Memory Integrity switched off because of driver

Anonymous

MS Windows Home 10.0.2200 Build 2200

Windows Security showed ‘memory integrity is off’ because of ‘incompatible drivers.’ The driver is wdcsam64.sys (Driver version 1.0.7.2, WD External Storage. No other info given).

There were other incompatible drivers but I successfully uninstalled them using Powershell. Unfortunately wdcsam64.sys does not show up after the Powershell command of pnputil /enum-drivers. So I’m unable to find the oem*inf attribution. So I can’t remove it using Powershell.

I have uninstalled the WD driver in Device manager. The problem persists.

A search reveals the file in ``C:\Windows``\System32\drivers. However I’m not in the habit of just deleting drivers here for obvious reasons. Please advise if it is in fact safe to do so.

Have updated Windows. Fully up to date.

So at the moment I’m unable to remove or update this driver, and therefore cannot turn memory integrity on in Windows Security. You can see that this is a non-trivial security issue that is way disproportional to the everyday action of plugging in an external drive.

In summary:- Windows memory integrity is off.

- unable to turn it on

- cannot update driver

- cannot remove it because it doesn’t show up with the pnputil /enum-drivers command on Powershell.

- reluctant just to delete it from %system32\drivers

Any advice or suggestions appreciated. Thank you.

Hi Stephen,

Download Autoruns from the Microsoft Sysinternals site, and run it as administrator.

In the search box in Autoruns, type the driver file name "wdcsam64".

If wdcsam64.sys appears in the list, right-click and choose Delete.

Hi Ramesh,

Once again Microsoft has stepped up. After a fairly lengthy 'chat' we managed to resolve the issue.

Thanks for your support.

Hi Arthur,

From an Admin CMD prompt window, run:

pnputil /delete-driver oem25.inf /uninstall

That should help.
This helped! Thanks @Ramesh

Dear fellow community members,
i just had the same problems.

Thanks a lot @Ramesh Srinivasan

Your prompt command line solution has worked for me, too.
```
pnputil /delete-driver oem25.inf /uninstall
```
Careful: in my case, it was oem74.inf

Please be aware: I had to run a registry cleaner afterwards before it finally worked.

Before, I had just tried to re-start the computer, but that did not work.

After running Ccleaner and cleaning the registry, and then new start, it finally worked.

It sucks that Windows does not prevent this incompatible driver from getting installed to begin with!

And it sucks that Western Digital creates a driver that interferes with Windows. Are they asleep in their product testing department?!
