How F*ck Windows Update Works

This tool toggles one single official Microsoft registry key:

Key:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\ExcludeWUDriversInQualityUpdate

  • Value = 1 → Excludes GPU drivers from Windows Quality Updates (recommended if you use custom/tuned drivers)
  • Value = 0 → Allows Windows Update to install driver updates normally (default)

Official Microsoft Documentation

Exclude driver updates from quality updates

Why people use this tool

Windows Update frequently replaces your carefully installed or modified GPU drivers with generic Microsoft versions. This often breaks performance tweaks, custom settings, and tools like MPO-GPU-FIX.

This app gives you an easy on/off switch without having to disable Windows Update completely or use Group Policy Editor (which isn't available on Windows Home editions).

Is it safe?

  • Yes — it only modifies one well-documented policy key.
  • Fully reversible (just toggle OFF and reboot).
  • Open source — you can review the code anytime: Form1.cs

Always recommended: Create a System Restore Point before making registry changes.

Quick tip: This tool pairs extremely well with MPO-GPU-FIX for maximum AMD GPU stability.
