    How to Fix "The User Profile Service service failed the sign-in. User Profile cannot be loaded." Error in Windows 10


    A user profile is a collection of settings that make the computer look and work the way you want it to for a user account. It is stored in the user's C:\Users\<user name> profile folder, and contains the account's settings for desktop backgrounds, screen savers, pointer preferences, sound settings, and other features. User profiles ensure that your personal preferences are used whenever you sign in to Windows.

    A user's profile folder also contains their personal folders such as the 3D Objects, Contacts, Desktop, Documents, Downloads, Favorites, Links, Music, OneDrive, Pictures, Saved Games, Searches, and Videos folders.

    OPTION TWO

    Create New Profile for Account with "The User Profile Service service failed the sign-in. User Profile cannot be loaded."


    This option is to be used when Option One did not help to fix the corrupted profile to allow you to sign in to the account again.

    This option will replace the profile of the account with a new default profile to use instead. This will not delete the user account.


    1 Sign in to an administrator account not affected by this corrupted profile issue.

    None of the registry profiles have a RefCount DWORD, what does this mean? Did Microsoft do away with this? Running 64 bit Pro 1909.

    Hello @ppappas,

    I can't find the reference material from Microsoft for the RefCount DWORD, but it's used in the process to fix the profile. If the DWORD is not there for the affected account, you would just need to add it as outlined in the steps.

    OK, thanks. Unfortunately, that did not help my situation. Do you think the fact that on this system the major user doc folders (Documents, Downloads, Music, Pictures & Videos) being on a 2nd disk drive can cause profile issues? This was done when the system was running Windows 7 and the first SSD I installed was rather small. I used the Windows trick to point all this user data to a secondary HDD.

    There's always a potential of breaking these folders when moving their locations if a mistake was made, but it shouldn't affect the user profile folder unless you moved it as well.

    Hi Shawn, had a moment's panic this morning when this happened to me for the first time ever.

    Fortunately I schedule a system restore point to be created daily, and fortunately it completed successfully. Problem solved. Worth adding using System restore with caveats- naturally depends if user enabled SR and has a restore point and if it completes successfully.

    Regback was disabled by MS- might be worth referring to enabling that as a further protective measure and if enabled, make use of it
    Enable Automatic Backup of System Registry when Restart in Windows 10
    or any other recent registry backup the user might have. E.g. Tweaking.com offers scheduled registry backup.

    This appears to offer another approach (first option 3 - backup and copy C:\Users\Default)

    I'm not sure about that "C:\Users\Default" method either since it's only the default profile used to create a new profile with. For example, when creating a new account in Windows 10.

    It doesn't replace the profile of existing accounts though unless you delete the profile using something like Option 2 here to have a new profile created for the account.

    Uh . . . okay, this describes the problem I'm having right now with a rebuilt system . . . but, so far as I can see, the solution doesn't work for me because there is only one log-in account shown and it won't load. I can't get into windows 10 pro at all, it just loops around the error message and redisplaying my account login page. What did I miss in the explanation above?
