How to check windows machine are x64-bit and x86 (32-bit ) architecture

Logic to detect system architecture for windows machine are 32-bit or x64-bit from power-shell. This is very small function but admin and script-er use a lot in day to day task .I am sharing one function which will deduct bitness of windows machine.We can check OS architecture from remote machine also.

{

    $sArchOS = (Get-WmiObject Win32_OperatingSystem).OSArchitecture

    If($sArchOS -eq '64-bit' )

    {

        $Script:sArchOS = "x64"

        Write-Host $sArchOS

    }

    Elseif($sArchOS -eq '32-bit')

    {

        $Script:sArchOS = "x86"

        Write-Host $sArchOS

    }
