It was said in these forums a while back, that update KB3035583 was the one to remove and then hide, so that the Win 10 update nagger disappeared from the task bar.
This I did - uninstalled it, then, was careful to note that when it came up again, to hide it.
This was fine up until recently.
I have my Win 7 laptop set on "check on updates but let me choose when to download and install'. This has in fact NOT been happening now, for a couple of months. NO notification about new updates has presented, even though, checking manually reveals many. Anyway, that's another issue.
Yesteday, I manually checked for updates. There were 11 important ones. Being in a bit of a hurry, and being of the view that I had previously delt successfully with the KB3035583 issue, I selected all 11 in one hit, and told it to download and installl.
To my horror, upon restart, THERE was the update nag on my taskbar. I checked what important updates had just been installed, and THERE was KB3035583 - even though I had previously hidden it.
I uninstalled it again. Restarted my computer .. checked updates again .. IT WAS DOWNLOADING ITSELF AGAIN, WITHOUT MY KNOWLEDGE OR CONSENT.
I stopped it. Went to check for updates. There it was, under important updates I right clicked on it, and chose 'hide'. I worked on my computer for a while.
A couple of hours later, I turned it back on to do some more work. Decided to 'check for updates'.
THERE, AGAIN, was KB3035583, under important updates. I right clicked and selected 'hide'. I had to do this TWICE again, to make it hidden. That was last night.
As I type this, I'm checking again on my lappie. it hasn't appeared again so far.
And you wonder why I call Win 10 an abomination ?
Look at the angst it created for me, the time that it wasted for me. I could have spent my time and mental energy in happier, more productive things than having to contend with this rubbish, and then, spending another 20 minutes typing this - as I feel duty bound to do.
W 10 = ABOMINATION !!!
I'm so glad I saw all this coming and have taken up Linux !!!
