Windows NT 9.0

Windows NT 9.0 was released during developments on Windows 9. It was a stunning preview of what Windows 9 would look like, but was criticized due to lack of sufficient security. It was later succeeded by Windows 9, though it was some mystery why a alpha Microsoft Windows OS would succeed it's beta version. Most of it's best features was later removed in Windows 9 in a attempt to upgrade the Windows GUI (graphical user interface) with less strain.

Build 9138

Build 9241
A milestone 2 build of Windows NT 9, compiled on October 2, 2011. Changelog:


 * Fixed the bugs in the start screen, and minimized it making it look a lot more like the Windows 10 menu.
 * Added some Aero transperancy to the taskbar and minimization bar.
 * Changed all instances of "Windows 8.1" in the UI to "Windows 9.0 Beta Release".

Build 9412
This build was leaked as an Insider preview. It was not released because Microsoft did not want people leaking builds of Windows 9 Insider Preview builds.

History
Windows NT 9.0 was in early development when Windows NT 8.4. Windows New Technology 8.5 and Windows 8.5 was skipped in favor of Windows NT 9.0 and 9.0. The headlines read:

=                   MICROSOFT WINDOWS NT 8.5 SKIPPED                      =

Some people were angry that the supposed "NT 8.5" was skipped, but calmed down after Windows NT 9.0 was an half years old. Unfortunately, Microsoft shut down the support switch for the beta and alpha, wanting to replace it with a more classic but malware-weakness free OS. So the idea of Windows 10 came up and killed Windows 9 and NT 9 completely.
