A list of Windows Operating System Version Number
What I mean by version number is not necessary mean the OS name or service packs. For example, Windows 7, doesn’t necessary mean it’s the 7th version of Windows coming from Microsoft. As we have discussed before on our opinion of Why Windows 7 is named Seven. Here is a list of versions of Windows, since Windows Operating System 1.0. The distinguish of versions rather than OS names are important for developers and the distinguish of Windows structure. The list can also be found on MSDN OSVERSIONINFO Structure
Here is the list of Windows OS by Version Numbers
| Operating System | Version Number | Other Information |
| Windows 1.0 | 1.04 | |
| Windows 2.0 | 2.11 | |
| Windows 3.0 | 3 | |
| Windows NT 3.1 | 3.10.528 | |
| Windows for Workgroups 3.11 | 3.11 | |
| Windows NT Workstation 3.5 | 3.5.807 | |
| Windows NT Workstation 3.51 | 3.51.1057 | |
| Windows 95 | 4.0.950 | |
| Windows NT Workstation 4.0 | 4.0.1381 | |
| Windows 98 | 4.1.1998 | |
| Windows 98 Second Edition | 4.1.2222 | |
| Windows Me | 4.90.3000 | |
| Windows 2000 Professional | 5.0.2195 | |
| Windows XP | 5.1.2600 | Current SP3 |
| Windows XP Professional x64 Edition | 5.2.3790 | |
| Windows Vista | 6.0.6000 | Current Version changed to 6.0.6002 with SP2 |
| Windows 7 | 6.1.7600 | RTM |
Note this list does not including Windows Servers which also can be included as list by versions.
UPDATE: Infact you can check the version of OS you are running by typing "ver" in the Command Port (Start>cmd)
From the list we can conclude and have a better view of different OS and their similarities is exhibited by their version number. And that’s why some people are calming that Windows 7 is just another Vista.
