I greet the community. I am asking for your help to solve a problem which is perhaps not directly, but in some way, related to WSA.
Since a couple of weeks or so I have to deal with a very strange malfunction on one of the three machines of my network (all of them with Windows 8.1). It's a HP laptop 250, which I use intensively and normally with an additional screen to have a large display with vertical development.
Well, what happens, in seemingly random circumstances, it's that all of a sudden I cannot move or resize any window! This applies to Explorer windows, as well as for those of the browser, or of any other application. I also noticed that, during this malfunction, the utility for screen capture does not capture anything.
What's even stranger is that the malfunction may lasts several minutes, even 15' or 20 ', but then it ends and the PC turns back to work properly!
While I have the issue the "Task Manager" does not detect any process that could arouse suspicion, and the use of the various resources (CPU, disk, etc.) is within normal limits.
The PC is configured for installing updates manually, I apply them regularly, and so far I preferred to install optional updates as well. In theory, the problem could have been introduced by some "buggy" update, but, in that case we would then be of course many to complain of it.
However I saw that others in the past have complained about a similar problem, but the causes and remedies are not clear: http://www.eightforums.com/general-support/29793-cannot-move-resize-windows-drag-mouse-slow-response.html. A “magical” self-restoring is also reported!
A possible cause can be some sort of corruption of the OS, therefore I ran "sfc /scannow", also in safe mode.
The utility said "impossible to repair some damaged files", but going to see CBS.log, this concerns with Amd64CNBJ2530.DPB of prncacla.inf, that according to what we read here: http://answers.microsoft.com/en-us/windows/forum/windows_8-performance/hash-mismatch/08ef49a6-84e8-47ad-bd69-48b829d495c9, should not be a serious problem.
However, after running "sfc /scannow", it seems that nothing has changed, since the problem has come back to me this morning, but since then the machine (without having rebooted it) is operating normally!
Another possibility is that all this is due to a virus, but nothing has been detected by WSA. To be more certain I also ran a deep scan with Housecall, which detected nothing abnormal too.
At this point I really don't know what to do and I hope for your help.
You may consider that I already asked to the local MS community here, and our local guru replied as you may read here (perhaps with the help of the Google translator): http://answers.microsoft.com/it-it/windows/forum/windows8_1-performance/impossibile-spostare-o-ridimensionare-finestre/98aa845d-f7f0-49fa-a557-4ace5e9d0309?tm=1446653149653
He substantially said to follow these steps for a “clean” start of the OS and for correcting possible corrupted files:
http://answers.microsoft.com/it-it/windows/wiki/windows8_1-performance/avvio-pulito-per-windows-8-81-10/34152d49-1b32-4f01-b559-d8894a9627c6
He strongly recommends, as the first step, of completely removing any AV of third parties!
To say the truth the guy IMHO has somewhat radical ideas, as according to him third parties AV's (and added functionality), ruin the system modules!
For WSA the steps to follow are described in this page, right?

It looks like somewhat outdated however (no mention of Win 8.1 or 10!), but I hope it's still valid.
In any case what do you think of this issue and of the proposed solution?
Do you have alternative ideas?
