How to delete legacy drivers that prevent enabling Memory Integrity

Anonymous

I am unable to activate Memory Integrity in Windows 11 due to a few legacy drivers for devices that don't show in Device Manager (even when Show Hidden Devices is enabled), or apps that don't show in add or remove programs. I located them in C:\windows\System32\DriverStore\FileRepository\ but I need SYSTEM permission to delete them, and I can't figure out how to obtain that.

How can I get SYSTEM permission, or is there another (safer) way to remove the drivers (and possibly any associated Registry entries)?

The drivers are:

ssudcdf.sys

ssuddmgr.sys

ssudobex.sys

wdcsam64_prewin8.sys

    That's the problem. There are no devices associated with those drivers. And yes, I have enabled viewing hidden devices. They seem to be remnants that uninstall programs did not properly clean up. Three are Samsung USB drivers, and I no longer have a Samsung device, and the other is a Western Digital driver for pre-Windows 8. The updated WD driver is installed, but I can't get rid of the old one (actually two with the same name just different dates, versions and published names).

    I found Samsung USB drivers online and installed them, then uninstalled hoping it might remove them, but it had no effect. I assume because it installed and uninstalled updated drivers ignoring the old ones.

    It's odd to me that Windows Security didn't start having a problem with these until this week.

    Hi geoear13,

    Click the link below to download a small free utility that does not require installation.

    https://download.sysinternals.com/files/Autorun...

    When the file downloads, unzip it.

    Run Autoruns64 as Administrator

    Select the Drivers Tab in Autoruns

    Can you find those drivers in Autoruns?

    if you can, untick them from that tab

    Then restart (not shut down) your PC and those drivers should not load.

    Hi geoear13,

    I am Dave, I will help you with this.

    Usually the best option to avoid the permissions error, is not to delete those driver files, right click each driver file and choose rename, then add .old to the file name of each of the driver files

    Then restart (not shut down) your PC, that will stop those drivers loading on startup.
