Two substantial collections of Windows Vista hotfixes leaked to the Internet after being offered to Windows Server 2008 beta testers this weekend, leading some users to speculate that the pair are actually the foundation of the future Service Pack 1 (SP1) release for the OS.
Labeled "Vista Performance and Reliability Pack" and "Vista Compatibility and Reliability Pack," the two updates feature a long list of non-security-related bug fixes, including those that improve Vista's resumption after sleep or hibernation, boost the speed of copying or moving large directories, prevent some memory corruption problems, bolster the reliability of systems upgraded from XP to Vista and increase compatibility with video drivers.
"These issues have been reported by customers using the Error Reporting service, product support or other means," the two packs' release notes said. "Installing this update will improve the performance and responsiveness of some scenarios, and improves reliability of Windows Vista in a variety of scenarios."
