Hi Lynn,
I had posted a new question regarding this issue and here was the response:
"Hi there! I hope you are well. My name is, Zadee. I'm an Independent Advisor and a Microsoft user like you. Sorry to hear about your experience. I'll try my best to help you today.
No, it won't override or change the registry if your device was forced to get upgraded to Win 11. And you can simply go back to the same exact path where you changed it > Remove the value of TargetReleaseversionInfo > OK > Restart the computer. That's it. You should no longer worry about missing any updates for your Win 11.
I could provide a screenshot but that path does not exist in my registry as I have not set this to block any Win 11 upgrades. "
