Quick PowerShell script to query for installed hotfix

This is a quick and dirty PowerShell script to see if the local computer has a particular hotfix installed. It takes one argument; the number of the hotfix.

$KB = $args[0]

Get-WMIObject -class “Win32_QuickFixEngineering” -namespace “root/CIMV2” | Where { $_.hotfixid -match $KB }

Enjoy.
