Win10 upgrade in 'restart' but I don't want the upgrade now

[WPCentral Question]

I fully expected there would be an option to get update sometime in the next year or so. I followed the instructions and now I see the 'future' is only 3 days. If I restart the upgrade will commence, right? I much prefer to wait as I read too many issues have come up. My pc is 8.1 x64. I just want the 'restart to update' gone. Thanks, I appreciate advice. I am NOT tech savvy at all. Dave
