Abstract: Operating system states capture and loading technique embodiments are presented that involve the capture and loading of baseline system states. This is accomplished, in one embodiment, by storing the states of a computer's operating system memory that it is desired to restore at a future time. No changes are permitted to the persisted storage associated with the computer. Instead, changes that would have been made to the persisted storage during an ensuing computing session, had they not been prevented, are stored in a separate computing session file. Whenever it is desired to return the operating system to its baseline condition, the stored baseline system memory states are loaded into the operating system memory, in lieu of the operating system memory's current states.
