PowerShell 技能连载 - 识别操作系统详细信息

当您查询操作系统详细信息时，WMI 会返回一个数字：

PS> Get-CimInstance -ClassName Win32_OperatingSystem |
      Select-Object -ExpandProperty SuiteMask
272

SuiteMask 实际上是一个位掩码，其中每个位代表一个特定的细节。要将其转换为可读的文本，请使用标志枚举：

$SuiteMask = @{
  Name = 'SuiteMaskText'
  Expression = {
    [Flags()] Enum EnumSuiteMask
    {
      SmallBusinessServer             = 1
      Server2008Enterprise            = 2
      BackOfficeComponents            = 4
      CommunicationsServer            = 8
      TerminalServices                = 16
      SmallBusinessServerRestricted   = 32
      WindowsEmbedded                 = 64
      DatacenterEdition               = 128
      TerminalServicesSingleSession   = 256
      HomeEdition                     = 512
      WebServerEdition                = 1024
      StorageServerEdition            = 8192
      ComputeClusterEdition           = 16384
    }

    [EnumSuiteMask][int]$_.SuiteMask
  }
}

Get-CimInstance -ClassName Win32_OperatingSystem | Select-Object -Property Caption, SuiteMask, $SuiteMask

这将添加一个计算得出的 SuiteMaskText 属性，该属性列出了已安装的操作系统扩展：

Caption                  SuiteMask                                   SuiteMaskText
-------                  ---------                                   -------------
