Step-by-Step Guide to Fixing Error Code 43: “Windows Has Stopped This Device”

Error Code 43 might seem intimidating, but with a systematic approach, you can easily fix the problem. Here’s a step-by-step guide prepared by an expert in the field.

Step 1: Remove Unnecessary USB Devices and Restart Your Computer

One of the easiest ways to resolve this error is by rebooting the system while minimizing the number of connected external devices.

  1. Unplug all unnecessary peripherals, especially USB devices.
  2. Power down your computer completely.
  3. Wait 10 minutes to let any residual power in the system discharge.
  4. Restart the computer and plug the affected device back in.

Pro Tip: Use this as a troubleshooting step to isolate if the device itself is faulty—it’s a quick and effective way to reset interactions between your hardware and drivers.

Step 2: Connect the Device to Another Computer

This step ensures the issue isn’t hardware-related. Simply connect your device (USB, printer, external hard drive, etc.) to another working PC.

  • If the device works on the second computer, the issue is likely with your current system settings.
  • If the device does not work, then it might be damaged or corrupted.

Step 3: Reinstall the Problematic Device

A common reason for Error Code 43 is corrupted or incomplete driver installation. You can fix this by resetting the device in Device Manager.

  1. Press Win + X and select “Device Manager.”
  2. Find the device with a yellow exclamation mark under the appropriate category (e.g., Universal Serial Bus controllers or Display adapters).
  3. Right-click the device and select Uninstall Device.
  4. Select “Yes” if prompted.
  5. After uninstalling the driver, click on Action > Scan for Hardware Changes in the top Device Manager menu.

This will force Windows to reinstall the correct driver.

Step 4: Update the Device Driver

Driver updates can fix many compatibility and performance issues associated with hardware. Here’s how to do it:

  1. Open Device Manager.
  2. Locate the problematic device.
  3. Right-click and select Update driver.
  4. Choose Search automatically for updated driver software.

Optional Tool: Use EaseUS DriverHandy to automate driver updates. This tool simplifies the process and reduces the risk of installing incompatible drivers.

  4. Download and install any pending updates.

Quick Tip: Windows updates often include new generic drivers for hardware devices, which can resolve compatibility issues automatically.

Step 6: Update BIOS

Your computer’s BIOS (Basic Input/Output System) plays a fundamental role in hardware communication. An outdated BIOS might cause incompatibilities.

  1. Press Win + R, type msinfo32, and press Enter.
  2. Note your BIOS version under System Summary.
  3. Visit your hardware manufacturer’s website for the newest BIOS update.
  4. Follow exact instructions from the vendor, ensuring power stability and backups during the update process.

Sometimes, toggling the device’s functionality in Windows Device Manager clears temporary system-based conflicts.

  1. Navigate to Device Manager.
  2. Locate the affected device and right-click it.
  3. Choose Disable device.
  4. Wait for 10 seconds, then right-click again and select Enable device.

This simple action forces Windows to reset the connection.
