I am having problems with the new Smart App Control feature in Windows 11 Home (windows build 22621).

After activating some Windows Features, Smart App started popping up with warnings that the .NET Runtime Optimization Service has been blocked and has stopped it from loading. Also DLLs that I think are signed by Microsoft (mscorlib.dll, System.dll, System.Net.dll, etc) are all getting blocked and keeps giving these annoying notifications until I switched it off.

It is also blocking WSL, an app that is offered by Microsoft in their app store is being blocked. Also, other Linux Distro apps are being blocked.

How do I configure Smart App Control to run .NET Runtime Optimization Service and WSL properly?

    Hello,

    Since in this case, the feature is blocking different required elements, the solution would be to disable Smart App following the next steps:

    1.Open Windows Security.

    2.Click/tap on App & browser control in the left pane, and click/tap on the Smart App Control settings link on the right side. (see screenshot below)

    3.Select On or Off for what you want.
