📝 Notes
Ventoy is a portable tool — it requires no installation and writes only a small HKCU preference key.
Ventoy does not create an uninstall entry; delete the extracted folder to remove it.
Ventoy writes a special partition structure to the target USB drive (not to Windows registry).
Requires administrator elevation to write to physical disks.
The ShowAllDrives = 1 setting is a safety risk — it exposes internal fixed disks as flash targets. Leave at 0 unless you know what you're doing.
