PowerShell - Windows Update report to .CSV

A while back I was asked by my boss to come up with a way to get a report of all the Windows Updates installed on a remote server that is at a client's site and that we do not have access to.

I thought to myself that he must be crazy to think that we could even find a utility that would enable us to do that.

Well..... Apparently with the right Power Shell Commands you can do it. Here is the Syntax for the Script that you will need to save as a .ps1

$Session = New-Object -ComObject "Microsoft.Update.Session"
$Searcher = $Session.CreateUpdateSearcher()
$historyCount = $Searcher.GetTotalHistoryCount()
$Searcher.QueryHistory(0, $historyCount) | Select-Object Date,
   @{name="Operation"; expression={switch($_.operation){
       1 {"Installation"}; 2 {"Uninstallation"}; 3 {"Other"}}}},
   @{name="Status"; expression={switch($_.resultcode){
       1 {"In Progress"}; 2 {"Succeeded"}; 3 {"Succeeded With Errors"};
       4 {"Failed"}; 5 {"Aborted"}
}}}, Title | Export-Csv -NoType "$Env:userprofile\Desktop\Windows Updates.csv"

The result looks something like this:

I hope you find this post helpful and are able to use this going forward.
