If you are not planning on upgrading any time soon or at all, you can permanently disable the notification by following these couple steps.
I would
NOT follow the steps listed in the OP's link.
Go to add/remove programs, on the left hand side, select "installed updates"
Look for update "KB3035583"
Click on this update and select uninstall. It will prompt for a reboot, once rebooted, go to windows update, and click "check for updates", when the "
recommended" update appears again, right click it, and select "hide"
This will stop the notifications.
On some systems left over remnants may be found in system file "windows\system32\gwx", although i did not find any on mine, and yes, i uninstalled this update, as i have no plans of upgrading.
