📝 Notes

• BleachBit's own settings are stored in %APPDATA%\BleachBit\bleachbit.ini — not in the registry.
• The portable version writes no registry keys.
• BleachBit removes registry entries from other applications as part of its cleaning function — running it will modify HKCU and HKLM keys belonging to other software.
• The "wipe free space" feature requires administrator elevation.

# Run BleachBit silently with a preset (useful in MDM scripts)
& "C:\Program Files (x86)\BleachBit\bleachbit_console.exe" --clean system.tmp system.recycle_bin
