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.

Cannot delete this driver
I get an error message that says the driver is in use by one or more devices and will not delete.
Hi Robert;
Three things to try:
1: reboot
2: reboot in safe mode
3: uninstall any programs / addins you are not using - many people leave software intalled for old scanners, printers, cameras... and that really expands your attack surface
Let us know how that goes and thanks for checking in with us.
I have tried to elminate the driver with pnputil /delete-driver oem97.inf in safe mode. I can't delete
I searched the oem97.inf file in C:\windows\INF and find oem97.inf and oem97.pnf. I renamed the two files to oem97.inf.bak and oem97.pnf.bak. I restarted in normal mode but I cant delete with pnputil /delete-driver oem97.inf, I continue obtaining the error message.
"Error al eliminar el paquete de controladores: Actualmente están instalados uno o más dispositivos que utilizan el archivo INF especificado."
Im having this issue aswell and I just build this pc and installed the drivers, got any tips?
