The User Profile Service (ProfSvc) is dedicated to storing and managing information about computer users in central location. It allows usage of My Sites, social tagging and newsfeeds, and allows creating and distributing user profiles through multiple sites and farms. When a User Profile service application is created, MS SharePoint server creates and assigns three databases for storing user data – profile, synchronization, and social tagging databases.
The User Profile Service failed the logon error message signals about a corrupted user profile on Windows. This issue prevents you from accessing data stored on the computer.
The error typically occurs after Windows update or creation of new user accounts. The error can appear in Windows 7, 8, 10 and 11 versions, although the message displayed can vary.
You can see examples of what this error reads depending on the OS used.
The User Profile Service failed the logon. User profile cannot be loaded.
The User Profile Service failed the sign in. User profile cannot be loaded.
Other variations of related error messages on blue screen are shown below:
Windows couldn’t connect to the ProfSvc service.
Please consult your system administrator.
The ProfSvc service failed the sign-in.
User profile cannot be loaded.
Known reasons causing the error:
- Wrongly read user profile. This may happen in situations where the antivirus software is scanning the system during the log-in procedure.
- Corrupt user profile. In cases where the user profile is corrupted or has errors/missing essential files, users may run into this error during the logon/sign-in.
- Group Policy settings. If these settings limit or deny creating or loading user profiles, this error can occur. For example, if the settings are configured to delete profiles older than a specific number of days, or if roaming profile changes are prevented from propagating to server, this can trigger User profile service failed the logon/sign-in error.
- Hard disk failure. A failing hard disk and faulty sectors of it can trigger this error.
- Temporary profile login. In cases where Windows logs you in with a temporary profile, this error can appear.
- Faulty Windows update. Sometimes, Windows updates may fail to install completely, or have errors, which can lead to this error.
- Malware infection. Computer malware can mess up essential Windows files and settings, which can lead to this issue as well.
- File system errors. Corrupted or faulty files can trigger this error. Examples include incorrect file permissions, user profile redirections, low disk space and others.
- Registry errors. Missing or incorrect Windows Registry entries can cause issues when logging into user accounts on a computer.
- User profile was moved or deleted manually. Such removal method does not eliminate Security Identifier (SID) from Windows Registry, which causes login errors later. The error may also appear in cases where the user profile was relocated.
- HP SimplePass executable file. This file is known to trigger the error in some cases as it can cause conflicts with the user profile service. This typically happens if the HP SimplePass is faulty, needs to be updated, or incompatible with the operating system used.
Before attempting to try methods listed in this guide, a computer must be restarted first. In many cases, it solves the problem, and the user can successfully log into his account.

Prepare to fix the error: Boot into Safe Mode with Networking and log in as admin
Before we begin, you will need to boot your computer in Safe Mode with Networking. This mode provides a simplified and isolated environment that allows identifying the issues and fixing them more effectively.
Safe Mode on Windows allows booting the system with essential drivers and services only, without the third-party applications and services that might be causing the error during sign-in. The mode gives access to network, in case you need to update software, run AV scans, operating system, or download required files to fix the error.
Boot into Safe Mode with Networking
Method 1. Boot from the Sign-in screen on Windows 11/10/8:
- While on the sign-in screen, press down the Shift key and keep holding it, as you click the Power button in the bottom-right corner of the screen and select Restart. Release the Shift key afterward.
- Once your computer restarts, you will see Advanced Startup Options menu. Click on Troubleshoot, then Advanced options > Startup Settings > Restart.
- Your PC will restart once again and you’ll see a list of options. Use associated key to select Safe Mode with Networking. Normally, the key you need to press is F5.
Method 2. If the sign-in screen won’t load (Windows 11, 10, 8, 7)
- Turn your computer off. Now, press the Power button to turn it back on and start repeatedly pressing the F8 key. This will load Advanced Boot Options menu.
- Select Safe Mode with Networking option using the arrow keys on your keyboard. Press Enter.
Note. Since Windows 8 was released, the F8 key method no longer works by default, so you might need to enable Advanced Startup Options menu via System Configuration menu or simply use the Method 1 to boot into Safe Mode with Networking.
You can also find other methods to boot into Safe Mode with Networking, explained in detail, in this tutorial on our website.
The provided instructions require logging into Administrator’s account. If you only had one user on your computer, then you need to enable hidden Admin account first. Here is how to do it:
- Once you boot your computer in Safe Mode with Networking (using methods described earlier), use Windows search to find Command Prompt, right-click it and select Run as Administrator. Type the given command and press Enter: net user administrator /active:yes.
- You should see a message saying The command completed successfully. Restart your PC now.
