powershell windows 缺少更新

Question

嘗試創建 powershell 腳本以列出丟失或掛起的 Windows 更新。 目的是針對計算機/服務器列表運行腳本，以查看是否有任何丟失的更新或修補程序，並生成您需要查看的服務器列表。

有沒有人對此有解決方案，一直環顧四周，但沒有成功找到執行此操作的腳本。

Answer 1

TechNet 中有一個示例腳本，它執行您正在尋找的核心邏輯：

獲取-WindowsUpdates.ps1

還有較舊的基於 VBScript 的 WUA_SearchDownloadInstall.vbs 。

Answer 2

用於列出缺少的更新的 Powershell 腳本

腳本：

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

示例輸出：

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