In my case, in Task Scheduler > Microsoft > Windows > WS there are two tasks that report something else than (0x0; which I think is "Success") as 'Last Run Result' and they are:
Sync Licenses: 0800700E
WSTask: 0800710E0
"Surpricingly" I did do, by quickly searching, find any additional info what do those Run Results mean.
Also attached a copy of that Task Scheduler screen for others to compare. Yet, of course, I do not know if these have anything to do with the actual Error in Event viewer.
And yes, I fully agree, that 99,5% of Windows users never bother (or even know / care) about the Event log in general... For me, despite not a developer nor very very advanced user, it's ~bi-weekly habbit. But that's another story ;)
Ramesh.Kumar, how to escallate this to 2nd/3rd level support @ Microsoft?
