GPO for controlling Automatic Update Policies - Ignored

mhopper29ok, I don't think there's anything I need to take out of this and yes, the original source for this was a TechTarget email years and years ago. Just a warning: this will download and install any (and all) updates without any warning or prompting - I guess you could CTRL-C it but it doesn't prompt for anything. After this, worth looking in the WindowsUpdateClient & Setup logs in event viewer.

#Based on a script from a TechTarget email;
#This is going to automatically download and install updates, not provide options.

#Defines update criteria: we're interested in "software" (i.e. Windows/ Office, not drivers or anything) that are not yet installed
$newUpdateCriteria = "IsInstalled=0 and Type='Software'"

#Search for new updates.
$newUpdateSearcher = New-Object -ComObject Microsoft.Update.Searcher
$newSearchResults = $newUpdateSearcher.Search($newUpdateCriteria)

If ($newSearchResults.updates.Count -eq 0)
{
Write-Host "I couldn't find any updates..."
Start-Sleep 5
}
Else
{
#Download updates.
$updateSession = New-Object -ComObject Microsoft.Update.Session #creates a new update session object
$downloader = $updateSession.CreateUpdateDownloader() #creates an object for downloading the updates
$downloader.Updates = $newSearchResults.Updates #assigns the objects found above to the download object
$downloader.Download() #downloads the updates

#Install updates
$installer = New-Object -ComObject Microsoft.Update.Installer #creates a new update installer object
$installer.Updates = $newSearchResults.Updates #uses the updates from the initial search to populate what to download
$installUpdates = $Installer.Install() #installs the updates

#Reboot if required by updates.

If ($installUpdates.RebootRequired -eq $true)
{
Write-Host "This computer needs to be restarted"
}
Else
{
Write-Host "Reboot NOT required!"
Start-Sleep 5
}
}
