How to Fix “The User Profile Service Failed the Sign-In” Error

If you’re facing the “User Profile Service failed the sign-in” error on your Windows device, you’re not alone! This common issue can prevent users from accessing their accounts. Fortunately, there are simple steps you can take to resolve the problem. Let’s dive into some solutions to get you back on track.

1. Restart Your Computer

Sometimes, simply rebooting your device can solve the issue. Try restarting and attempting to sign in again. This is often the quickest fix.

2. Boot into Safe Mode

If restarting didn’t help, the next step is to boot into Safe Mode:

Press F8 during startup to access the Advanced Boot Options menu.
Select Safe Mode and log in with an alternate user account.

In Safe Mode, you can attempt to fix the issue without the usual system processes interfering. This can often lead to quicker results!

3. Edit the Windows Registry

If the issue persists, a corrupted registry may be the cause. To fix this:

Press Windows + R, type regedit, and hit Enter.
Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList.
Locate the profile with .bak at the end, right-click, and rename it by removing .bak.
Restart the system and try signing in again.

This solution can be highly effective, but caution is advised when editing the registry. Small mistakes can cause significant issues, so be sure to follow these steps carefully.

4. Create a New User Profile

If you still can’t sign in, you may need to create a new user profile:

Log in with an admin account or boot into Safe Mode.
Go to Settings > Accounts > Family & other users and add a new user account.
Afterward, transfer your data from the old profile to the new one.

This solution is often the last resort, but it can ensure that the issue is completely resolved.
