I'm at wit's end with this. I have two Windows 7 computers in my home that are continually downloading and trying to install Windows 10. We DID NOT reserve it on either computer. It's slow DSL here so it's a huge problem. Here's what I did to try to stop it. Uninstalled the following updates, reboot after each, then hid them in WU: KB3035583 KB2952664 KB3021917. Removed the temporary install files using Disk Cleanup. They are stored in $Windows.~BT. It takes two runs with a reboot in between to remove the whole folder. 3.5 GB on one computer, almost 6 GB on the other. Reset WU with the downloaded WindowsUpdateDiagnostic. Reboot. Ran SFC/scannow. Reboot. Reinstalled WU with FixIt 50202. That blasted my WU history. Reboot. Still, after each reboot, Windows will within a half-hour or so triggers the download of all 3 to 6 GB of install files using Automatic Update. it does not show as an available update in the WU interface, recommended or optional. It's doing it on its own with no apparent way to stop it. I gave up, turned off automatic updates and called Microsoft for help. I have spent 6 hours on the phone and remotely. Level 2 support ran this command: ***net user administrator*** /active:yes*** without stars - which turns out to do nothing other than enable the built in administrator account, as I suspected when it was run. That was the sole extent of the help. They were obviously just blowing me off. I called back and was told it will be Sunday before another Level 2 tech can call me. In short, MS is no help with this. So, to sum up, no GWX prompt, no indication in WU that windows 10 is even available as an option to install, yet when Automatic Updates is on it downloads the entire installer and tries to install it silently at each reboot, over and over again. Anyone know how to stop this? Anyone? Please? Edited for spelling and clarity.
