Angus Kidman at ZDNet Australia reports Microsoft unveils Freeze Dry for Windows Vista:
… senior product manager Amy Stephan offered a preview of the Freeze Dry technology.
Many IT managers plan to automatically install patches and updates on machines during periods when they are inactive, such as overnight or on weekends. However, as some patches require machines to reboot, users who leave documents open and unsaved run the risk of losing that data if the machine is automatically updated.
Freeze Dry eliminates that problem by automatically saving application state and documents and then restoring them once the system restarts, Stephan said.
