Perhaps the next quickest and easiest fix is to ensure your PC is fully updated. Sometimes an update is the issue. Some users reported problems with Smart App Control being greyed out after the update KB5007651. The feature is also being rolled out gradually to different users and regions.

To ensure this isn’t the case, head to “Windows Updates” in “Settings” (Win + I) and click the “Check for updates” button.

Enable Smart App Control via the Registry

If Smart App Control is greyed out, you can use the Registry to check its status. On qualified systems, changing the value can update the mode, but if it doesn’t meet Microsoft’s requirements (such as upgraded installations), Windows may ignore or reset the change. For Smart App Control, how to turn on is a matter of changing registry value data.

A word of caution: editing the Registry incorrectly can result in system instability, so follow the steps carefully.

Step 1. Open the “Run” dialog (Win + R) and type “regedit” into the box, then press Ctrl + Shift + Enter to run it as Admin.

Step 2. In the Registry Editor, navigate to the following path at the top of the window: “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CI\Policy.” You can just copy and paste in.

Step 5. Restart your PC and reopen Windows Security to see whether Smart App Control is available.

Note: If Smart App Control remains greyed out, your installation may not be able to enable it. Microsoft requires a clean installation (or “Reset this PC”) of Windows 11 for Smart App Control to be activated.
