Listing the Updates of the Servers under a Certain "OU"

$OU= "OU=MUHASEBE,DC=guler,DC=com"

foreach ($Serverlist in (Get-ADComputer -Filter * -SearchBase $OU | select name).Name)
{
"Servername: "+ $Serverlist
Get-Hotfix -cn $Serverlist | Select HotfixID, Description, InstalledOn, ServicePackLevel
" "
}

This PowerShell script gets the list of computers in the Organization Unit named "ACCOUNTING" in the "guler.com" domain. Then it shows the server name and installed hotfixes for each server.
