In addition to the code below that reads the registry and gets exact version information, you can also read from the little-known MS-supplied %windir%\system32\prodspec.ini file. This is on all version of NT and Win2000, and unlike winver, it can tell you exactly what sub-version of an OS you're running. Like Windows 2000 Advanced Server vs. Windows 2000 Professional.

[Product Specification]
Product=Windows 2000 Professional
