Sounds exclusive to Windows 10 build 10074 till 10122. These sounds are very similar to the ones used in Windows 10 RTM onwards. The sounds used in the RTM onwards were debuted in build 10125. User Account Control sound is close to Windows Background in the RTM onwards. I don't own the image used in this video. Also sorry for the screenshot in Simplified Chinese.
