Introduction of AutoPlay.
Drives of type DRIVE_REMOVABLE do not use the autorun.inf file. Any discovered removable media are handled by AutoPlay. All other handling is as before.
XP Service Pack 2 and up (includes Vista)
Drives of type DRIVE_REMOVABLE now use autorun.inf but continue to be handled by AutoPlay. Any specified AutoRun task needs to be paired with the mandatory action key to appear as an option within the AutoPlay dialog. Otherwise the AutoRun task is omitted.
All other handling is as before.
