October Windows update may prevent turning on Smart App Control
Why it matters for readers: It's a Windows update bug that can stop a security feature from being re-enabled, and Microsoft has shared temporary fixes while it works on a permanent solution.
- After installing KB5127648, some Windows 11 (version 24H2 and later) devices cannot turn on Smart App Control because the option is grayed out.1
- Devices that already have Smart App Control turned on remain protected and are not impacted by the issue.1
- Microsoft has not released a permanent fix yet but published temporary workarounds for enterprise admins using registry edits or group policy changes.1
- The company documented steps that include running elevated Command Prompt commands and restarting the device to restore the toggle.1
