Do you get the message “The user profile service cannot log in. When starting Windows 11/10.” Unable to load user profile “? This message is displayed when you enter a password on the Windows session startup screen and the default user profile does not start. Instead, it takes over a corrupt user profile by changing the lock screen and desktop background. Since the correct profile was not loaded, unable to boot. If you encounter this frustrating problem, one of the solutions below will properly fix it away.

Reasons for the error “The user profile service could not log in”

There are many reasons why you may encounter the “Unable to log into user profile” error. Variations of this error are “Unable to load user profile” and “Unable to log into user profile service”. If you receive any of these error messages, the default Windows user profile has been corrupted, which can be attributed to one or more of the following factors:

• Invalid Windows update:User Account Control (UAC) is designed to prevent unauthorized changes to your Windows device. Any irregular or incomplete update or crash can sometimes damage the host files which are required for the proper functioning of UAC.
• Error resizing a partition: When resizing a partition from “Disk Management”, sometimes these parts can get corrupted and generate an invalid user profile.
• Antivirus– If the antivirus program scanned the system while trying to log in, it might cancel the correct user profile and run the wrong one.
• Abnormal shutdown and restarton guest login– If you did not come out smoothly with the local account created on your computer, you may encounter a user profile error when logging in later.

Solutions for User Profile Service Failed Windows 11/10 logon failure

The good news is that none of the above causes are a serious problem. You can easily repair a corrupted user profile by using one of the troubleshooting solutions below.

You should try the first few simple methods first. Only look for more complicated and time-consuming solutions at the end if the easy ones don’t fix the problem.

1. Restart or shut down Windows 11/10 from the lock screen

Sometimes a simple restart or shutdown from the lock screen window is all it takes to fix the problem.

Whether you are in administrator or guest logon mode, useWygrać+Lto exit and go to the Windows lock screen. Go to the administrator profile (if you previously used a guest profile to log in) and click lock screen shutdown / restart options. Remember to log in as an administrator the next time you run it.

2. Delete the local user account in Windows 10/11

If the user profile error is due to an improper shutdown and restart during guest login, you can temporarily remove an unnecessary local account using the Run commandnetplwiz.

1. After logging into the computer with the wrong user profile, run the Windows Run command option withWygrać+rand enternetplwiz.

2. The Advanced User Account Control Panel screen appears. Enter the administrator password to continue.

Sometimes an error occurs because the system refuses to accept the administrator password. In this case, use Windows Safe Boot to perform these steps. (Check out this solution in the FAQ below.)

3. Click “Delete” next to your Guest / Local account. Even if you are currently logged into your computer with your local account, the local profile here will be deleted.

4. UseWygrać+Lto exit the local account login window. Restart your computer and make sure to sign in again with your regular Microsoft account.

3. Move the NTUSER.Dat file to the default username folder

The user profile consists of custom menu items for the desktop, downloads, documents, music, movies, saved links and they are stored in a folder under “C: / Users”.

For each of these profiles, Windows creates a .dat file named NTUSER.dat. Contains custom user settings.

1. Go to the required local account in “C: / Users” and “Cut” the NTUSER.dat file for that account.

2. “Paste” the .dat file into the “Default” username folder.
3. Delete the local account folder and restart the computer to verify that the correct user profile is loaded.

4. Repair the Windows user profile using the command prompt

Always Green Command Prompt can fix some hard disk related problems that may have caused the user profile error problem. For both Windows 11 and Windows 10, run it in administrator mode from the Start menu search.

1. First, run the Deployment Image Servicing and Management Tool (DISM) scan, which helps to repair the Windows image and can resolve the user profile services error.

DISM.exe / Online / Cleanp-image / scanhealth

2. Likewise, the System File Checker (SFC) command is the best way to repair corrupted Windows files, including user profile settings. This is a very simple command that can fix many computer problems at once.

5. Use Windows Registry Editor in Safe Mode

Windows Registry Editor (Regedit) is one of the best solutions to fix the “User Profile Service Could Not Log In” error. To do this, troubleshooting is done in safe mode.

1. In Windows 11, go to “Advanced Start” from the Search menu (or search in the Start menu). In Windows 10, the appropriate option is “Change advanced startup options”.
2. Click “Restart Now” to initiate an advanced restart.

3. After rebooting, a blue screen will appear. Select “Troubleshoot”.
4. Go to “Advanced Options -> Startup Settings” and restart the device again.
5. Upon reboot, you’ll see a series of startup settings that can be accessed with the number keys (1-9) or the function keys (F1-F9). Select “Enable Safe Mode”.
6. After logging in, you will enter Windows 11/10 in Safe Mode. In this mode, the minimum options are visible.
7. S run the Run Windows command option with + and enter . This task will be created automatically with administrator privileges.Wygraćrregedit

8. Navigate to the following path in the registry editor:

ComputerHKEY_LOCAL_MACHINESoftwareMicrosoftWindowsNTCurrentVersionProfileList

9. Check recent entries in “ProfileList” for duplicates, for example the entries have similar names, but at least one will contain a .bak file.
10. Rename the .bak extension, if present in the last entry, to simply .ba. For a second duplicate entry, rename it, but add the extension “.bak”. Remove any remaining .bak extensions, if present, in case of duplicate entries.
11. Remove the “.ba” extension from the renamed entry.

12. Right-click and edit the “status” of the profile entry with the .bak file removed. Basically we’re changing the active default user profile with a little registry tweak.

13. Change the hexadecimal DWORD value from a numeric value to “0”. Click “OK” to save the settings.

14. Restart the computer in Normal mode.

The error “Login User Profile Service Failed” should disappear when you log back in.

6. Reset your Windows 11/10 computer to resolve the “Unable to log in user profile” error

If all of the above options fail, you can use the Reset option to revert to a clean factory reset of the Windows 11/10 operating system. You must be connected to the internet to perform a cloud reset.

The Windows 11 reset method is discussed in detail in this tutorial. But the basic steps that are common to Windows 10 are summarized below:

1. Go to “System -> Recovery -> Reset this PC” and click “Reset PC”.
2. Select “Keep Files” or “Delete All”. Select the first option to not save a backup.
3. Select “Download from the cloud” to reinstall Windows 11/10. Downloading will take some time.
4. When you see the “Ready to reset your computer” screen, click “Next” to continue.
5. Sit back and wait for the reboot to finish as it will take some time to download. The entire procedure can take anywhere from a few hours to a full day, so we recommend the reset method only if other methods fail to resolve the issue.
