Windows updates: 4 tidy up get-update

Looking at the get-update function we created earlier I wanted to tidy it up a bit.

001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033

function get-update { [CmdletBinding()]  param (   [switch]$hidden  )  PROCESS{ $session = New-Object -ComObject Microsoft.Update.Session $searcher = $session.CreateUpdateSearcher() # 0 = false & 1 = true if ($hidden){  $result = $searcher.Search(“IsInstalled=0 and Type=’Software’ and ISHidden=1″ ) } else {  $result = $searcher.Search(“IsInstalled=0 and Type=’Software’ and ISHidden=0″ ) } if ($result.Updates.Count -gt 0){  $result.Updates |   select Title, IsHidden, IsDownloaded, IsMandatory,   IsUninstallable, RebootRequired, Description } else {  Write-Host ” No updates available” }  }#process <# .SYNOPSIS Discovers available updates .DESCRIPTION Interrogates Windows updates for available software updates only. Optional parameter to display hidden updates .PARAMETER hidden A switch to display the hidden updates .EXAMPLE get-update Displays non-hidden updates .EXAMPLE get-update -hidden Displays hidden updates #> }

Primary changes are:

• to add a switch to the function to control the display of hidden updates
• count the available updates and display message if there aren’t any
• add more properties to the output- 7 properties defaults to a list so more readable as well
• add comment based help
