CacheMyWork
Publisher's Description
From Microsoft:
CacheMyWork enables you to reboot Windows without losing your place in your work. It builds a checklist of currently open applications, and will restart the apps you've selected the next time you logon to the computer.
Cache My Work is useful for occasions when you need to unexpectedly reboot, such as after installing new drivers, or when Windows runs out of Desktop Heap, Handles or GDI Objects.
