List of all Windows OS Version Numbers

August 14, 2009

Version Check is a basic operation which every developer does while building applications. Wrong Conditions may cause Application Compatibility issues to both developers and users, when they look at migrating the existing applications to a newer OS. The Windows version is actually composed of a bunch of different fields, all packed into an OSVERSIONINFO structure.

The relevant parts of the OSVERSIONINFO are:

Major Version (dwMajorVersion)
Minor Version (dwMinorVersion)
Build # (dwBuildNumber)

List of Windows Client OS with their Version Numbers

Operating System	Version Number
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
Windows Vista	6.0.6000
Windows 7	6.1.7600

Yochay Kiriaty says that “A lot can go wrong when version checking is misused. A user might experience a “silent fail” where the application simply fails to load and nothing happens. Or, a user might see a dialog box indicating something to the effect of “you must be running Microsoft Windows XP or later” when in fact, the computer is running Windows 7. Many other consequences to poor version checking can inconvenience users as well.”

Version details are clearly stated. All should notice here is Windows 7 is not a MS version 7 its 6.1 series. Still I wonder Why MS named Windows7?

Do you have the appropriate version numbers for the Server Operating Systems as well. I would only need Windows 2003 Server and higher; and is their a difference in version numbers when you go between different variations like Enterprise or Standard or Datacenter?

Windows Server 2003 -> 5.2
Windows Server 2003 R2 -> 5.2
Windows Server 2008 -> 6.0
Windows Server 2008 R2 -> 6.1

When you go between different variations like Enterprise or Standard or Datacenter, there is no difference of version. All editions has same version of Windows Server family.
