Encountering the “User Profile Service failed the sign-in” error can be a frustrating experience, especially when you’re trying to regain access to an old or previously used PC.

Scenario Overview

The user in question had an older PC that was no longer functioning optimally. Attempting to restore or reset the system led to the emergence of the “User Profile Service failed the sign-in” message. The PC’s age and security concerns—such as possible malware infections—further complicated recovery efforts. Additionally, the user struggled to access essential recovery tools like Command Prompt or System Restore, primarily because of forgotten passwords linked to outdated credentials.
