When I tell people that I'm testing a prerelease version of Windows, the first question they inevitably ask is, "Is it faster than [insert their current Windows version here]?" Everybody wants Windows to run faster, but that's primarily because most of us are running systems that have had the same OS installed for several years. One of the bitter truths of computing is that even the most meticulously well maintained system will slow down over time. On such systems, the only surefire way to get a big performance boost is to wipe the hard drive and start with a fresh OS install.

The Windows Vista Setup program essentially does just that (preserving and restoring your files and settings along the way, of course). So the short answer to the previous question is, "Yes, Vista will be faster than your existing system." However, that performance gain comes not just from a fresh install, but also because Microsoft has tweaked the Windows code for more speed:

• Faster startup Microsoft has optimized the Vista startup code and implemented asynchronous startup script and application launching. This means that Vista doesn't delay startup by waiting for initialization scripts to complete their chores. It simply completes its own startup tasks while the scripts run in their own good time in the background.

• Sleep mode Actually, you can reduce Vista startup to just a few seconds by taking advantage of the new Sleep mode, which combines the best features of the XP Hibernate and Standby modes. Like Hibernate, Sleep mode preserves all your open documents, windows, and programs, and it completely shuts down your computer. However, like Standby, you enter Sleep mode within just a few seconds, and you resume from Sleep mode within just a few seconds.

• SuperFetch This technology tracks the programs and data you use over time to create a kind of profile of your disk usage. Using the profile, SuperFetch can then make an educated guess about the data that you'll require; like XP's Prefetcher, it can then load that data into memory ahead of time for enhanced performance. SuperFetch can also work with Vista's new ReadyBoost technology, which uses a USB 2.0 Flash drive as storage for the SuperFetch cache, which should provide improved performance even further by freeing up the RAM that SuperFetch would otherwise use.

• Restart Manager This feature enables patches and updates to install much more intelligently. Now you often have to reboot when you install a patch because Windows can't shut down all the processes associated with the application you're patching. Restart Manager keeps track of all running processes and, in most cases, can shut down all of an application's processes so that the patch can be installed without requiring a reboot.
