A couple of weeks ago Microsoft changed their windows 10 nagware so that it now schedules the update. If you didn't cancel it you would find yourself upgraded.
They have now removed the way to back out of it apparently.

Looks like unless you take positive action to remove the nagware you will be forced to upgrade.
I can't currently confirm this as my windows laptop is currently being re-installed with Linux and I haven't got round to setting up dual boot.
I just thought I would provide a warning. I previously posted a link to this site which has a little tool to stop the update nags.

If you don't mind using regedit, You can try this.
