Set-Service -Status Stopped not only prevents stopping services that other services depend on (.DependentServices), but, curiously, also services that themselves depend on others (.ServicesDependedOn.

For instance, the wuauserv service has no dependents, but itself depends on the rpcss service.

As an aside: Set-Service -Status Stopped lacks a -Force switch that would allow it to stop dependent services too, the way Stop-Service offers.

Steps to reproduce

Set-Service -Status Stopped wuauserv

Expected behavior

Given that the service has no dependents, it should be stopped.

Actual behavior

The following error occurs:

Set-Service : Cannot stop service 'Windows Update (wuauserv)' because it is dependent on other services.
...

That the service depends on other services shouldn't prevent its stopping.
