Fix ‘User Profile Service service failed to sign-in. User profile cannot be loaded.’ Issue in Windows 8/Windows 8.1

If you are facing this issue while trying to log on to Windows 8/Windows 8.1 computer, it means that somehow the default user profile got corrupted, which is preventing you from signing in. In order to rectify the issue, the easiest way is to remove the existing, apparently corrupted, user profile. You are not required to create a new user profile as it is automatically created when you first log on to the computer.

Since this process requires administrative rights on the computer, you must enable the built-in Administrator account by going to the safe mode before you finally remove the corrupted user profile of the user.

You can enable the built-in Administrator account by following the steps given below:

    ■Log on to Windows8/Windows 8.1 using manually created administrator account.
    ■On the start screen type CMD.
    ■From the search results right-click Command Prompt.
    ■From the context menu, click Run as administrator.

Once you have successfully enabled the built-in Administrator account, you can then follow the steps given below in order to remove the user profile of the culprit user:

    ■Log in using built-in Administrator account.
    ■Press Windows + R keys on your keyboard to open the Run dialog box.

    ■Once done, close the Registry Editor window.


Once the entire user profile is deleted from the Registry Editor window, you can now try logging in to the same user account. The issue should be resolved by now.
