List of all Windows OS Version Numbers

V ersion Check is a basic operation which every developer does while building applications. Microsoft says, 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

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.”

Using appropriate conditions to determine the OS is a very important step to ensure App-Compatibility. For more information on Application Compatibility Operating System Versioning and Windows 7 RTM – Read Here and Here.
