Filtering Hotfix Information

All PowerShell Versions

Get-HotFix is a built-in cmdlet that returns the installed hotfixes. It has no parameter to filter on hotfix ID, though.

With a cmdlet filter, you can easily focus on the hotfixes you are after. This example returns only hotfixes with an ID that starts with "KB25":

Get-HotFix |
  Where-Object { 
    $_.HotfixID -like 'KB25*'  

Note that Get-HotFix has a parameter -ComputerName, so assuming you have the appropriate permissions, you can retrieve hotfix information from a remote computer as well.
