Thanks to bLaCKcOmB who has informed us that a newer internal release of SP1 has somehow leaked to the web, this time carrying build number 1070. Unlike the first betas this one carries no significant changes at all and doesn't even include Windows Messenger 5.0 -damn, ah well.
Microsoft will probably release the final "End-user" SP1 (also called RTW) in August allowing XP users to update Windows and customize it's native media components to anything they like, whether or not this is a fine plan remains to be seen. I dread seeing (or not seeing) dialogs asking if I want to: "Change default Media Player to [insert name here]"
There are no documents on the Windows XP web that explain the new "Set Programs" feature if anyone has more info on this please drop a comment and who knows we'll have a closer look at it.
Oh, there are no links yet and seeing as we cant host it, we'll keep you posted if anyone else decides to host it.
