PowerShell 技能连载 - 管理 Lenovo BIOS 设置（第 1 部分）

不幸的是，没有一个标准的方法来管理计算机厂商的 BIOS 设置。每个厂商使用专有的方法。对于 Lenovo 电脑，您可以使用 WMI 来存取和转储 BIOS 设置：

Get-WmiObject -Class Lenovo_BiosSetting -Namespace root\wmi |
Where-Object CurrentSetting |
ForEach-Object {
    $parts = $_.CurrentSetting.Split(',')
    [PSCustomObject]@{
        Setting = $parts[0]
        Status = $parts[1]
        Active = $_.Active
    }
}

结果看起来类似这样：

Setting                             Status                                Active
