Windows Vista, the next version of Microsoft’s operating system, introduced a new patching technology code-named Freeze-Dry which reduces the number of required restarts and store user data before reboots.

On Friday, a representative from Microsoft describe that Freeze-Dry technology uses a new restart manager in Windows Vista. In most cases, consumers won’t have to restart Windows Vista when installing or updating an application.

Furthermore, it will even be possible to patch some applications while they are in use. “Windows Vista automatically replaces the file the next time the application is restarted,” the Microsoft representative said. Windows Vista, previously code-named Longhorn, is due out by the end of next year.

The Freeze-Dry on Windows Vista also ensure user data safety when an application restart is required after patching. Windows Vista will automatically save the person’s data, close the application, apply the patch and restart the application, Microsoft said. “As a result, most updates need not interrupt users’ work,“.

Unlike Windows Update, Microsoft Update provides patches for a number of the company’s products, not just the Windows operating system. That means customers no longer have to visit several Microsoft Web sites to make sure they have the latest fixes for each product.
