powershell - 如何检查挂起的重启？

Question

我试图了解 Windows 机器需要或不需要重新启动的位置。但是，我的脚本抛出错误。

powershell "$key = Get-Item "HKLM:SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired" -ErrorAction SilentlyContinue"

Error :
Get-Item : A positional parameter cannot be found that accepts argument
'Update\RebootRequired'.
At line:1 char:8

我在“命令提示符”中运行此命令。不知道是什么意思!

需要检查2个路径，一个key，需要通过WMI查询配置管理器以检查所有可能的位置。

    if (Get-Item "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired" -EA Ignore) { return $true }
    if (Get-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager" -Name PendingFileRenameOperations -EA Ignore) { return $true }
    try { 
        $util = [wmiclass]"\\.\root\ccm\clientsdk:CCM_ClientUtilities"
        $status = $util.DetermineIfRebootPending()
        if (($status -ne $null) -and $status.RebootPending) {
            return $true
        }
    }
    catch { }

    return $false
}
