Category:Windows Prototypes OSes

This category contains all the prototypes of Windows OSes that have hidden midis on them.

Interesting things to note about Prototype OSes & their Midis
Windows Chicago (Windows 95 Beta) - It has Canyon.mid & Passport.mid, but it's unknown if they are the rare alternative versions found on Windows 3.0, or the ones in Windows 95-Windows 2000. However, there's no Clouds.mid yet, which is a special midi file only found in a Windows 95, meaning it was included in the final version only.

Microsoft Memphis Build 1423 (A Windows 98 Beta) - Strangely it doesn't have any midis, yet Windows 98 (the final version) has Passport and Canyon like the previous Windows 95 does.

Proof: https://www.youtube.com/watch?v=tA5HaCZ8WeU&t=530 (pause the video at 8:55, and you'll see that there's no .mid files. Media Player can play .mid files, and it IS set to "All Files", but there's no midis to be seen.)

Microsoft Windows Millennium Edition Build 2419 (Windows ME Beta 2) - All the midi files have been removed, which explains why all the midis from the 90s have gone and haven't been put back. Also, Onestop, Town and Flourish haven't been put here yet.

Proof: https://www.youtube.com/watch?v=Bk2wkFSOR64&t=700 (pause at 11:42. and even though blurred, you can see that all the midi files have been removed in this build of Windows ME; the media player is set to "All Files", but there's no midis or RMI midis anywhere.)
