Windows 10 Fall Creators Update with unsigned mmc.exe

After upgrading to Windows 10 Fall Creators Update (Version: 1709, OS Build: 16299.64) mmc.exe is not recognized as a signed file.

1. I tried to execute it from cmd as administrator and worked:

   
   

   c:\Windows\System32\mmc.exe c:\Windows\System32\services.msc




2. When I'm trying to start the Services app (that is using mmc.exe).
   

   
   

   I get the following error

   
   

   

The file indeed looks like unsigned (but I didn't checked on previous releases). Comparatively other executable file has the tab Digital Signature.

3. I tried to fix everything by running with no success:

   
   

   Dism /Online /Cleanup-Image /RestoreHealth
   sfc /scannow

There is any solution to fix this?
