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 anOSVERSIONINFO structure.
The relevant parts of the OSVERSIONINFO are:
- Major Version (dwMajorVersion)
- Minor Version (dwMinorVersion)
- Build # (dwBuildNumber)

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.”Reference- Windows Team Blog
