The title shows a recent issue I was having.

While I was enjoying the Windows 11 experience, I didn’t want to reload my PC from scratch just to upgrade when it’s released so close to now.
I decided to do a roll back, which went well. No issues when it was back except one that reared its head after a few day.

My PC did not want to stay on Windows 10, it kept moving me back to Windows 11.

I turned off the Insider feature, but that didn’t seem to matter.

I read a few other people having this problem and they provided a slew of fixes, most of which required registry/policy changes, or changing telemetry data gathering (more on that in another post).
Ultimately it seemed the most sure-fire way was to do a factory reset to Windows 10.

Since this is being pushed via Windows Update, I tried something interesting.

It was prepared to restart the PC to do the install, but before I let it do that, I did the standard fix for most Windows Update issues.

I stopped the WindowsUpdate service, renamed the SoftwareDistribution folder in C:\Windows, and started the service.

Several reboots and a manual update check later, no more attempts to upgrade!
