Windows XP launched in 2001 with a built-in tour that walked new users through its fresh interface, and Bill Brown's intro music set the tone for that first look. As the system became one of the most widely used versions of Windows, its sounds became part of everyday computing memory for a generation of users. Years later, clips of the tour intro began circulating in nostalgia videos, memes and retro tech edits, where its calm, early-2000s sound instantly signals a simpler era of personal computing.
