How It Works:

  • Get-HotFix queries installed updates and patches on the system - it's built on the same underlying data as the Win32_QuickFixEngineering CIM class, just wrapped in a friendlier cmdlet.
  • Select-Object Description, HotFixID, InstalledOn trims the output down to just these three properties, since Get-HotFix also returns things like Source (the machine name) and InstalledBy (often blank).
  • Sort-Object InstalledOn -Descending orders the list from most recently installed to oldest - this matters here, since without -Descending the sort defaults to ascending order, and grabbing the "first" result would return the oldest update instead of the latest one.
  • Select-Object -First 1 trims the sorted list down to just that single most recent entry.
