The Windows XP startup melody and the Mac startup chime both became instantly recognisable boot sounds for rival personal computers in the early 2000s, which is why swapping one for the other works as a joke. Fan editors later began rebuilding the Windows tune from Mac chime notes, and this deliberately rough version followed an earlier, smoother take that circulated online. It spread through meme edits and YouTube Poop-style videos, where the clash of Microsoft and Apple sounds signals old-school tech humour, and it remains popular as a short, shareable gag and a novelty startup sound for custom setups.
