powershell windows missing updates

Trying to create powershell script to list missing or pending windows update. The purpose would be to run the script against a list of computers/servers to see if there are any missing updates or hot-fixes and generate a list of what servers you need to look at.

Does anyone have a solutions for this, have been looking around without any success finding scripts to do this.

Powershell script to list missing updates

Script:

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

Sample output:

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

There's a sample script from TechNet that does the core logic you're looking for:

Get-WindowsUpdates.ps1

There's also the older VBScript-based WUA_SearchDownloadInstall.vbs.
