One of the things that keeps some companies from patching computers in a timely fashion is the potential for data loss if a computer being patched restarts and data open on the desktop is lost.

Windows Vista promises to fix that problem by “freeze-drying” any work open on the PC at patch time, allowing the user to reconstitute the work when the computer restarts.

Even better, they’re making the patching process better, so restarts will be necessary much less often. Many apps can be patched while they’re running, and are replaced at next restart. We have some of that now, but will have more of it in the Vista release.
