Get all updates installed on a Windows system

- Reading time: ~1 minute

Windows patching is so much more complicated than Linux (yum install -y :)

Here is a script to list all applied patches on a Windows ssystem:

$Session = New-Object -ComObject "Microsoft.Update.Session"
$Searcher = $Session.CreateUpdateSearcher()
$FormatEnumerationLimit=-1
$historyCount = $Searcher.GetTotalHistoryCount()

$Searcher.QueryHistory(0, $historyCount) | Select-Object Title, Description, Date, @{name="Operation"; expression={switch($_.operation)
{

        1 {"Installation"}; 2 {"Uninstallation"}; 3 {"Other"}

}}} -ExpandProperty Title > C:/Temp/ListOfWindowsUpdates.txt

Feedback is of utmost importance, how will you know if yo uare i nthe right direction without feedback? My company gave me a questionnaire to gather the feedback:

  1. When you think back on your last few months at <Company_Name>, what went well, and what accomplishments are you proud of?
  2. In reflection, what went not so well for you?
  3. And now, with the wonderful benefit of hindsight what would you do differently next time? What could <Company_Name> have done to assist further?
  4. What support do you need from us this year?
  5. In the year ahead, what are your TOP 3 areas of focus and how do you believe these will make a difference to you and <Company_Name>?
  6. Your Training and Development Plan for 2017-2018?
