Solution 1

Or try this:

PS C:\Users\jeffh> $os=Get-WMIObject win32_operatingsystem
PS C:\Users\jeffh> $os.OSArchitecture
64-bit

Found at: http://msgoodies.blogspot.com/2008/05/is-this-powershell-session-32-bit-or-64.html

Solution 2

So be it:

[System.Environment]::Is64BitOperatingSystem

Solution 3

echo %PROCESSOR_ARCHITECTURE%

Solution 4

"echo %PROCESSOR_ARCHITECTURE%" down-voted? Must not be powershelly enough, which is funny if you look at the other examples using WMI and other aliases.

oh well, try this:

($env:PROCESSOR_ARCHITECTURE -eq "AMD64")

EDIT - pointed out in the comment that this is not the version of windows, it's the arch. FWIW- It's not the "real" arch, it's what WOW64 is reporting to the app. But you are right... if it's x32 powershell, it'll say x86. Often times this will get you what you want but...

Either way, http://support.microsoft.com/kb/556009 is the registry location to the correct value, and here's a script.

Get-ChildItem HKLM:\HARDWARE\DESCRIPTION\System\CentralProcessor\ | Get-ItemProperty -Name Identifier | Select-Object -Property PSChildName,Identifier | ft -AutoSize

Solution 5

With PowerShell:

(gwmi win32_computersystem).SystemType

Using the Powershell console, what command/commands can be executed to determine if the 32 or 64 bit bersion of Windows Server 2008 is installed?

  Very similar to this question: serverfault.com/questions/27495/…

  I see now you asked both :) The environment variable option given in your other question should be trivial to get from PowerShell.

  Yes... I wanted a PowerShell solution as well and I decided it was better to break my 2 part question into 2 questions since everyone were only answering the first part.

That's not nearly reliable enough, I've seen software that installs to "C:\Program Files (x86)" on 32-bit Windows.

Ehh, true. Someone had already beat me to the best answer, so I figured I'd give the lazy one.

Perhaps because it's the processor architecture, and not the version of Windows?

I believe the question was about the version of Windows, not the processor architecture.

One-liner: (gwmi win32_operatingsystem).osarchitecture

Technically, that's .NET reflection...not native powershell. I'll show myself out...

That's the type of processor, not Windows bitness. More Info:

I think having this here downvoted is informative—thanks!
