Is XP the same as NT5?

[Pete]

I have a .Net application that detects the operating system it is running on
(using the My.Computer.Info.OSFullName function). For some users it returns
"Microsoft Windows XP Professional" and for others "Microsoft Windows NT
5.1.2600 Service Pack 2". Are these in fact the same operating system and if
so why do they have different names?

Any help much appreciated,

Pete

Windows2000 = NT5

XP = NT5.1


Prior to Windows 2000 , "NT" operating systems did not use marketing
"gimmicks"

viz, NT4 = NT4

etc

Thank you both your your replies. That at least answers part of my question.
I need to go into this a bit deeper so I'll post a question on a .Net forum.

Yes, they are the same. NT 5.1 is the real built-in name. XP is its
marketing name.
