A standard user does not have the ability to start, stop or change the configuration within any service. This article will step through the process to create a policy to allow this.
Create a new "New Executable Policy"
Select "Use combo rule (advanced)" and click NEXT
Select "Apply command-line arguments", leaving everything else as-is and click NEXT
Under Path Condition, click Add -> Add file ...
In the Path field, type in "*\mmc.exe" (no "") and click OK
Click on Command-line Arguments, select "Strict equality", under Arguments type in the exact path to services.msc (*C:\Windows\system32\services.msc*) and click NEXT
Ensure "Run with elevated privileges" is selected and click NEXT
Note: Users will not acquire this new GPO until Group Policy is refreshed on the user's computer either through automatic or manual means.
