Windows 10: I removed my school account, but I still have some restrictions.

This is my personal pc, but I added a school account and windows 11 education edition to this a while back, but now I removed my school account, but still have the restrictions. Is there a way to remove them?

:)

 

School Account added restrictions to PC. Removed school account, but restrictions remain... How do I remove them?

I previously used a school account on my personal PC which added restrictions to my PC. I've since removed the account, but after restarting the restrictions remained (things like backup settings, device manager, policy settings).

Is there an extra step I require to do?

 

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Remove Deactivated Work Or School Email Account

I have an organizational email account that has been deactivated, current guides online say the following:

"If you need to remove an account from your PC:

1. Select Start > Settings > Accounts > Access work or school .
   
2. Select the account you wish to remove, then select Disconnect
   
   ...."
   

However, the only option presented at this section is "Manage" which forwards me to my organization's page to login. The account has since been deactivated with no way to get to the next step.
I have been getting notifications from my system that "There is a problem with a work or school account click her to fix now" but obviously can't login to remove the account from the system.
Is there a work around to remove the account without logging in?
