The Windows startup chime has been a familiar part of Microsoft's operating system for decades, signalling that a computer has finished booting and is ready to use. Online creators later turned that polite sound into a prank by boosting it to extreme volume, sharing loud versions in meme videos, streams and soundboards where the shock value matters more than the melody itself. Because almost everyone recognises the chime instantly, the amplified version still works as a quick joke about technology being louder, stranger and less polite than expected.
