The Windows Insider program is one designed to let users test out new features before getting to the public, but it's incredibly rare for a person to want access to test out a bug. That happened, however, just last month, as users were hit with the nostalgic tones of the Windows Vista start-up instead of the current one.
In an effort I can only assume is to mess with me specifically, Microsoft has fixed the 'bug' responsible in the Canary channel of the preview build and will now play the standard Windows 11 boot sound instead. The bug change says the "sound was unexpectedly being used instead of the Windows 11 boot sound."
