Windows Startup and Shutdown Sounds (Outdated)

Here&my Windows Startup and Shutdown Sounds video. I have done tons of research to bring you the correct sounds. If there is anything I got wrong, please comment. Things I got wrong: NT 4.0 Beta 1 sounds are the same as Windows 3.1, not Windows NT 4.0. Only builds 1983 - 2000 of Windows 2000 used Windows 2000 RC1 Sounds, builds 2020 and 2031 used RTM sounds. While Windows XP Build 2481 introduced the XP sounds, it still used Windows 2000/ME sounds as default, I used the XP sounds in the video since that build was the first to include them, Build 2485 onwards used XP sounds as default.
