It's the first part of the most common pirate activation code for Windows XP. It's been around since XP was released (and even before that), so Microsoft blocked the SP1 update for the people who use it.
Horary...for us Windows XP Service Pack 2 Beta testers. There a new build available to download now with loads of fixes and new features. One of them is a Security Center like Mcafee Security Center, which informs of your firewall, auto-update and anti-virus Status. If you want to check out some pictures of it, check at Neowin and I should have some up tomorrow once its finish downloading.
Tester Beware of the network install size: 345.4MB. [Hence the big size because it can be applied to Media Center Edition and Tablet PC's]
well i had a link to download it off micro$oft, didn't tho b/c i didn't want it scrtewin my comp, being beta and all, is it decently safe, like not toooo bugy and does it actually have this 180day thing?
unless ur a tester, theres no reason to try and upgrade. its not drastically different, and no REAL feature changes. i dont see why everyone wants to rush to get it.
