What happened to Windows 9?
They by-passed that name and went straight to Win 10....whatever....thinking about gong to an IMac just to get away from windows....
Sadly Windows 9 followed Windows 8, and since Windows 8 couldn’t find it’s butt with both hands, both got lost.
Microsoft decided to name its upcoming operating system Windows 10 and thus skip Windows 9, despite the buzz that was created in the last few months and pointing to this particular designation for Redmond’s next OS version.
The company, however, never provided a reason for its decision to skip Windows 9 and go directly to Windows 10
Evidence of Windows 8.1 Update 2 was found in some Windows 10 files, so it appears that Microsoft initially designed it to be just a new update for Windows 8.1, but in the end decided to provide it to users under a completely new name and as a stand-alone release.

There’s also the odd fact that the name of each Windows release doesn’t actually match the real version number; for example, Windows 8.1 is actually version 6.3 of Windows. Windows 10 is version 6.4. The last time the release name actually matched the version number was Windows NT 4.0, which was released back in 1996. Windows 2000, which was called NT 5.0 during development, was actually version 5.0. Windows XP was version 5.1. Windows Vista was 6.0, Windows 7 was 6.1, Windows 8 was 6.2, and Windows 8.1 is version 6.3. (WinRT, which powers Metro, is a new and separate beast, but it still sits on top of the core Windows kernel.)

It was only installed on certain IRS hard drives and can no longer be found?
