📝 Notes
GPU-Z is fully portable — most users run it directly without an installer.
When run as portable, the HKCU\SOFTWARE\techpowerup\GPU-Z key is still created on first launch to store window state.
A setup installer variant exists but is not commonly used; it adds an uninstall entry to HKLM.
GPU-Z does not register file associations or system services.
Sensor logging writes to a .txt or .csv file in the same directory as the executable.
