[1.20.3] - 2026-06-08

Fixed

  • Drive enumeration no longer crashes on missing WMI properties. FixedDriveService read MediaType/BusType with Convert.ToUInt32(value ?? 0u), but WMI returns DBNull.Value (not null) for absent properties, so Convert.ToUInt32(DBNull.Value) threw and aborted the whole scan on some hardware. Reads now go through a ToUInt32Safe helper that treats null and DBNull as 0.
  • Uninstaller trusted-directory check no longer accepts sibling folders. IsUnderTrustedDirectory used a bare StartsWith, so C:\Program Files Evil\… passed the C:\Program Files check. It now compares on a normalized directory boundary (trailing separator) so only true sub-paths of a trusted directory are accepted.
