Microsoft Update KB2952664, Compatibility update for upgrading Windows 7 installs - among other files -
invagent.dll iologmsg.dll
... Which I didn't catch, prior to the upgrade. I mean, I knew that there are, there will be, some Windows 10 -prep- updates and such - but, maybe I had expected them to be better marked, or something.
So, went to teh Control Panel\All Control Panel Items\Windows Update\View update history, Installed Updates and removed it from there. Rebooted, Windows fiinshed (un)installing updates; that dialog completed (prior to loading the Explorer, Desktop).
The problem is that the files did NOT get removed. IDK, does the Task still run?! o.0
^^ What is there (left) to do?.. How to go about removing, rooting-out the Windows 10 experience which I did not ask for (omg). Ofc., 99% I'll be installing Windows 10 - but, from an ISO (or something, right?.. 
) once it comes out. In the mean time, what are we to do; because, I'm willing to be that there are /will be tons of people with this *problem*
?! Any help, please, thoughts?!
Edit: Oh, yea, almost forgot... There is another one (update), totally unnecessary, similar to this (KB3068708)!!
