It looks a little weird I do agree – but if I do not trap it like this the code returns Windows 2003 Server 64-bit. My XP SP2 64-bit reports the build as 5.2.3790.131072

this doesn't work. it tells u the platform (64/32 bit) of code that runs the context. not the undelying os.

To cope with XP 64-bit I made this change in
#region 2000, XP, 2003
case 5:
switch (minorVersion)

case 2:
if (productType == VER_NT_WORKSTATION)
name = "Windows XP"; // handles XP 64-bit
else
name = "Windows Server 2003″;
break;

@SP1K: For some reason your program is lacking a Main method:

[STAThread]
static void Main()
{
// start your program here
}

+ I opened VS2010.
+ I Created new C# Console Project in .NF 2.0
+ I Copied the code above and pasted it into the Code after deleting the premade VS code.
+ Set it to Release mode.
+ Compiled and got this error:
——————————————————
Error 1 Program 'c:\users\owner\documents\visual studio 2010\Projects\OSCheck-Console\OSCheck-Console\obj\x86\Release\OSCheck-Console.exe' does not contain a static 'Main' method suitable for an entry point OSCheck-Console
——————————————————

What did I do wrong?

Awsome!

Ok, I'm devloping using W7 64-bit, but my app needs to run on both 32 and 64 bit. No problem so far, except I'm using SQLite3. There are two different DLLs depending on the OS version. So, how can I use the detection code to dynamically select which version of the DLL to load?

Ok I have found it!!
To discriminate if you have a Tablet PC running XP

Inside #region EDITION I added

[DLLImport("user32")]
public static extern int GetSystemMetrics(int nIndex);

and

in #region 5 made this change

if ((suitMask & VER_SUITE_PERSONAL) != 0)
{
edition = "Home";
}
else
{
if (GetSystemMetrics(86) == 0) // 86 == SM_TABLETPC
edition = "Professional";
else
edition = "Tablet Edition";
}

I was able to test only on an XP Tablet and an XP Professional laptops.
Thanks for a terrific article and Jonney Tiney fb.

Have you a way of discriminating between XP Professional and XP Tablet?

Hi, thanks for this – Works a treat for Operating System's up to Vista. For it to detect Windows 7, I amended the Windows Vista Detection to look like this:

case 6:
switch (minorVersion)
{
case 0:
name = "Windows Vista";
break;

case 1:
name = "Windows 7″;
break;

case 3:
name = "Windows Server 2008″;
break;
}
break;

Seems to work a treat, but haven't tested on Windows Vista. I now want to know how I would go about fixing the Product part, so it will show 'Professional' etc. (I think Home Premium, Basic and Ultimate should still be working).

Any help is appreciated
