1. A computer-implemented process for capturing and loading operating system states, comprising: using a computer to perform the following process actions: storing states of an operating system memory of the computer that it is desired to load at a future time; preventing changes to a persisted storage associated with the computer during a computing session; storing changes that would have been made to the persisted storage during the computing session, had they not been prevented, in a separate session file, and employing data stored in the sessions file and in the persisted storage, during the computing session; and whenever it is desired to return the computer operating system to its condition when the operating system memory states were stored, loading the stored states in the operating system memory, in lieu of the operating system memory's current states.
