How to Properly DDU Your GPU Drivers Before Reinstalling

If you're experiencing stutter, black screens, driver crashes, or frame dips after updating GPU drivers, it's time to do a clean sweep. DDU (Display Driver Uninstaller) removes every last trace of your old NVIDIA or AMD drivers, ensuring a truly clean install for your graphics card.

What Is DDU?

DDU (Display Driver Uninstaller) is a powerful tool used to completely remove graphics drivers and registry entries. It’s essential when switching GPU brands, resolving corrupt driver installations, or troubleshooting persistent graphical issues.

Unlike Windows' built-in uninstaller, DDU scrubs everything: driver remnants, leftover folders, registry keys, and even GPU telemetry services.

When Should You Use DDU?

• Switching GPU brands (e.g., NVIDIA → AMD)
• After failed driver updates
• Black screen or no signal after rebooting
• Frequent driver crashes in games or benchmarks
• Upgrading to new GPUs and want a fresh slate

Before You Start

• ✅ Download the latest DDU from wagnardsoft.com
• ✅ Download the latest GPU drivers (from NVIDIA, AMD, or Intel)
• ✅ Boot into Safe Mode for maximum cleanup efficiency

How to Use DDU (Step-by-Step)

Follow these steps to perform a clean driver uninstall:

Step 1: Boot Into Safe Mode

• Press Windows + R, type msconfig, and hit Enter
• Go to the Boot tab → Check Safe Boot → Restart

Step 2: Run DDU

• Extract the DDU ZIP and run Display Driver Uninstaller.exe
• Select your GPU vendor (NVIDIA, AMD, Intel)
• Click Clean and Restart

Step 3: Install Fresh Drivers

• Once Windows boots normally, install your latest driver package
• Restart your system again to apply changes

Advanced Tips

• Disable automatic driver installation via Group Policy or Windows settings
• Use msconfig again to uncheck Safe Boot after DDU completes
• Always run DDU offline (disconnect Ethernet/Wi-Fi)

Final Thoughts

DDU is a must-have utility for any PC gamer or enthusiast dealing with unstable or bloated GPU drivers. Doing a clean install ensures that you avoid conflicts, registry junk, and potential performance loss.

Run DDU before major driver updates or GPU swaps for a smooth experience and better system stability.
