How to Turn Off Virtualization-Based Security (Memory Integrity)

If you encounter the Hyper-V detected issue even after you disable Hyper-V, try to disable the Memory integrity feature in Windows Security.

The Memory integrity feature is part of Core Isolation. It helps prevent threat actors from accessing and infecting high-security processes using malicious code.

By default, Windows disables the Memory integrity feature to avoid conflict with apps and device drivers due to incompatibility issues. This can also cause issues with third-party virtualization tools and programs that need to access your system's virtualization hardware.

To turn off Memory integrity in Windows Security:

1. Press Win + I to open the Settings app.

2. In the left panel, click on the Privacy & security tab or click Update & Security if you on Windows 10.

Windows 11

Windows 10

3. Next, click on Windows Security.

4. Under the Protection areas section, click on Device security

Windows 11

Windows 10

5. Next, click on Core isolation details under the Core isolation section.

6. Toggle the switch under Memory integrity to turn it Off.

7. Restart your PC to apply the changes.
