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!

After being plagued by a repeated message from the Windows 10 Mail app about something being wrong with my account, I finally decided to troubleshoot it.
I click on Fix Account, a dialog box that looks like it wants to sign me back into Office 365 pops up. Then another box pops up and simply states “Something went wrong”.
Super useful.

A quick Google search to something so generic leads to the usual laundry list of overly complicated “fixes” that no one confirms actually works.

Lately I’ve been taking the shotgun blast approach because I just don’t have the time to perform 50+ steps to fix what should be a small issue.

Go to the Settings app, click on Apps, scroll down to Mail and Calendar, click Advanced Options, scroll down and click reset, click reset again.
Open Mail, re-add your account, WHAM, working in 5 minutes.
