What is the version previous to newest version?

Answer 1

We're talking Microsoft Windows, right?

In backwards order, starting with the newest (current) version:

Windows 7

Windows Vista

Windows XP

Windows ME

Windows 98 Second Edition

Windows 98

Windows 95

Windows 3.1

Windows 3.0

Windows 2.11

Windows 2.10

Windows 2.03

Windows 1.01

Of course, there are types for almost all of these versions. Like Windows 7 has Home, Business, Ultimate, etc. Vista had Home, Professional, Ultimate, etc.

These are just desktop versions of Windows too. There were also "workstation" versions of Windows prior to Windows XP. For example: Windows 3.11 was the workstation version of Windows 3.1 and then NT, NT 3.1 and NT 3.51 came out. Windows NT 4.0 Workstation coincided with Windows 95. Windows 2000 Professional coincided with the Windows 98.

And all of this doesn't take into consideration "server" versions of Windows like Windows NT Server, Windows 2000 Server, Windows Server 2003 and Server 2008, etc.
