Microsoft to Enable Memory Integrity by Default, Affecting Gaming Performance

In October 2026, Microsoft will automatically enable Memory Integrity in Windows 11 for eligible devices, enhancing security by ensuring only trusted kernel-mode code runs. This feature, part of Virtualization-based Security (VBS), is designed to prevent malware from exploiting vulnerabilities in kernel drivers. While it significantly boosts security, users may experience reduced gaming performance, particularly those utilizing undervolting software. The rollout will not affect devices where Memory Integrity has already been disabled. Users can check their settings via Windows Security. The change is part of a broader strategy to improve system security amidst increasing threats. Affected systems include those with Intel 8th generation or newer, AMD Zen 2, or Qualcomm Snapdragon 8180 processors. The update will be applied automatically unless users have previously disabled the feature.

Key Points: • Memory Integrity will be enabled by default in Windows 11 starting October 2026. • The feature enhances security but may reduce gaming performance for some users. • Eligible devices include those with Intel 8th gen or newer, AMD Zen 2, or Qualcomm Snapdragon 8180.
