Windows XP and Vista Service Packs
Looks like Microsoft has released beta versions of the service packs for Windows Vista and Windows XP.
Shhhh! Pre-beta Vista SP1 is out there Over the past couple of days, there have been new reports of sightings of the pre-beta of Windows Vista Service Pack (SP) 1. The reported build number: 6001.16549 (longhorn_sp1beta1.070628-1825). I?ve been getting tips over the past couple of weeks from testers who said they had the promised pre-beta. The tipsters all were referencing different build numbers. My first guess was the secrecy-obsessed Windows Vista team might be providing different testers with different build numbers in order to trace leaks.
Windows XP SP3 Released To Small Group (Updated) In addition to the previously reported Windows Vista SP1 drop to testers, Microsoft has just recently (few days ago) dropped a copy of Windows XP Service Pack 3 in the lap of the same small group of testers. Coming in at less than 350MB, the service pack includes fixes for over 900 reported problems, some of which have already been resolved with post-Service Pack 2 hot fixes. For the hardcore build string collectors, this build is tagged 5.1.2600.3180 (xpsp.070718-2058).
They have included several screenshots of both service packs.
