Windows 10’s notifications sound like you’re booting up a Windows 95 PC
Microsoft originally commissioned English musician Brian Eno to create the startup sound for Windows 95. Eno’s piece of music was known widely as the Windows sound. At just over three seconds long, it became an iconic sound as Windows 95 grew in popularity. Microsoft has since changed its sound schemes for many Windows versions over the years, but now it appears to be evoking memories of the summer of 1995 with Windows 10.
The Windows 10 startup sound is still a mystery
