Code 39 is an error in Windows indicating that a device driver is missing or corrupt. To fix it for free, you can start by uninstalling the problematic device from Device Manager and then restarting your computer, which may automatically reinstall the driver. If that doesn't work, you can run the built-in Windows troubleshooter for hardware and devices or check for system updates to ensure you have the latest drivers. Finally, consider using the Command Prompt to run “sfc /scannow” to repair any corrupted system files.
