Difference between Windows Server X64 and I64


What is the command to find out if my Windows 2008 Server version is X86, X64 or IA64?

I know winver command, but it is gives the Windows version and SP Level. It does not tell me, if my windows is X64 or IA64.

Does anyone know the command to find out the difference? (Please note that in, we have different support packages for SAP Netweaver components, that are installed on X64 and IA64).

Also what is the difference between x64 and IA64?

I will answer this although this is more for Google,

In Windows desktop right click on My PC or My Computer, then properties and you will get OS version and it express if X86 or IA64.

You could also use the command SYSTEMINFO in a command prompt window

Now differences between them:

X86 This is Intel based 32 Bits Processors

X64 This is Intel Based 64 Bits Processors

IA64 This is Itanium 64 bits Processors
