If you can't logon to an user account in Windows 10 due to "The User Profile Service failed the sign-in. User profile cannot be loaded." error, fix it here.

Multiple user functionality is one of the best bet to use Windows in public domain. To avail this feature, you can create numerous profile in the same Windows copy with having one administrator account in the center. But sometimes, you may be subjected to issues after creating new user account and then using them. Today, we’ll discuss one such issue in which you’re not able to logon an user account/secondary account created on your machine.

The User Profile Service failed the sign-in.

User profile cannot be loaded.

The User Profile Service Failed The Sign-in. User Profile Cannot Be Loaded.

After creating a new user and then log in into that account, you may face the issue login failed. Generally, the root cause here is User Profile Service, that manages the user account activities in Windows.

Except the error message, there is nothing provided to overcome this weird situation. If you’re the admin of your system, and faced this issue after creating a new user account, you can use this procedure to fix this issue:

FIX : The User Profile Service Failed The Sign-in. User Profile Cannot Be Loaded.


Before proceeding, make sure you’re logged in to your administrator account. We’ve illustrated this procedure with C: drive, so remember to replace it with your current system root drive for successive steps.

1. Press Windows Key + R and type C:\Users and click OK. Switch to View tab in the folder so opened, and check Hidden items option in the ribbon. You’ll see a new folder now located inside this folder, named as Default. Rename this folder to Default.old.

The User Profile Service Failed The Sign-in. User Profile Cannot Be Loaded.

2. Now create a new folder named Default under C:\Users. Inside it, create following empty folders such that their location became:










C:\Users\Default\Save Games


The User Profile Service Failed The Sign-in. User Profile Cannot Be Loaded.

3. Next, open administrative Command Prompt and copy NTUSER.DAT file of issued account to C:\Users\Default using following command (replace <USERNAME>):

xcopy C:\Users\<USERNAME>\NTUSER.DAT C:\Users\Default

The User Profile Service Failed The Sign-in. User Profile Cannot Be Loaded.

4. You can now create another user account and reboot, then log-in to that account. You’ll find that you could easily logon there and issue doesn’t occurs now.

Hope this helps! See this fix if Group Policy Client service failed the logon on your user account.

  • Thanks

  • This was not a solution for me. The Users group already had read permissions which I believe is all that is required. The new user’s folder is created without generating an error so access to the Default folder would not seem to be the problem. I see that some people with this problem and it seems prevalent, have fixed it by copying the Default folder from a working copy of Windows 10. Since I have only one machine on Win 10, that is not an option.

    ^^ Article updated for Windows 10 on Oct 6, 2015. :)

  • I can see post after post about this issue and tried various fixes none of which get even close to working anyone got a fix they have used that works.

  • Fixed it by copying the ‘C:\Users\Default’ folder from another PC with windows 10 installed (VIA a flash drive). I renamed the one on my problem machine ‘Default.old’, then I copied the new one in.
    I Note: The ‘Default folder (in C:\Users)’ is hidden, so you have to click on the ‘view’ and check ‘hidden files’.
    I then created a new user. Signed off my ID and signed back on with the new user and — WOW – it worked.
    If you don’t have another Windows 10 PC – just checked the forums, I saw where someone from the UK dropboxed a Default folder for others to use for this fix. They actually had the link to the dropbox in there comments.

  • Kapil Arya

    ^^ Thanks for adding this, will help others for sure :D

  • Didn’t work for me. i am lost at the CMD section

  • Kapil Arya

    ^^ What happens when you run the command? Make sure you’ve substitute your username there.

  • Hi, I couldnt use this method as i am not able to access the admin user at all. And i have only a guest user in my laptop which doesnt allow running command prompt in admin mode(if i try that, after i give my password my laptop just freezes). Please help me out guys.

  • Kapil Arya

    ^^ If you’re on guest account, that’s a different situation. You need to be first opt-out from guest logging and then try the steps.

  • This solution did not work, although I no longer get the error message. Instead, after entering the password for the new account, I get a short loading screen, and it returns me to the login screen that shows both accounts. I can still log into my admin account. Thoughts?

  • Kapil Arya

    ^^ Have you tried step 3 successfully?

  • Ron Davis solution worked for me. Not sure why it does not work for others. Microsoft needs to fix this for all users. This problem has been occurring for months and months.

  • Kapil Arya

    ^^ Nice to see it helped! :)

  • I am stuck on step 3. I am unable to locate file NTUser.dat in any established User folder. I made sure that I updated the view settings to see hidden files and folders and am still unable to locate. I tried to run the xcopy command with several usernames and all have returned “0 File(s) copied”. Where am I going wrong?

  • Kapil Arya

    ^^ Can you try Ron Davis’s suggestion mentioned above and see if it helps.

  • My problem is same like Ben’s…I am unable to locate file NTUSER.DAT in any established User folder…I would to what Ron Davis had said but i do not have a window 10 installed PC :(

    Is it possible to do it with a window 7 PC?

  • Kapil Arya

    ^^ I am not sure about that as I have never tried it. If you like, you may give it a try.

  • what if this issue happened with the administrator account. Is there any other possible way.

  • Kapil Arya

    ^^ You may then reinstall Windows 10 without affecting your data:

  • I can create new user accounts from Windows 10 Settings, see image.

    But a review of regedit shows that no profile has been created for any of these new accounts, only for my original administrator account.

    When I try to sign as as any other user, I get the message saying The User Profile Service Failed the sign-in.

  • Kapil Arya

    ^^ Please try above mentioned procedure and let me know if it helps.

  • This process didn’t work for me. NTUSER.DAT file was not found.

    This is what worked for me:

    As Admin, renamed C:/Users/Default to C:/Users/Default.bak
    From C:Windows.old/Users, copied the Default folder
    Pasted this Default folder in C:/Users

    Did I do something that will cause me a problem?

  • Kapil Arya

    ^^ Nope, if it is working fine :)

  • Seems to be working fine.

    In general, have to say that as a Windows user since 1993, continue to be surprised at the ways Microsoft finds to disappoint me and nudge me toward Apple products. Have a dozen friends who have moved from Windows and all tell me that they would never go back.

  • Looks like a got problem when trying to copy the NTUSER.DAT file from the current user. ” 0 file copied”. From the prompt command, i issued the correct xcopy command Under the Root prompt.
    I am logon using the working Admistrator account that works perfectly so far, and i tried to copy the NTUSER.DAT file of this administration account. Could you please help?
    Thank you

  • Kapil Arya

    ^^ You can try Kumar Shah’s way mentioned above and see if it helps you!

  • Ron Davis’ fix worked for me. I was unable to run apps using “run as different user” or sign in to my computer with a user who had never signed into my computer before. Coworker on Win10 did not have this issue. Copied his Default user profile folder to my machine and functionality was restored on my machine!

  • Kapil Arya

    ^^ Glad you sorted the issue! :)

  • Another way to resolve is to rename the C:\Users\Default folder to Default.old, then copy the Default folder from a known good working host (same OS/version) and paste it into the same folder ie C:\Users\. This worked for me and was a more easy way to test out.

  • Kapil Arya

    ^^ All that matters is you get it sorted :D

  • I tried to copy the folder in the command prompt but it said 0 files copied. I’d love to get this from a working windows 10 PC but I don’t know anybody else who is dumb enough to use this stupid platform. I just want windows 7 back.

  • it works for me,many thanks kapil :)

  • Hi,
    as seen in posts up, the only way to soluce for me was to copy a “Default” Profile on another PC with Win10 (native) on my laptop (migrated 7 -> 10)…
    Win 10 is really a……***************************………

  • Brilliant guys, struggling with this for hours. Copying a c:\Users\Default from a Windows 7 machine did the trick for me!

  • Kapil Arya

    ^^ Awesome 😎

  • Ron Davis’ fix worked for me…. I was going crazy until I found this page of suggestions. I did Kapil’s fix but that did not work. Fortunately I had another laptop running Windows 10 that I could copy the default folder from – onto a flash drive. Thank you all…. you are all geniuses!

  • I would like to try this fix except it appears I am unable to find a non-corrupt NTUSER.DAT file from another computer (I have several, but they were all upgraded so presumably also have corrupt files .. I tried using an upgraded Windows 7 file, but no luck). Question is, is there a reliable source from where I can get this file (e.g., just Microsoft allow a legitimate download of this file)?

  • Kapil Arya

    ^^ NTUSER.DAT is system specific file, you won’t get it from Microsoft. In this case you’ve to use it from the issued user account, as directed in the article.

  • As most windows 10 will be upgrades, rename the C:\users\default folder the go to the c:\windows.old\users folder and copy the default folder from there. That worked for me

  • Kapil Arya

    ^^ Glad the issue is resolved 😎

  • worked for me. I had to reboot the Laptop to enable it to work.

    Renamed Default profile –> Copied Default from C:\Windows.old\Users\ –> Rebooted machine –> Logged on no problem. Reboot before writing off solution. ;)

  • Kapil Arya

    ^^ Post updated with instructions to reboot, thanks for your efforts! :)


  • Kapil Arya

    ^^ Great 😊

    I copied the folder from a Win7 Ultimate PC to fix a Win10 Home laptop… apparently, it doesn’t have to be the same version. Be sure to delete any .DAT files when you copy – they are unique to the user, and don’t appear to be used (that I can tell) in Win10

  • Kapil Arya

    ^^ Appreciate your feedback, thanks! :)

  • This profile problem is a permission issue with the NTUSER.DAT registry file. It appears that there is two set of registry files in the default user file, one is the old registry file and the other is the new registry file created during the upgrade. So when you create a new user on your computer, there is an access denial permission problem when the new user tries to log on to create or copy the default user files. These registry files are hidden. Delete the bad registry files in the default user folder will solve the problem. It works for me.

  • There are at least 9 hidden registry files in the default user folder. Delete the bad files will solve the problem.

  • Kapil Arya

    ^^ Glad it worked 😊

  • it worked :)

  • Kapil Arya

    ^^ 😎

  • Hi. I’m stuck on step 3 as the NTUSER.DAT file won’t copy.

    I don’t have access to another machine so I’m limited on that front.

    I looked at Ron Davis’ solution – the link to the dropbox folder he mentioned doesn’t work as it goes to Facebook. Does anyone else have that link?

    I also tried to find c:\windows.old\users but it doesn’t exist on this laptop so I can’t use that solution.

    Any ideas would be welcome as the upgrade to Windows 10 has caused my external hard drives to stop working and creating a new user profile is the latest solution suggested by Seagate.


  • Kapil Arya

    ^^ Suggest you to try solution mentioned by James in previous comments. See if that helps :)

  • Hi. I can’t use the solution suggested by James because I can’t find a C:\Windows.old\Users\ file on my laptop. Any other options?

  • Kapil Arya

    ^^ Since you tried all possible options and you still have issue, suggest you to go ahead with clean install:

  • Worked for me. Thanks Kapil

  • Kapil Arya

    ^^ Excellent!

  • This worked for me. I got the 0 files copied message but this was caused by NTUSER.DAT being marked as “Hidden”. Once I removed the tick, the file copied OK.

    Why is this simple solution not provide by Microsoft or any of the Blogs?

    At last I can create and use other User Accounts.

  • Kapil Arya

    ^^ Thanks for your inputs!

  • Excellent fix. This was happening on accounts that had been created on a shared machine but not ever logged into. Existing accounts were fine. Recreated the Default user as per instructions and copied an NTUSER.dat from the default profile on another PC (xcopy didn’t work) which then enabled me to log into all the existing accounts. Thanks

  • Kapil Arya

    ^^ I appreciate your feedback, thanks for writing back!

  • my computer set the default admin account to “user 1″… any tips on how to do it when the username has a space in it?

  • Hi, there a miss in copy :-) /H for hidden file
    xcopy.exe C:\Users\Kerphil\NTUSER.DAT C:\Users\Default /H
    Great work

  • Kapil Arya

    ^^ Its up to you to use /H switch as we already enabled Hidden items in step 1 😎

  • I succeed ! creating directories manually and coping NTUSER.dat from another C/Users/ exiting on my computer (Fortunately, my two first children had an account without issues and so I took one of the NTUSER.dat) Many thanks.

  • Kapil Arya

    ^^ Glad it worked for you!

  • This work for me:
    Renamed Default profile –> Copied Default from C:\Windows.old\Users\ –> coud log on broken user and csn create new user ;)

  • Kapil Arya

    ^^ That’s cool!

  • Hello, can you help me? I always get this message when I type in the CMD. “The process cannot accept the file because it is being used by another process.”

  • Kapil Arya

    ^^ Let us know which step gives you this error?

  • In step 3 wich username should we choose??? The admin username or the username from the not working account??

  • Kapil Arya

    ^^ Obviously, the working one, i.e. the admin account.

  • In the cmd section it says 0 files copied

  • Kapil, This worked for me where all the other fixes failed…I did have the user profile freeze on me…I restarted explorer…The the profile was working…At that point I reset CLASSIC MENU SETTINGS which may have caused the freeze…I also had to reload Malwarebytes….New profile now seems to be working…Bad thing is I had tried copying profiles from my other PCs first and that did not work so I am thinking I have corrupt DEFAULT on all my computers as all were Migrated from WIndows 7 (Ten in all)…Thanks for the FIX.
