This article provides five straightforward fixes to address the “User Profile Service failed the sign-in” error in Windows 11, helping you troubleshoot and resolve the problem efficiently.

How Do I Fix The User Profile Service Failed Sign-In Error?

1. Restart Your Computer

Sometimes, a temporary glitch can cause the “User Profile Service failed the sign-in” error. A simple restart can often resolve these temporary issues.

1. Click the Windows icon in the taskbar.
2. Click the Power icon.
3. Select Restart.
4. After your computer restarts, attempt to sign in to your account.

2. Sign in with a Temporary Profile and Copy Data

If you can sign in with a temporary profile, you can copy your data from the corrupted profile to a new one.

1. Sign in to the temporary profile. You will usually see a notification saying you are logged in with a temporary profile.
2. Press Windows Key + R to open the Run dialog box.
3. Type %SystemDrive%\users and press Enter.
4. Locate your original user profile folder (it will likely have your username).
5. Copy the files and folders you want to keep (e.g., Documents, Pictures, Downloads) to a temporary location or an external drive.
6. Create a new user account (see next step).
7. Log in to the new user account and copy the data from the temporary location or external drive to your new user profile folder.

3. Create a New User Account

Creating a new user account can bypass the corrupted profile.

1. Press Windows Key + I to open the Settings app.
2. Click Accounts.
3. Click Family & other users.
4. Under “Other users,” click Add someone else to this PC.
5. Follow the on-screen instructions to create a new user account. You may need to provide an email address or create a Microsoft account.
6. After creating the new account, sign out of your current account and sign in to the new account.
7. If the new account works, you can transfer your data from the old account to the new one.

4. Fix the Corrupted Profile in Registry Editor

This method involves editing the registry to point to the correct user profile path. Caution: Incorrectly editing the registry can cause serious problems. Back up your registry before proceeding.

1. Sign in to an administrator account.
2. Press Windows Key + R to open the Run dialog box.
3. Type regedit and press Enter to open the Registry Editor.
4. Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList.
5. Look for a key that starts with S-1-5 followed by a long number. There might be two keys, one ending with .bak and the other without.

• If you see a key ending with .bak, rename the key without the .bak extension (e.g., rename S-1-5... to S-1-5...old). Then, rename the key ending with .bak to remove the .bak extension (e.g., rename S-1-5....bak to S-1-5...).
• If you see two keys with the same long number, but one ends in .bak, delete the one without the .bak extension, and then rename the .bak one to remove the .bak extension.
• If you only see one key, proceed to the next step.

1. Click on the key you have identified (the one without the .bak extension).
2. In the right pane, double-click on ProfileImagePath.
3. Ensure the value data is the correct path to your user profile folder (e.g., C:\Users\YourUsername). If it’s incorrect, correct it.
4. Close the Registry Editor and restart your computer.

5. Run System File Checker (SFC)

System File Checker can repair corrupted system files that might be causing the issue.

1. Type cmd in the Windows search bar.
2. Right-click on Command Prompt and select Run as administrator.
3. Type sfc /scannow and press Enter.
4. Wait for the scan to complete. This may take some time.
5. If SFC finds and repairs any files, restart your computer.
