支持所有版本
WMI是一个强大的技术：只需要简单的指定一个WMI类名就能返回它类的所有实例：
复制代码 代码如下:
PS> Get-WmiObject -Class Win32_BIOS
SMBIOSBIOSVersion : 76CN27WW
Manufacturer : LENOVO
Name : 76CN27WW
SerialNumber : 1006250300406
Version : LENOVO - 1
你如何知道它有哪些类呢？这里有一款查找工具：
复制代码 代码如下:
function Find-WMIClass
{
param
(
[Parameter(Mandatory=$true)]
$SearchTerm = 'Resolution'
)
Get-WmiObject -Class * -List |
Where-Object { $_.Properties.Count -ge 3 } |
Where-Object { $_.Name -notlike 'Win32_Perf*' } |
Where-Object {
$ListOfNames = $_.Properties | Select-Object -ExpandProperty Name
($ListOfNames -like "*$SearchTerm*") -ne $null
} |
Sort-Object -Property Name
}
设置搜索条件后，代码将搜索出包含指定属性名的类（还可以通过通配符扩大搜索范围）
下面将找出所有包含“resolution”结尾的WMI类：
复制代码 代码如下:
PS> Find-WMIClass -SearchTerm *resolution
NameSpace: ROOTcimv2

接着，就可以使用类名查看它的有效数据啦：
复制代码 代码如下:
PS> Get-WmiObject -Class CIM_CacheMemory | Select-Object -Property *
