Windows 11 to Enable Security Feature That May Slow Older PCs

Microsoft is set to enable the Memory Integrity protection feature in Windows 11, which will help prevent malware from infecting operating system processes. However, this move may slow down some older PCs.

The feature uses hardware-dependent methods to block malicious code and has been available on eligible devices since the release of Windows 11. But it's only now that Microsoft is expanding its reach to all compatible computers via an October update.

Ahead of this change, users can check if Memory Integrity protection is already active by going to Windows Security > Device Security > Core Isolation Details. If not, they will be prompted to reboot their PC after the feature is enabled.
