On Windows 11, Microsoft has —not just for running Linux VMs, but for core security defenses.

Hardware virtualization in Windows 11 offers several benefits, including:

To enable hardware virtualization in Windows 11, you'll need:

This moves virtualization from “resource partitioning” to “cryptographic isolation.”
