When logging into your account on Windows, the Operating System uses the user profile files in the C drive to load your Windows account. If these user profile files are corrupted, the OS cannot log in to your account. So, when the OS cannot access the desired user profile, we get the error message “The User Profile Service service failed the sign-in.”
