Microsoft uses virtualization in Windows 11 for scenarios including Hypervisor-protected code integrity (HVCI), also called Memory Integrity, and the Virtual Machine Platform (VMP).

Memory Integrity helps prevent attackers from injecting their own malicious code and helps ensure that all drivers loaded onto the OS are signed and trustworthy. It will be enabled by default on all new Windows 11 devices.
