Virtualization Based Security

Microsoft to turn on VBS memory integrity by default in Windows 11 next October

Microsoft confirmed that starting in October 2026, memory integrity protection built on Virtualization-based Security will be switched on by default for eligible Windows 11 PCs. The feature runs Windows as a guest OS under Hyper-V to isolate the kernel from tampering, but Microsoft has previously acknowledged it can hurt gaming performance. Organizations will retain the ability to disable it, though the default posture is shifting toward security-first.

Microsoft to auto-enable Windows 11 memory integrity security feature next month

Microsoft will start rolling out updates that automatically turn on memory integrity and Virtualization-based Security on eligible Windows 11 devices, aiming to make the OS secure by default. The kernel-level protection blocks untrusted drivers and code but can reduce gaming frame rates, especially on older CPUs. Devices where users previously disabled the feature will not have it re-enabled automatically.
