As time goes on, you will see more references to WinRM, especially with Windows Server 2008. Windows 2003 R2 had a form of WinRM that has now been updated to support the WS-Management industry standard.
Who should be interested in this? People that manage servers remotely and need a firewall friendly protocol to use. People that are looking into deploying Windows Server 2008 and especially Windows Server 2008 Core. People that need to interface with the BMC adapters on servers from remote.
Anyway, KB 936059 updates Windows XP SP2 and Windows Server 2003 WinRM components to bring them more in line with what Windows Vista and Windows Server 2008 are using.
