Winlogon Process Died – Fix in 3 Steps

Quick Answer (for pros)

Boot into Safe Mode. Open an admin command prompt and run sfc /scannow then dism /online /cleanup-image /restorehealth. If that doesn't do it, create a new user account through netplwiz and migrate your data.

What's Going On?

Winlogon.exe is the process that handles your login – the screen where you type your password, the desktop loading, that whole thing. When it crashes, you usually see a black screen or a message like "Winlogon.exe Application Error" or the system just restarts by itself. Common triggers: a corrupted user profile (maybe after a forced shutdown), a broken graphics driver, or a system file that got messed up by a failed update. I've seen this happen on Windows 10 and 11, especially after a power outage or a blue screen.

Fix Step by Step

Step 1: Boot into Safe Mode with Networking

1. Restart your PC. As soon as the Windows logo appears, hold down the power button to force a shutdown. Do this 3 times – on the 3rd restart you'll see a blue screen that says "Choose an option."
2. Click Troubleshoot → Advanced options → Startup Settings → Restart.
3. After the restart, press 5 or F5 to select Safe Mode with Networking.

After you click Restart, your PC will reboot and show a list of numbers. Press 5. You should see "Safe Mode" in all four corners of the screen.

Step 2: Run System File Checker and DISM

1. Press Windows Key + R, type cmd, then press Ctrl + Shift + Enter to run Command Prompt as admin.
2. Type sfc /scannow and press Enter. This checks and fixes corrupt system files. It takes 10-15 minutes. After it finishes, you'll see a message like "Windows Resource Protection found corrupt files and successfully repaired them." If it says it couldn't fix some, that's okay – move to the next step.
3. Type dism /online /cleanup-image /restorehealth and press Enter. This fixes the system image itself. It can take 20 minutes. After it's done, you'll see "The restore operation completed successfully."
4. Restart your PC normally.

Step 3: Test Login

After the restart, try logging in. If the desktop loads normally, you're done. If you still get the Winlogon crash, move to the alternative fixes below.

Alternative Fixes (if the main one fails)

Fix 1: Create a New User Profile

This is the real fix about 70% of the time. A corrupt profile is the #1 cause.

1. Boot into Safe Mode with Networking again (same as Step 1 above).
2. Press Windows Key + R, type netplwiz, and press Enter.
3. Click Add → Sign in without a Microsoft account (not recommended) → Local account.
4. Enter a new username (like "TempUser") and a password (you can leave it blank, but then it won't have a password). Click Next → Finish.
5. Close netplwiz, then restart your PC. Log in with the new account (it will create a fresh profile).
6. If that works, you'll need to copy your files from the old profile. Press Windows Key + R, type %userprofile%, go up one folder to C:\Users, and copy your old folders (Documents, Desktop, etc.) to the new user's folders.

After you create the new user and log in, the Winlogon crash should be gone. Copying files is just to get your data back.

Fix 2: Roll Back or Update Graphics Driver

If the crash happens right after you see the login screen, a bad video driver is the second most common culprit.

1. In Safe Mode, press Windows Key + X → Device Manager.
2. Expand Display adapters. Right-click your GPU (NVIDIA, AMD, or Intel) and select Properties → Driver tab.
3. Click Roll Back Driver if it's available (if you recently updated). If not, click Uninstall device and check Delete the driver software for this device.
4. Restart your PC. Windows will reinstall a basic driver. Then go to the GPU manufacturer's website (like nvidia.com) and download the latest driver manually.

After uninstalling, your screen might be low resolution – that's normal. The driver reinstall will fix it.

Fix 3: System Restore

If you have a restore point from before the crash, this can undo whatever broke things.

1. Boot into Safe Mode or the Advanced Options screen (same as Step 1).
2. Click Troubleshoot → Advanced options → System Restore.
3. Pick a restore point from before the error started. Click Next → Finish.
4. Your PC will restart and restore. This can take 30 minutes.

After System Restore finishes, you'll see a success message. Log in and check if the Winlogon crash is gone.

Prevention Tip

After you fix this, the best thing you can do is create a regular backup of your system image. Use Windows 10/11's built-in Backup and Restore (Control Panel → Backup and Restore (Windows 7) → Create a system image). Store it on an external drive. And avoid force-shutting down your PC – that's what corrupts user profiles in the first place. If Windows freezes, wait 5 minutes before holding the power button.
