Sorry, what happened to the batch script you had in the first post? I can see it's been edited out but am not sure why.
Post7, There is also belarc adviser which gives the product key amongst a whole load of other statistics. I used it once a few years back so I could note down the product key for windows on one of my machines.
Post4, I haven't yet heard of a KB causing systems to register as non-genuine. Can you give more info on how this happened.
Post4, as yet I've been able to completely prevent any KB updates installing behind my back or any other sneaky downloads. I have done this by rejecting: every update to windows update, every GWX related update, every telemetry related update and every update which wasn't a security fix or a fix for a bug I suffered, since about March 2015. Once things slipped through on one laptop when I upgraded from 8 to 8.1, but I wiped them away by first uninstalling the KB3035583 (and other updates) which got through then annhilating every gwx.exe and other gwx related file I could find on my system. It's worked well so far. I suggest you look back at your update history, make sure no non-security/non-bug-fix updates have been installed since about february 2015. If since about that time you have had no non-security/non-bug-fix updates and have kept windows update on the notify only setting you shouldn't in theory have any problems other than the need to be careful what you tick when you do perform update installations. One way things might slip through is if you are ticking and installing "optional list" updates without first making sure that the "important list" is blank (everything wanted on it already installed, everything unwanted on it hidden).
"And a second laptop, the next day or so, began with the "configuring Windows" at coldpost/boot, did not even proceed to Go and collect $200, simply booted into safe mode, ran the mess given in start thread, and lo &amp; behold -- no more "configuring Windows" at boot or shutdown."
Are you saying that your batch script managed to save a computer which was already trying to install windows 10? Or am I misreading you? Did you just go straight to "advanced startup" and then through to "safe mode with command prompt", run the script, restart and find everything to be ok again? Or were you trying to say something else in this quote?
P.S. Is the below of any use to you, it talks about another unwelcome KB, but this nasty KB is for windows 7 only, not 8/8.1. It might be of relevance to you, if you have it removal my help you.
