Microsoft Update versus Windows Update
Sigh, well apparently no one in Microsoft marketing remembers the chaos caused (and still caused) by multiple versions of Windows Messenger versus Microsoft Messenger versus MSN Messenger. And it was only a year ago.
Well, anyway, you can switch your system over to Microsoft Update (I have) by visiting http://update.microsoft.com/microsoftupdate. Of course, switch only your personal computer unless your IT department has OK'ed this, yada yada. Looks like a new ActiveX control will be downloaded and you'll have Office Updates included within your Automatic BITS Updates. Shiny.
