This article explains how to use C# to determine the name, edition, service pack, version and bits of the host operating system.
For example, the results on my PC would be:
Operation System Information
—————————-
Name = Windows Vista
Edition = Home Premium
Service Pack = Service Pack 1
Version = 6.0.6001.65536
Bits = 64
