KB2749655 not available in 'All Software Updates'

Hi,

Can someone please explain why the KB2749655 for Windows 7 is not available in SCCM. We would like to include this in our baseline, but it is not available and therefore cannot be added.

I can see the Windows XP, Server 2003 versions, but not Windows 7 and just wanted to know why and if there is a way to include this with the standard baseline we rollout to all desktops.

Thanks
