On Windows, simply removing an account isn't possible. Now Windows creates a temporary backup account as a safety measure. This happens when the system joins a domain. To resolve this issue, you can use Windows System Restore to revert your system to a previous state, though it may require admin rights based on the Group Policy settings. If that doesn't work, contact your IT department or reimage the machine and rejoin it to the domain. Repairing the account manually is possible but complex and would need verification from the domain server. In short, you'll need to log in using your credentials again if you want full access. Alternatively, consider using a separate laptop drive for system operations, though this won't restore access to school resources.
