Windows 10 is downloading using fully one third of my allotted data for this month. Thank you pin heads at Microsoft. I read several articles trying to find a patch to prevent the download. I enabled the Administrator account and from there modified (added) two entries to the registry using regedit. I also used gpedit script to modify the group policy (Win 7 Pro). The registry entries and the group policy editor do the same thing, that is prevent new OS updates from installing. I also downloaded and ran Never 10 from Steve Gibson Research. When run it confirmed that my system was configured to never update to a new OS. Never dd find a patch to prevent the download. Oh well, at least it should not install 10.
