Windows Whistler was the codename for the system that became Windows XP, building on the Windows 2000 and Windows ME era whose welcome animation supplied this melody. Short startup clips like this circulated on forums and video sites as users ripped, remixed and bass boosted familiar system sounds. It sits alongside the classic error sound in meme edits, where recognisable PC noises are made absurdly loud for shock value. The bass boosted take keeps circulating because the tune is instantly identifiable even when heavily distorted.
