powershell windows缺少更新

Question

尝试创建 powershell 脚本以列出丢失或待处理的 Windows 更新。目的是针对计算机/服务器列表运行脚本，以查看是否缺少任何更新或修补程序，并生成您需要查看的服务器列表。

有没有人对此有解决方案，一直在寻找没有任何成功的脚本来执行此操作。

Answer 1

列出缺失更新的 Powershell 脚本

脚本：

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

#List all missing updates
Write-Output "Creating Microsoft.Update.Session COM object" 
$session1 = New-Object -ComObject Microsoft.Update.Session -ErrorAction silentlycontinue

Write-Output "Creating Update searcher" 
$searcher = $session1.CreateUpdateSearcher()

Write-Output "Searching for missing updates..." 
$result = $searcher.Search("IsInstalled=0")

#Updates are waiting to be installed 
$updates = $result.Updates;

Write-Output "Found $($updates.Count) updates!" 

$updates | Format-Table Title, AutoSelectOnWebSites, IsDownloaded, IsHiden, IsInstalled, IsMandatory, IsPresent, AutoSelection, AutoDownload -AutoSize

pause

示例输出：

Creating Microsoft.Update.Session COM object
Creating Update searcher
Searching for missing updates...
Found 4 updates!

有一个来自 TechNet 的示例脚本可以执行您正在寻找的核心逻辑：

Get-WindowsUpdates.ps1

还有老的VBScript-based WUA_SearchDownloadInstall.vbs。
