Microsoft: October Windows update may break Smart App Control

Microsoft has identified a problem with its October Windows 11 security update that prevents some users from enabling Smart App Control, a security feature designed to block potentially harmful applications. The issue affects devices running Windows 11 version 24H2 and later, where the Smart App Control option becomes grayed out and cannot be activated if it was previously disabled. Devices that already have Smart App Control turned on are not impacted by this update.

While Microsoft develops a permanent solution, the company has provided temporary workarounds for IT administrators managing enterprise devices. Users can restore the feature by running specific command prompt commands that modify the system registry, or administrators can deploy group policy settings to re-enable Smart App Control on affected computers. This update represents one of several recent Windows issues Microsoft has addressed, including problems with Remote Desktop access and VPN connections.
