β οΈ Warning: DDU makes deep system changes. Only use it if you're comfortable with advanced troubleshooting, or if standard driver removal tools fail.
Prerequisites
Before using DDU, make sure to:
- Back up important data. 
- Create a system restore point. 
- Download the latest version of DDU from the official website. 
- Download the latest GPU drivers from your hardware vendor: 
Step-by-Step Instructions
1. Boot into Safe Mode (Recommended)
Running DDU in Safe Mode ensures maximum effectiveness and reduces conflicts.
How to Enter Safe Mode:
- Press - Windows + R, type- msconfig, and press Enter.
- Go to the Boot tab. 
- Under Boot options, check Safe boot > Minimal. 
- Click Apply > OK, then Restart. 
π‘ Tip: After using DDU, return here and uncheck "Safe boot" to start Windows normally.
2. Run DDU
- Extract the downloaded DDU - .zipfile.
- Open the extracted folder and run - Display Driver Uninstaller.exe.
- If prompted by Windows SmartScreen, click More Info > Run anyway. 
3. Configure DDU Settings (Optional but Recommended)
Before uninstalling, go to Options and consider enabling:
- Prevent downloads of drivers from Windows Update. 
- Remove PhysX (for NVIDIA users). 
- Remove AMD Audio Bus or HD Audio (if needed). 
Close the options dialog when finished.
4. Uninstall Your GPU Driver
In the main DDU window:
- Choose your GPU type from the dropdown: NVIDIA, AMD, or Intel. 
- Click one of the following: - β Clean and restart (recommended) 
- π Clean and do NOT restart (for installing multiple drivers consecutively) 
- π Clean and shutdown (if you're replacing a GPU) 
 
π Most users should choose Clean and restart.
DDU will now remove the selected drivers and restart your system.
After Using DDU
- Boot into Normal Mode (if you used Safe Mode). 
- Install the latest GPU driver you previously downloaded. 
- Reboot again to ensure changes take effect. 
Troubleshooting Tips
- If DDU doesn't launch, try running it as Administrator. 
- If your system behaves abnormally after DDU, use your System Restore point. 
- Still having driver issues? Consider checking for Windows corruption using: - sfc /scannow 
π Final Notes
- Only use DDU when necessary. It's not needed for every driver update. 
- Never interrupt DDU during the uninstall process. 
- Do not use your system for other tasks while DDU is running.
