查询 Windows 是否处于更新等待重启

如题，今天收到个这样的需求。也是无语。写个脚本做个记录

# 过滤电脑
$computers = Get-ADComputer -Filter {Name -like "cndw*"}

# 执行循环
foreach ($computer in $computers){

# 检测注册表值
 $registryPath = Invoke-Command -ComputerName $computer.Name -ScriptBlock {Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update"}
$rebootRequiredEntry = "RebootRequired"

# 设置记录文件
$logFilePath = "%SystemDrive%\%UserName%\Desktop\waitreboot.txt"
$logfailPath = "%SystemDrive%\%UserName%\Desktop\waitrebootfail.txt"

# 判断条目是否存在
if (Test-Path -Path "$registryPath\$rebootRequiredEntry") 
{
    {
      Write-Output "$computer,The RebootRequired entry exists"
      Out-File -FilePath $logFilePath -Append -NoClobber
    } else {
      Write-Output "$computer,The RebootRequired entry does not exist."
      Out-File -FilePath $logfailPath -Append -NoClobber
            }
}

好了，就这样吧。

后来发现这种执行超级慢，很多电脑不在线。如果你要实地使用，还请做个在线判断。
