Microsoft is implementing several updates for Windows 11. In August 2026, the company began testing an adaptive hibernate policy for laptops via the Windows Insider program. This update adjusts Modern Standby behavior based on battery levels, switching to a deep-sleep state when charge falls below 10% to minimize power drain.

In September 2026, Microsoft announced that starting in October 2026, it will automatically enable Memory Integrity protection—also known as Hypervisor-Protected Code Integrity (HVCI)—on Windows 11 devices. This security feature uses the Windows hypervisor to isolate code integrity checks for kernel-mode code. The rollout will involve system evaluations of hardware and drivers to ensure compatibility, though users who have manually disabled the feature through administrator policies will not be affected.
