User Account Control is the Windows security feature that asks for permission before a program can change system settings, and its prompt sound became familiar to anyone using Windows in the 2010s. This clip preserves the version heard in build 10074, an early Windows 10 preview build, before the final release refined the system sounds. Short system tones like this are often saved and shared on soundboards because they are instantly recognisable, even out of context, and they now work as a nostalgic cue for old computers, permission screens and early Windows 10 setups.
