Hibernate

In Windows XP, Microsoft combined the Standby and Hibernate buttons in the Shutdown dialog; holding down the Shift key transforms the Standby button into a Hibernate button.

Combining the two buttons makes a lot of sense; they're closely related, and hiding the less frequently used button can avoid some of the confusion between them. In some cases it can be particularly inconvenient, however. (Tablet PCs, for example, might not have a Shift key readily available!)

Hibernate.exe provides an easy and direct way to hibernate a computer. Note that this also can be done by running:

rundll32.exe PowrProf.dll, SetSuspendState Hibernate

The only difference is that Hibernate.exe asks for confirmation first.

Hibernate [--now]
Hibernate -h
