If you’re running an outdated Windows build or if there are any bugs in the previous build, it can trigger this error. Hence, updating your Windows with the latest available update can fix several issues. Here’s how you can update your Windows 11 PC:
Open Windows Settings by clicking the Start menu and selecting ‘Settings’ or pressing Win+I.
In the Windows Settings, select the ‘Windows Update’ tab on the left pane and click the ‘Check for updates’ button on the right-side pane.
In case there is an update available, Windows will automatically download and install it through Windows Update. Sometimes, you have to manually select the ‘Install’ button to install the available updates.
Once the update is finished, restart your computer.
Replace NTUSER.DAT File in File Explorer
NTUSER.DAT is a profile file that stores details such as settings, preferences, configurations, etc. If this file gets corrupted or damaged, Windows will experience login issues. Hence, replacing the NTUSER.DAT file from another user profile or another computer can fix the problem.
There are many ways you can fix the corrupted NTUSER.DAT file – You can copy the NTUSER.DAT file from the working user profile to the corrupted user profile, copy the NTUSER.DAT file from the Guest account to the Default/corrupted user profile, copy the file from a different computer with the same build and OS to the corrupted computer.
Method 1: Replace the NTUSER.DAT file from the Guest profile or Another Working profile
Whenever you create a new user account, the NTUSER.DAT file is copied to the new profile from the Default Profile folder. If the file Default folder is corrupted all the user accounts will have the same issue.
First, log in to the default administrator account or an account with administrative privileges.
Next, open File Explorer, go to the
C:\Users folder, and check if the Default profile folder is visible.
By default, the Default folder is hidden. To show hidden folders, click the ‘View’ menu from the menu bar, go to ‘Show’, and then click the ‘Hidden items’.
This will make the Default folder visible in the Users folder.
Now, open the Default folder and rename the NTUSER.DAT file into something like e.g. ‘NTUSER.DAT_bak’ or copy the file to an another location on your computer like a local disk or a USB drive (as a backup). But don’t save the file in any user folders.
Copy the ‘NTUSER.DAT’ file from the Guest folder or Administrator folder and paste it into the Default folder.
After that restart your computer and try logging into the user account that’s showing the error.
Method 2: Replace the NTUSER.DAT file from the Another Computer
Another to way fix a damaged NTUSER.DAT file is by replacing the file from another working Windows 11 computer with the same build.
Open File Explorer on the computer with the same operating system and build, then right-click on ‘This PC’ and select ‘Properties’. Now, check if both computers share the same build and OS version.
Next, right-click the Default folder on that computer and copy the entire folder to a USB drive or external storage device.
After that, go back to the computer that’s showing the error and rename the ‘Default’ folder to Default.old.
Then, insert the USB drive and copy-paste the ‘Default’ folder to the Users directory.
After that, restart your computer and make sure that the C:\Users\Default folder has the same permissions as its parent folder C:\Users.
To check the default directory permissions, type the following command in PowerShell:
Ensure that you have the following permission for the Default folder:
NT AUTHORITY\SYSTEM:(OI)(CI)(F) BUILTIN\Administrators:(OI)(CI)(F) BUILTIN\Users:(RX) BUILTIN\Users:(OI)(CI)(IO)(GR,GE) Everyone:(RX) Everyone:(OI)(CI)(IO)(GR,GE)
Method 3: Replace the NTUSER.DAT file of the Default folder from the Corrupted User Profile
First, go to the
C:\Users location and rename the ‘Default’ folder to ‘Default.old’.
Now, restart your computer and boot into safe mode. Then, go to the ‘C:\Users’ folder and create a new folder named Default there. After that, create the following empty folders within the specified location:
Next, open the elevated Command Prompt and use the following command to copy the NTUSER.DAT file of the corrupted profile to C:\Users\Default:
xcopy C:\Users\<USERNAME>\NTUSER.DAT C:\Users\Default
<USERNAME> with the user account name:
xcopy C:\Users\Lavin38\NTUSER.DAT C:\Users\Default
Finally, restart the computer, create another user account, and try logging into the account.
Repair User Profiles using DISM and SFC Scans
Whenever you encounter problems with Windows files, it’s always a good idea to use SFC and DISM commands to fix corrupt files in the Windows system. DISM can fix corrupt files in the component store of the Windows system image and SFC can scan and replace corrupt, missing, and damaged system files.
First, launch the Command prompt as administrator. To do that, search for ‘Command Prompt’ or ‘cmd’ in the Start menu and select the ‘Run as administrator’ option.
To run the SFC scan on your Windows 11, type the following command and press Enter:
To perform a Deployment Image Servicing and Management Tool (DISM) scan, type the following commands in elevated CMD one after the other and press Enter for each command:
DISM.exe /Online /Cleanup-image /scanhealth
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /RestoreHealth
Change User Profile Values using Windows Registry Editor
You can modify the values of the user profile in the Registry Editor to fix the ‘User Profile Services failed the logon’ error. The Windows Registry Editor is one of the advanced troubleshooting methods to fix many issues in Windows 11. But changing the wrong registry value can cause your Windows to malfunction. So, make sure to back up your Windows Registry before you do anything to the registries.
For this, you need to log in to another account with administrative privileges or boot into the safe mode and then edit the registry editor.
To boot Windows 11 in safe mode, open Windows Settings, and select ‘Recovery’ on the ‘System’ section. Or you can just, search for ‘Advanced Startup’ and select ‘Change advanced startup’ settings from the top result.
Then, click ‘Restart now’ to initiate an advanced startup.
After your system restarts, select the ‘Troubleshoot’ option on a blue screen.
Next, go to ‘Advanced options’.
In the next screen, choose ‘Startup Settings’ and then ‘Restart’.
Your system will reboot and you will see a number of startup settings. Select 4 or F4 or press the number/function key corresponding to ‘Enable Safe Mode’ in your system.
Then, sign in to the account that has the problem or any other account that has administrative privileges. You will enter Windows 11 safe mode with minimal options.
Once you are signed in, launch the Windows Run command dialog with Win+R shortcuts and enter regedit.
Windows Registry Editor will automatically start with administrator privileges.
In the Registry Editor, navigate down to the following path in the left panel or copy-paste the following path into the address bar:
When you expand the ‘ProfileList’ folder, you will see a list of entries that starts with ‘S-1-5’. Now, select each registry key with the suffix ‘S-1-5-21’ (SID key) followed by a series of numbers and check the entry named ‘ProfileImagePath’ on the right pane.
Check the ‘Data’ field of ‘ProfileImagePath’ on each folder and locate the user account folder that is causing the error.
In our example, the user profile (rajst) with the SID key – ‘S-1-5-21-2965335139-3050804504-3361004240-1002’ is the one that’s causing the ‘user profile service failed the sign-in’ error.
Once you located the right SID key that’s causing the error, double click the ‘State’ entry and change its value to ‘0’ in the right pane. Then, click ‘OK’.
After that, double-click the ‘RefCount’ entry and set its value data to ‘0’. If you don’t have RefCount, you can create it on your own. To do that, right-click on the SID key and select ‘DWORD (32-bit)’ Value.
Then, specify the ‘RefCount’ value as ‘0’.
In some cases, there are two ‘S-1-5’ folders (keys) with the same SID (same suffix strings) under ProfileList, one folder with ‘.bak’ (extension) at the end, and one without it.
In such cases, rename the .bak folder by removing ‘.bak’ from the end and rename the folder that doesn’t have the extension by adding the ‘.bak’ at the end. In other words, you need to exchange their names. The .bak is actually a backup key that can be used if the original becomes corrupted or damaged.
But, it’s a bit tricky because if you try to remove the .bak extension from the file that doesn’t have it or add the .bak extension to the key that doesn’t have it, you will get this error. It’s because you cannot have two keys with the same name in the same location.
So, first, you have to change the name of the key without ‘.bak’ to something else. For example, rename the other key to something like this:
Next, rename the key that ends with .bak by removing the ‘.bak’ extension from its name.
Then, rename the ‘.new’ folder to .bak.
You have successfully swapped their name. Now, select the key (folder) without the ‘.bak’ extension and change the ‘State’ and ‘RefCount’ values to ‘0’ in the right pane.
If you only have one SID folder with the .bak extension without the original SID folder (SID that ends without the .bak extension, then simply removes the .bak extension and set ‘State’ and ‘RefCount’ values to ‘0’.
Once done, reboot your system and try logging into the account that’s showing the error and see if it fixed the issue.
Boot into Safe Mode and Check Profile Service Status
If you are still encountering the ‘User Profile Service failed the sign-in’ Error, you can boot into Safe Mode and check the status of the User Profile Service. The User Profile Service controls everything related to user profiles including sign-in processes. If this service doesn’t automatically start with the system, you may have problems when signing in to user accounts. Here’s how you can do this:
First, shut down your PC or turn off your PC and then press the power button to turn on the system. And just when Windows starts loading, press and hold the power button to force shutdown your PC.
Repeat this process until you see the ‘Preparing Automatic Repair’ at the bottom of the screen (as shown below).

Your system will restart and show the list of the numbered Startup settings. Now, press 4 or F4 to enter Safe mode.
Once you press that key, Windows will restart and boot into safe mode.
After that, press Windows+R and type ‘services.msc’ then hit Enter.
From the list of services, scroll down and locate the ‘User Profile Service’ and then double-click on it.
In the User Profile Properties window, set the ‘Startup type’ to ‘Automatic’ and ensure that the Service status is ‘Running’. If not, click the ‘Start’ button to start the service. After that, click ‘Apply’ and then ‘OK’.
Now, restart your PC and check if the ‘The User Profile Service Failed the Sign in’ error has been resolved.

Create a New Admin User Account
If you have another administrator account on your device, you can log in to that account and delete the corrupted account or fix the corrupted user profile.
If you are getting the “The User Profile Service service failed the sign-in.” error, when you are trying to log in to your only admin user account, you won’t be able to run some of these troubleshooting procedures to fix the issue. So, creating a new administrator user account can help you resolve this issue. You can boot your system in safe mode to create a new admin user account. Here’s how you can do that:
First, open Command Prompt in Windows Recovery Environment or boot your system into safe mode and then open Command Prompt as administrator.
Open Windows Recovery Environment as shown in the earlier method. When the Choose an option appears, click the ‘Troubleshoot’ option.
Next, click ‘Advanced options’.
Under the Advanced options screen, select the ‘Command Prompt’ option.
Enable Command Prompt on Locked Windows 11 Computer
Now, you cannot use this command prompt to make changes in Windows user accounts. You need to run Command Prompt on Windows 11 lock screen to create a new admin account or enable the built-in Administrator account.
The Command Prompt will start with
X: instead of
C: which is not where Windows is usually installed.
X: is a virtual drive used to run CMD in recovery mode. You need to find out the system drive in recovery mode using the
diskpart command-line tool.
First, type diskpart command (for managing drives) in the command prompt.
Next, enter list volume to get a list of all the volumes or drives connected to your system. From the results, find the volume or drive in which Windows is installed. The Windows drive (which would have a different drive letter instead of C) will have no name or label. Also, you can locate the Windows drive by its size if you already know it. Note down the Windows drive letter from this list.
In the below screenshot, Volum 3 ‘F’ is the Windows drive. Now, note down the Windows drive letter that we are going to use to run the following commands.
After that, type exit to leave diskpart.
Then, enter these commands one by one:
move f:\windows\system32\utilman.exe f:\
copy f:\windows\system32\cmd(.)exe f:\windows\system32\utilman.exe
Note: Remove brackets from
cmd(.)exe in the above-mentioned command. And make sure to replace
f: with the drive letter of the system drive on your PC.
The last command will restart your computer and take you to the log-in screen.
On Windows 11 login screen, click the ‘Accessibility’ icon at the bottom right corner next to the power button, and the Command Prompt will run instead.
Now, in that Command prompt, you can create a new admin account or enable the built-in Administrator account.

After successfully executing the above command, follow it up with this command and hit Enter:
net localgroup administrators <username> /add
<username> with the created username.
net localgroup administrators Lavin38 /add
This command will give administrative privileges to the above-mentioned account.
Now, type net users to check if the account is created on the computer.
Now, let us see how to enable the hidden administrator account.
Enable Built-in Administrator Account
If you don’t want to create another account on your computer, you can enable the built-in administrator account in Windows 11 using the same Command Prompt on the lock screen. Follow the same instructions to run Command Prompt on the lock screen of Windows 11.
