I'm using Windows10 Pro. I find a recent surprise guest on my desktop, the Win10.Upgrade.Assistant icon. My VPN is indicating I've got my download bandwidth being used profusely, what-da-heck! I have consistently tried to stop this latest Win10 Creator's Fall Update 1709 from installing permanently. It stopped my LAN card from its ability to
WOW/WOL.
I already had placed a new IntelPro1000 LAN to replace 2 on-board
Realtek Lans that were rendered useless for WOW/WOL when I upgraded to Win10 initially.
It really upset me that the latest Fall 1709 Update took out my Intel Lan's ability to WOW/WOL since that is the reason I had to go out and buy one initially. I haven't found a solution to date as no new drivers for my IntelPro1000 LAN have helped, and tried rolling back driver with the much touted KB3073930 wushowhide.diagcab, don't get me started on that. Soooooo.........tried all the usual suspects:
First try: Did the rollback update method over and over -

No luck, Windows 10 Upgrade Assistant would reload and update the next day stopping my WOW/WOL ability until I rolled it back.
Second try: Did the turn off Windows Update method using Settings-Advanced Options -

No luck again, Windows 10 Upgrade Assistant installed again the next day and started the download again.
Third try: Did the Admin Command Line method - https://www.windows-commandline.com/start-stop-windows-update-service/
3 times the charm? Not really, Windows 10 Upgrade Assistant back up like a bad penny.
FINAL Solution: Stumbled on this recent Oct.14.2017 YouTube video, https://youtu.be/egD8DcEYI3E. Its a bit slow watching so basically is:
Go to Task Scheduler - TaskSchedulerLibrary - Microsoft - Windows - Update Orchestrator.
Then pick UpdateAssistant - right click - Properties - Triggers Tab - Edit each Trigger then click Enabled box to Disable - OK.
Repeat for UpdateAssistantCalendarRun.
It finally worked!
No updates downloading in the background, no Upgrade Assistant installed. This solution seems to be holding until Microsoft finds a way around it on the next upgrade push. Lastly, don't forget to go to Control Panel - Programs & Features and uninstall the Win10 Upgrade Assistant and the Upgrade if its been downloaded.
