While many of these sounds were eventually refined or replaced in later builds (notably build 10125 and the final RTM release), they set the groundwork for the modern Windows 10 acoustic identity.
Attempted to bridge the gap between Windows 7's elegance and Windows 8's speed. As Microsoft experimented with blur effects and transparency in the UI, the audio design team crafted a matching soundscape.
