Wdcsam64.sys driver preventing me from turning on memory integrity

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?

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

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

I've been reading all of the replies here and also could not delete the files of gain permission to delete them. I finally went to Western Digital's website and they stated that the fix is to download the LATEST software from the site. I followed their steps, and alas, it worked! I guess it removed the wdcsan64.sys file and replaced it with one that allows one to reactivate the memory integrity. I was actually not expecting to work, but it did! Here is a link to the first steps for anyone else who has tried everything:

Memory Integrity Cannot be Enabled for Core Isolation in Windows Security (wd.com)
