uninstall KB3035583
I did just that the other day. It’s gone.
The nagware popping up 20x a day was too much.
KB3035583 will just reinstall unless you specifically "hide" the update in Windows Update. Even if you do that, it might not be good enough. A friend's Win7 computer on which I hid KB3035583 managed to upgrade itself to 10, which she emphatically did not want. She may have clicked the wrong button on a Microsoft prompt by mistake, but she tried NOT to upgrade, and was upgraded anyway.
So, I have given up on uninstalling and hiding updates to stop Windows 10.
If you don't want 10, either install Steve Gibson's "Never 10"...

...or install Josh Mayfield's GWX Control Panel

Steve Gibson is a very well known, well respected old pro. I have been using his programs for decades without a single problem.
Here's an article about the two programs:
5583 will come back in a later download, so go to the waiting queue, check for it and the others below, and r/c it: “hide”, and it won’t try again.
Others to uninstall and “hide”:
