Here is another one liner from PowerShell 🙂 In order to get list of installed hotfixes or service packs on local or remote computers.
To get list of hotfixes on four remote computers
Get-HotFix -ComputerName pc1, pc2, pc3, pc4
To get info on installed service packs on the remote four computers
Get-HotFix -Description "Service Pack" -ComputerName pc1, pc2, pc3, pc4
I have just noticed there is a new book – Windows PowerShell 2.0 Bible on Amazon – great resource for your daily use.
