Windows 10: I can’t seem to disconnect my organisation from my personal computer

I’ve recently connected my pc to my schools system through microsoft office and now it seems they’re latched to it with all microsoft application uninstalled, in settings my account removed i’m still getting pop ups in some setting saying i can’t access all of them or i have to have a 6 digit long pin because my organisation says so? how can i remove this?

uTorrent disconnecting my internet connection

AT&T wasn't much of a help. All they suggested was to replace my router and modem with their products.

The disconnections never happen when I surf the web

 

"Some settings are managed by your organisation" on a personal computer

I am seeing the "Some settings are managed by your organisation" message in my Windows Update Settings, and this is impacting my ability to install updates. This problem appeared in the fall of 2017.

I'm running Windows 10 Pro, version 1709, OS Build 16299.664 on a personal device (Surface 2 Pro). It has never been part of an organisation (I am the sole owner, bought it new), although I was until recently a member of the Insider Programme.

So far, I've run the system file check (SFC) scan as recommended

here, and received the message "Windows Resource Protection did not find any integrity violations.". A Safe Mode reboot did not resolve the issue either. I also looked into
regedit to see if I had an AllowTelemetry value (as recommended

here)... but I don't.

Any help/suggestions is greatly appreciated!

 

Removing some of these settings are being managed by your organisation

How do I remove the "some of these settings are being managed by your organisation" statement in Windows 10 21H2. i have not set one up and this is a personal computer.
I've tried steps 2 and 5 from this article and it doesn't work.
I can't use Group Policy Editor as I don't have the Professional edition of Windows 10.
