10 Ways to Fix “User Profile Service Failed the Sign-in” in Windows 11

Are you encountering the error message “The user profile service failed the sign-in. User profile cannot be loaded” or “User Profile Cannot be Loaded” or “User Profile Service Failed the Logon” when trying to sign in to your Windows 11 operating system? This error typically appears immediately after entering your username and password on the Windows logon screen.

This issue is primarily caused by a corrupted user profile or when the user profile fails to start. Given that this error prevents you from accessing your system, resolving it can be more complex than other Windows errors. However, it is possible to fix it. In this article, we will present several troubleshooting methods to resolve the “The User profile cannot be loaded” error on Windows 11.

You can employ these troubleshooting methods by using another account with administrative privileges. If you are locked out of your sole user account, you can enable the hidden administrator account and troubleshoot your PC through that. This post will also demonstrate how to activate the hidden administrator account on Windows 11.

What causes the “User Profile Service Failed the Sign-in” Error in Windows 11

Encountering the ‘User profile service failed the sign-in’ error when attempting to access your system can be a frustrating experience. This issue can be caused by several factors, some of which we will delve into below.

One possible cause of this error is an improper Windows Update. When updates are not installed correctly, it can interfere with the user profile service, leading to login failures.

Another potential cause is the incorrect configuration of default profile permissions or NTFS permissions. Such incorrect settings can prevent the user profile service from running correctly, resulting in login failures.

A third factor that can trigger this error is incorrect values or a corrupt Windows registry. The registry plays a critical role in the proper functioning of the user profile service, and any corruption or incorrect values can lead to login issues.

A fourth possible cause is corrupted user profile files. This can occur due to a variety of reasons, such as hardware failures or malware infections, and can prevent successful login attempts.

Additionally, resizing a partition on the hard drive can also cause the ‘User profile service failed the sign-in’ error. This is because such an action can disrupt the user profile service, rendering it unable to function correctly.

Moreover, it is possible for an antivirus program to block access to the profile folder during authorization, resulting in login failures.

Lastly, improper shutdowns and restarts can lead to user profile service errors. When a system is not shut down or restarted correctly, it can cause issues with the user profile service, preventing successful logins.

3. Replace the NTUSER.DAT file

NTUSER.DAT is a crucial file that contains various details, such as settings, configurations, and preferences. If this file gets corrupted or damaged, Windows might encounter login problems. Fortunately, there are multiple ways to fix the corrupted NTUSER.DAT file.

Method 1: Replace the file from Guest profile or another working profile

One of the ways is to replace the NTUSER.DAT file with a new one. You can copy the file from a working user profile or another computer with the same build and operating system. This method can be done in three different ways.

1. First, log in to the default administrator account or an account with administrative privileges.

2. Then, open File Explorer and navigate to the C:\Users folder to check if the Default profile folder is visible.

3. If it’s hidden, enable the Show hidden items option from the View > Show > Hidden items.

4. Next, rename the NTUSER.DAT file to ‘NTUSER.DAT_bak‘ or copy it to another location as a backup.

5. Afterward, copy the ‘NTUSER.DAT‘ file from the Guest or Administrator folder and paste it into the Default folder.

Finally, restart your computer and try logging into the user account that’s experiencing issues.

Method 2: Replace the file from another PC

1. Firstly, open File Explorer on a computer with the same operating system and build, and check if both computers share the same build and OS version.

2. Then, right-click the Default folder on that computer and copy the entire folder to a USB drive or external storage device.

3. Afterward, go back to the computer that’s showing the error and rename the ‘Default‘ folder to Default.old.

4. Insert the USB drive and copy-paste the ‘Default‘ folder to the Users directory.

Finally, restart your computer and ensure that the C:\Users\Default folder has the necessary permissions.

To check the permissions, type the following command in PowerShell:

icacls c:\Users\Default

Ensure that it shows the following permission for the folder:


Method 3: Replace the file of the Default folder from corrupted User profile

1. Firstly, go to the C:\Users location and rename the ‘Default‘ folder to ‘Default.old‘.

2. Next, restart your computer and boot into safe mode.

3. Then, create a new folder named Default in the ‘C:\Users‘ folder and create the following empty folders in the specified locations:

C:\Users\Default\Save Games

4. Afterward, open the elevated Command Prompt and copy the NTUSER.DAT file of the corrupted profile to C:\Users\Default by using the following command:

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

Make sure to replace <USERNAME> with your windows account name.

Finally, restart the computer, create another user account, and try logging into the account.

4. Repair the System Files

In the event of encountering issues with Windows files, it is prudent to resort to SFC and DISM commands to rectify corrupt files within the Windows system. These commands serve distinct purposes in addressing specific file corruption problems.

DISM operates by resolving corrupt files within the component store of the Windows system image. On the other hand, SFC scans and replaces any corrupt, missing, or damaged system files that may be present within the Windows system.

To run the SFC scan on your Windows 11 operating system,

1. Launch the Command Prompt as an administrator. This can be achieved by searching for ‘Command Prompt’ or ‘cmd’ in the Start menu, then selecting the ‘Run as administrator’ option.

run cmd as administrator
run cmd as administrator

Subsequently, type the following command and press Enter to initiate the SFC scan:

sfc /scannow
sfc scannow
sfc scannow

In order to perform a Deployment Image Servicing and Management Tool (DISM) scan, the following commands should be executed sequentially in elevated CMD mode. Enter each command, then press Enter:

DISM.exe /Online /Cleanup-image /scanhealth
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /RestoreHealth
DISM Scan to repair the Component Store
DISM Scan to repair the Component Store

These commands are essential in maintaining the integrity of the Windows system, and it is advisable to use them periodically to keep the system in optimal condition.

5. Change User Profile Values in Windows Registry

In order to resolve the ‘User Profile Services failed the logon’ error on Windows 11, it is possible to modify the values of the user profile in the Registry Editor. This is one of the advanced troubleshooting methods available for fixing many issues in Windows 11.

However, modifying the wrong registry value can cause Windows to malfunction, so it is important to back up the Windows Registry before making any changes by going to File > Export.

export registry
export registry

1. To begin, log in to another account with administrative privileges or boot into safe mode and then edit the registry editor.

2. Start by booting the Windows PC into Safe Mode using the Windows Safe Mode Guide, then sign in to the account that has the problem or any other account that has administrative privileges.

3. Once signed in, launch the Windows Run command dialog with the Win+R shortcuts and enter ‘regedit‘. The Windows Registry Editor will automatically start with administrator privileges after hitting the Enter key.

023 regedit in the run dialog box

4. Next, navigate down to the following path in the left panel of the Registry Editor or copy-paste the following path into the address bar:

Computer\HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\ProfileList

5. When you expand the ‘ProfileList‘ folder, you will see a list of entries that starts with ‘S-1-5‘. 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‘ column of ‘ProfileImagePath‘ on each folder and locate the user account folder that is causing the error.

For example, the user profile (Bhanu) with the SID key – ‘S-1-5-21-4209958417-3236085656-3328254797-1001‘ may be the one causing the ‘user profile service failed the sign-in’ error.

6. Once you have located the right SID key that is causing the error, double-click the ‘State‘ entry and change its value to ‘0‘ in the right pane.

Similarly, double-click the ‘RefCount‘ entry and set its value data to ‘0‘.

If you don’t have RefCount, you can create it yourself by right-clicking on the SID key and selecting ‘DWORD (32-bit) Value’. Then, specify the ‘RefCount‘ value as ‘0‘.

In some cases, there may be 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, you need to rename the .bak folder by removing ‘.bak’ from the end and rename the folder that doesn’t have the extension by adding ‘.bak’ at the end. This is because the .bak is actually a backup key that can be used if the original becomes corrupted or damaged.

However, renaming the keys can be a bit tricky because you cannot have two keys with the same name in the same location. Therefore, you must first change the name of the key without ‘.bak’ to something else, such as ‘S-1-5-21-2965335139-3050804504-3361004240-1002.new’.

Then, rename the key that ends with ‘.bak’ by removing the ‘.bak’ extension from its name. Finally, rename the ‘.new’ folder to ‘.bak’. Once this is done, select the key (folder) without the ‘.bak’ extension and change the ‘State’ and ‘RefCount’ values to ‘0’ in the right pane.

6. Check User Profile Services

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:

1. Once you have booted into Safe Mode, press Windows+R and type ‘services.msc’ then hit Enter.

services.nsc run command
services.nsc run command

2. From the list of services, scroll down and locate the ‘User Profile Service’ and then double-click on it.

3. 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.

7. Recreate the User Account

In case you are encountering issues with your user profile on Windows 11, you might consider deleting the problematic profile and creating a new one. However, it’s important to note that deleting a user account will lead to the deletion of all its data, including files on the desktop, downloads, photos, music, apps, and other files. If you have already backed up your library files on Cloud services such as OneDrive or saved the files in a different location, or there are no important files in the library folders, then you can safely delete the user profile and create a new one.

005 put a username and password

Next, enter the username in the ‘Who’s going to use this PC?’ field. If you want to create an account without a password, leave the ‘make it secure’ fields empty and click ‘Next.’

If you prefer to add a password to the account, enter and re-enter the password under the ‘Make it secure’ field. Then, select three security questions and answer them below. Finally, click ‘Next’ to create the user account.

After following these steps, you can restart your computer and sign in with the new user account. It’s important to note that when creating a new account, it’s recommended to use a strong password and enable two-factor authentication to enhance security.

8. Use the Startup Repair
