5. Restart the computer.

Advanced Troubleshooting Techniques

When simpler methods fail, advanced techniques can be employed to resolve persistent errors. These techniques require a deeper understanding of the system and should be attempted cautiously.

System File Checker (SFC)

SFC scans system files for corruption and repairs any damaged files. To run SFC, follow these steps:

• Open Command Prompt as administrator.
• Type “sfc /scannow” and press Enter.
• SFC will scan and repair any corrupted files.

Deployment Image Servicing and Management (DISM)

DISM is a more comprehensive tool that can repair system images and component stores. To run DISM, follow these steps:

• Open Command Prompt as administrator.
• Type “dism /online /cleanup-image /restorehealth” and press Enter.
• DISM will repair any corrupted system images or component stores.

Manual Registry Editing

In some cases, manually editing the registry may be necessary. This is a delicate procedure and should only be attempted by experienced users.

• Open Registry Editor (regedit).
• Navigate to “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList”.
• Look for a key with a “.bak” extension.
• Rename the key by removing the “.bak” extension.
• Restart the computer.

Creating a New User Profile

If the above methods don’t resolve the issue, you can create a new user profile to bypass the corrupted one. However, using a new profile means you’ll have to transfer your data and settings manually.

Transferring Data and Settings

To transfer your data and settings from the old profile to the new one, follow these steps:

• Open File Explorer and navigate to the following folder:
  

  C:\Users\Old_Username

• Copy all the files and folders from this folder to a safe location, such as an external hard drive.
• Now, open File Explorer again and navigate to the following folder:
  

  C:\Users\New_Username

• Paste the copied files and folders into this folder.
• Once the transfer is complete, restart your computer and log in with the new user profile.

Preventing the Error from Recurring

To prevent the “User Profile Service Failed the Logon” error from reoccurring, it’s crucial to optimize system settings and manage user profiles effectively. By implementing best practices, you can minimize the risk of encountering this issue in the future.

Optimizing System Settings

• Disable Fast Startup:Fast Startup can interfere with user profile loading, leading to errors. Disable it to ensure a complete system shutdown and user profile unloading.
• Update System Drivers:Outdated drivers can cause system instability and profile issues. Regularly update your drivers, especially those related to storage and networking.
• Run System File Checker:Corrupted system files can disrupt user profile loading. Run the System File Checker (SFC) tool to scan and repair any damaged files.

Managing User Profiles

• Create Separate User Profiles:Avoid sharing user profiles among multiple users. Each user should have their own unique profile to prevent profile conflicts.
• Limit Profile Size:Oversized user profiles can cause performance issues and errors. Regularly clean up unnecessary files and folders to keep profile sizes manageable.
• Use Roaming Profiles:For users who access their profiles from multiple devices, consider using roaming profiles. This ensures that their profile settings and data are synchronized across devices.

Troubleshooting Error Codes Associated with the Error

When troubleshooting the “User Profile Service Failed the Logon” error, it’s crucial to identify the specific error code associated with it. These codes provide valuable insights into the underlying cause of the issue and can guide you towards targeted solutions.

Some common error codes associated with this error include:

• Error 0x80070002:This error indicates a general access denied issue. It may occur due to incorrect file permissions or a corrupted user profile.
