately, it is very easy to remove:
You do NOT need a reboot so you can immediately retry to enable CORE ISOLATION and you should see a prompt to reboot once Core Isolation > Memory Integrity is turned ON.

Awesome - finally a fix that actually works!!
What you are suggesting with /force is possibly disabling a device driver for a HARD DRIVE. In a running windows session, this is not something you should do without first investigating which devices are using the driver.
Thank you!! I used cmd as habit then later realized had to use terminal. Now it is all resolved
I tried this to remove rcblan.sys, and I got the message, "failed to delete driver package: The system cannot find the path specified." Help appreciated.
Thanks, it's working
Using /force as described by Robert Hadley 9/7/2022 removed the driver when "one or more devices are presently installed using the specified INF." No adverse effects except that the new Memory Integrity setting blocked a Gigabyte driver.

got this error -

I have the same issue. I don't know the answer.
I went through the procedures to delete the files shown as incompatible. However, when I entered the OEM file to delete it, it said it failed and that access was denied. Is this because my laptop is a company laptop, and they may not allow me to delete these things? Any ideas?
run as admin
found elsewhere, when adding the command pnputil /delete-driver oem.inf, if it doesn't work, change it to pnputil /delete-driver oem.inf /force it got rid of the pesky drivers that would not go away.
its really worked for me pnputil /delete-driver oem15.inf /force
thank you so much
Worked for me too perfectly. Had 2 WD drivers, one deleted, other was refusing to delete. / force did it for me. Many Thanks!!!
Perfect answer! Thank you!!!
Thanks, it worked!
