Disable Windows Memory Integrity

Disabling Windows Memory Integrity is simple enough, and necessary if you're running a VM within a VM^[1] and you have a few ways of getting there.

1. Settings
   1. Open Settings and select "Privacy & security" in the left column
   2. Choose "Device Security", then select "Core isolation details"
   3. Toggle-off the option below "Memory integrity"
2. Windows Defender
   1. Click on "Windows Defender" in the system tray
   2. Choose "Device Security", then select "Core isolation details"
   3. Toggle-off the option below "Memory integrity"

But once you're done and want to re-enable Memory Integrity, you might get an error about drivers that are incompatible with it. It's frankly a little absurd that often these drivers have been on the system since the computer was imaged with Windows... wtf?

Anyway, here's how I solved the problem quickly and easily, without having to download anything dangerous.

NOTE: The screenshots below were taken from this video by TechMens Land, because by the time I realized I should document my process, I'd solved the problem.

1. Click on the "Review incompatible drivers" link from the "Memory Integrity" management page.
2. Click on the listed drivers to expand their details.
   1. Under details, you should see information like Import date, driver date, etc., but we care about the "Published name"^[2]
   2. NOTE: while investigating, you will find the same driver listed as example.sys,^[3] example.inf, and oem420.inf; this is normal.
      1. example.sys is the actual driver itself which contains the critical information
      2. example.inf contains the information that identifies it to the system and describes the driver
      3. oem420.inf is the device specific name for the driver, based on the order of installation.
         1. This helps avoid problems if there are two drivers named example.inf but published by two different entities and that are otherwise unrelated
3. Run Powershell or CMD as an administrator, and use pnputil to uninstall and remove the offending drivers, identifying them by their Published name (e.g., oem420.inf)
   1. pnputil /delete-driver <Published Name> /uninstall /force
4. Once you remove the incompatible drivers, go back to the "Core Isolation" page and ​select "Scan Again"
   1. Memory Integrity should be re-enabled, and you just need to reboot to finish applying the changes.
