Personally I think it's a great shame that Microsoft have lacked giving adequate support and not just put their hands up with this issue rather than people trying different things and ideas and yet it is a Windows 8.1 problem.
I know that various mods and engineers are a great help a lot of the time but at times rather than go through the "try this/try that" script practically saying that it is "your" PC or settings are at fault it would be nice if Microsoft actually admitted that there is an issue their end rather than advising users to just randomly change settings for the sake of it.
I had XP and was more than happy with that however things change and Windows 8 was my next port of call which is an awful OS for a PC user however at least it worked for what I required. To have Windows update constantly advise me to upgrade to 8.1 then spend the next week trying to sort out issues after that install is nothing short of a disgrace quite frankly. Mind you nothing comes for free so I guess I should have heeded the warning signs right there!!
Considering the lack of support on this **** up the temptation to contact a National newspaper is definitely there and I do wonder if some bad press may get MS to get this sorted.
