To diagnose the issue, you can check the Event Viewer for detailed error logs. Look for entries related to Autopilot.dll or WIL errors. These logs can provide insights into the root cause, such as file corruption, missing dependencies, or software conflicts.
Step 1: Repair or Replace the Autopilot.dll File
If the Autopilot.dll file is corrupted or missing, you can attempt to repair or replace it. Follow these steps:
- Download a fresh copy of Autopilot.dll: Obtain the file from a trusted source or use the System File Checker (SFC) tool to restore it.

- Register the DLL: Open Command Prompt as an administrator and run the command
regsvr32 Autopilot.dllto register the file.
If the issue persists, proceed to the next step.
Step 2: Check System Integrity
System file corruption can lead to DLL errors. Use the following tools to check and repair system integrity:
- Run the System File Checker (SFC): Open Command Prompt as an administrator and execute the command
sfc /scannow. This tool scans and repairs corrupted system files. - Use the Deployment Imaging Service and Management Tool (DISM): Run the command
DISM /Online /Cleanup-Image /RestoreHealthto fix Windows image issues.
These tools can resolve underlying system issues that may be causing the Autopilot.dll WIL error.
Step 3: Reinstall Affected Software
If the error occurs when using specific software, the application may have corrupted dependencies or conflicts. Reinstalling the software can resolve these issues:
- Uninstall the software: Go to Control Panel > Programs > Uninstall a Program, and remove the affected application.
- Download the latest version: Obtain the most recent version of the software from the official website.
- Reinstall the software: Follow the installation instructions and ensure all dependencies are correctly installed.
This step ensures that any corrupted or missing files related to the software are replaced.
Step 4: Update Windows and Drivers
Outdated Windows versions or drivers can cause compatibility issues with system files. Ensure your system is up to date:
- Update Windows: Go to Settings > Update & Security > Windows Update, and check for updates.
- Update drivers: Visit the device manufacturer’s website to download and install the latest drivers.
Keeping your system updated can prevent DLL errors and improve overall stability.
Step 5: Perform a Clean Boot
Third-party applications or services may interfere with system files. Performing a clean boot can help identify the cause:
- Open System Configuration: Press
Win + R, typemsconfig, and press Enter. - Disable startup items: Go to the Services tab, check Hide all Microsoft services, and click Disable all.
- Restart your computer: This will boot Windows with minimal services and applications.
If the error does not occur during the clean boot, a third-party application is likely the cause.
