Joachim Henze 1bb175b0b5 [0.4.10][WMISVC][SRVSVC][WKSSVC][DHCPSVC][WUAUSERV] Start/Stop behavior 
by partially porting back:
0.4.15-dev-xxx [WMISVC][WUAUSERV] Fix 2 DPRINTs that lack arguments
0.4.13-dev-684-g eab73ad1a4 [SRVSVC] Make the server service stoppable
0.4.13-dev-683-g 4073a8c58d [WKSSVC] Make the workstation service stoppable
0.4.13-dev-680-g eb532bc641 [WMISVC] Accept stop and shutdown commands when the service is running
0.4.12-dev-1063-g 15a828c86d [DHCPCSVC] Eliminate unused code and associated parameters

and revert 0.4.10-dev-558-g 55368bacc8 (#355) [WUAUSERV][WUSA]
on this branch as that Service stub does not even start in releases/0.4.10-0.4.12.
And it doesn't allow any application to run that wouldn't have run before.
Even with those changes the .NET4.5 and Python 3.5 mentioned in that PR don't work yet.
We postpone introduction of WUAUSERV to releases/0.4.13 therefore.
