            Bug ID: 53460
           Summary: advapi32:service regularly fails on Windows when
                    services stop / start
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: advapi32
          Assignee: wine-bugs(a)winehq.org
          Reporter: fgouget(a)codeweavers.com

advapi32:service regularly fails on Windows when services stop / start.
Because this may happen at any time the failures can take many forms:

service.c:1729: Test failed: Expected a process id for this running service
(sppsvc)
service.c:1746: Test failed: Active services mismatch 4294967295
service.c:1747: Test failed: Inactive services mismatch 1
or
service.c:1729: Test failed: Expected a process id for this running service
(SgrmBroker)
...

or

service.c:1746: Test failed: Active services mismatch 1
service.c:1747: Test failed: Inactive services mismatch 4294967295

or

service.c:1342: Test failed: Expected 114 services to be returned
service.c:1612: Test failed: Expected the same number of service from this
function

or

service.c:1729: Test failed: Expected a process id for this running service
(edgeupdate)
or
service.c:1729: Test failed: Expected a process id for this running service
(MapsBroker)
or
service.c:1729: Test failed: Expected a process id for this running service
(W32Time)
or
service.c:1729: Test failed: Expected a process id for this running service
(BITS)
or
service.c:1729: Test failed: Expected a process id for this running service
(DoSvc)

https://test.winehq.org/data/patterns.html#advapi32:service

The service names give a hint as to what happened:
* An Edge update got triggered: edgeupdate, probably BITS too.
* A time synchronization happened: W32Time.
* Some application caused the on-demand "Downloaded Maps Broker" service to
start: MapsBroker.
* Something caused Windows Update Delivery Optimization to start (despite it
being disabled in the settings): DoSvc.
* The 'System Guard Runtime Monitor Broker Service' got started for some
reason: SgrmBroker.
* The 'Microsoft Software Protection Platform Service' which is involved in the
license checking got started: sppsvc.

So I don't think it would be reasonable to disable all these services. We would
still likely have a steady trickle of other services causing trouble, and we'd
have the problem again when a new Windows version introduces another service.

Instead advapi32:service should be more resilient. That may mean accepting
small variations in the number of running services, or checking that a service
is still running before complaining that it does not have a pid.
