"eWEEK Labs has been testing Microsoft Windows Vista builds for more than three years, and our evaluation of the final code shows that the new operating system is a
significant improvement over its predecessor, Windows XP. What's more, with a raft of subsystem and driver model improvements, Microsoft has laid out in Vista a solid foundation for stability and usability gains in future Windows versions. For enterprises running XP on their desktops and notebooks, however, a Vista upgrade is no slam-dunk. While Vista's new UAC facilities can make it easier for companies to appropriately lock down their desktops, for instance, it's quite possible to run a well-managed shop of XP machines, either out of the box or with the aid of lockdown tools."
