Operating system

Problem
When we trying to boot the windows showing the error “The user profile service failed the login. User profile cannot be loaded.”
Solution
This issue may occur if the user profile folder was deleted manually. A profile folder that is manually deleted does not remove the Security Identifier (SID) from the profile list in the registry. For solving the above problem we used the third party utility called Reprofier.

Login with default login user account. Open the Reprofiler utility. Select the corrupted user profile and select assign as shown in figure.
And restart the machine
