Colif :
if you were stuck on this version, it wouldn't be forever. Just wait 8 or so months and get newer version of win 10, make an ISO using media creation tool and fresh install then. if so many having problem then another update likely be pushed out to fix this one.
you could post on windows forums as they might have a solution or post a question on http://www.tenforums.com/windows-updates-activation/ and see if they have any better ideas (can link to this if you want, save them doubling up on ideas)
I'll consider it. Never signed up to Tenforums before.
EDIT:
OK get this, something very weird happened:
I've started by deleting the content within: C:\Windows\SoftwareDistribution\Download.
Then, I launched ResetWUEng (Windows Update Reset Tool) > Yes > 2: Reset WU components.
After a while the process was complete.
I've opened Windows Update, and found that the history was all erased and Windows Update was reset to its original state. Make sense so far.
So - I ran Windows Update and waited, at about 35% installation of the cumulative update KB3197954 -my PC crashed.
-It happens sometimes, this is my old work-station PC (and minor gaming) with some power-out issues (that I was unable to fix for well over a year now).
Anyway, after the PC reboots by itself, Windows boots up into a red loading screen, saying something like: "Getting your PC/Updates ready". In other words, it was preparing & finalizing installation of downloaded updates (!!!!).
At 30% it restarted automatically, loaded Windows up, and then advanced all the way to 100%. Windows finished booting up.
Once it was done, I opened Windows Update and although it said something along the lines of: "failed to install updates since the computer shut down" - I've checked the Update History and found this line:
Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3197954)
WHAT..... THE... HELL?
My theory is, that - remember when I installed the Update from Windows Update Catalog? WU completed the process but said: "was unable to not install the following update"...
Maybe it HAD actually installed it, but in order to finish the process, a reboot was in order?
Or maybe, the actions I took with WU RESET had put things into motion ? A string of actions perhaps (DSIM, WU RESET etc) ? I do not know.
It could also be a corrupted update due to the sudden crash and shutdown...
EDIT x2: I just tried to run the patch I downloaded from Windows Update Catalog (kb3197954) and it said: "KB3197954 was already installed by Windows Update".
EDIT X3: Running Windows update again, it says:
Your device is up to date. Last checked: Today, 12:15 AM
Could it be?! HOLY @#$%?*!
Such a lust for revenge? WHOOOOOOOOOOO?
