Compare Hotfixes on Server using Powershell

I came across this script on the Powershell Code Repository site. Props to the author as this is very helpful. I am showing the code below as sometimes hitting the community site is very slow:

Function Compare-InstalledHotfix {
param (
[parameter(Mandatory=$true,Position=0)]
$server1,

[parameter(Mandatory=$true,Position=1)]
$server2,

[parameter(Mandatory=$true,Position=3)]
[Management.Automation.PSCredential]
$credential
)

$server1HotFix = get-hotfix -computer $server1 -Credential $credential | select HotfixId
$server2HotFix = get-hotfix -computer $server2 -Credential $credential | select HotfixId

$comparedHotfixes = compare-object $server2HotFix $server1HotFix -IncludeEqual

$result = @();

foreach ($c in $comparedHotfixes) {
  $kbinfo = "" | select KB,$server1,$server2
  $kbinfo.KB = $c.InputObject.HotfixId
  switch ($c.SideIndicator)
  {
  "==" {
          write-host -ForegroundColor Green "Both servers have $($c.InputObject.HotfixId)"
          $kbinfo.($server1) = $true
          $kbinfo.($server2) = $true
          $result += $kbinfo
       }
     
  "=>" {
          write-host -ForegroundColor Yellow "$server1 has $($c.InputObject.HotfixId) but $server2 doesn't"
          $kbinfo.($server1) = $true
          $kbinfo.($server2) = $false
          $result += $kbinfo
        }
      
  "<="  {             write-host -ForegroundColor Magenta "$server2 has $($c.InputObject.HotfixId) but $server1 doesn't"             $kbinfo.($server1) = $false             $kbinfo.($server2) = $true             $result += $kbinfo           }     } # End Switch   } # End foreach    $result  } # End Function
