将上面的列表放入hashtable中，以便将整数值Map到描述：

$editions = @{

  1  = 'Ultimate Edition'
  2  = 'Home Basic Edition'
  ...
  41 = 'Enterprise Edition without Hyper-V, Server Core'
  42 = 'Hyper-V Server'
}

$sku = (Get-WmiObject Win32_OperatingSystem).OperatingSystemSKU

'Edition is {0}.' -f $editions[$sku]

但是请注意，OperatingSystemSKU在Server 2003和更早版本上不可用。在这些系统上，您必须检查Caption和/或OSProductSuite属性。

您也可以使用“联机获取Windows版本”。

我通常在Windows10上运行这样的程序，你也可以从ubr上看到你的每月更新。

# vercheck.ps1
$reg = Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion'
$releaseid = $reg.releaseid
$ubr = $reg.ubr
$displayversion = $reg.displayversion

[pscustomobject]@{
  releaseid = $releaseid
  displayversion = $displayversion
  ubr = $ubr
}

releaseid displayversion  ubr
