DWORD value: DisableOSUpgrade = 1

Github gives a simple batch file to create the key:

upgrade/blob/master/batch/disable-os-upgrade.bat

I suspect the batch file needs to be run in a command window with
administrative rights.

Woody Leonhard revealed that the KB 3083710 and 3083711 updates of 15
October actually change this key back to 0, disabling it and re-
allowing the PUP download of Windows 10! So if you apply those
updates, you'll have to set the value again:

Howtogeek seems to be saying that you must first install

to make that Registry hack effective.

Does anyone know whether that is true?

Woody L. recommends GWX Control Panel, formerly called GWX stopper:

permanently-remove.html

It's been mentioned in these groups before.

The latest version is dated 20 October 2015. This is not an installer
just a program that you download and can then when you need to remove
Windows-10-upgrade malware.

If you use this, please consider donating to the author (with whom I
have no connection). I provide a lot of free information on my Web
site, and many people write about it but very few donate, so I know
how disappointing it can be when few people express their
appreciation for something that takes a lot of work.
