Microsoft Readying Vista SP1 Beta for mid-July 2007

@ 2007/07/09
Windows Vista is not even a year old, but Microsoft is already orchestrating the launch of Service Pack 1 (SP1) Beta 1 for the week of July 16. Many companies will not even touch a new Microsoft operating system until the first service pack is released, so the quick rollout of SP1 isn't totally unexpected.
