Brett Zehr was surprised on Thursday when he saw that his Windows Vista PC had a new update ready: Service Pack 1. Although the product wasn"t supposed to be available until mid-March, a glitch on Thursday meant that he and some other general users were able to download the Vista update. The update was not pushed out via Windows" Automatic Update feature, but was listed for owners running the 64-bit version of Vista who chose to "check for new updates" via Windows Update.
"A build of SP1 was posted to Windows Update and it was inadvertently made available to a broad group," Microsoft said in a statement. "The build was intended only for our more technically advanced testers, and was meant to only be offered to those with a specific registry key set on their PC. For general availability, we are still planning to make SP1 broadly available in the mid-March timeframe."
