As Mary Jo Foley forecasted, a Windows Vista SP1 drop was made in mid-July. We're hearing, however, the drop was made to a small group of random testers for "pre-beta" testing. Pre-beta testing is usually conducted to test software that is more mature than a first-stab, annihilate-your-machine alpha (VS2008 anyone?) but doesn't quite implement all the required functionalities to be labeled a true beta.
The service pack comes labeled with a build string matching its recently released WDK brother and smells of Server 2008 kernel, which is A Good Thing™ -- 6001.16549(longhorn_sp1beta1.070628-1825). (Thanks C.)
Queried Microsoft and beta participants are denying the program's existence, as expected. We'll have to suffer with our malfunctioning Windows Vista installs for just a tad longer.Microsoft, Windows Vista, Vista SP1, SP1, Vista News, Microsoft News
