Fast computer startup

摘要

Fast computer startup is provided by, upon receipt of a shutdown command, recording state information representing a target state. In this target state, the computing device may have closed all user sessions, such that no user state information is included in the target state. However, the operating system may still be executing. In response to a command to startup the computer, this target state may be quickly reestablished from the recorded target state information. Portions of a startup sequence may be performed to complete the startup process, including establishing user state. To protect user expectations despite changes in response to a shutdown command, creation and use of the file holding the recorded state information may be conditional on dynamically determined events. Also, user and programmatic interfaces may provide options to override creation or use of the recorded state information.

主权项

1. A method performed on a computing device, the method comprising:
first executing, by the computing device, a first shutdown sequence that is configured to shut down the computing device; waking, by the computing device without user intervention, the shutdown computing device; performing, by the woken computing device without user interaction, a maintenance activity on the computing device; restarting, by the computing device without user intervention in response to the performing, the computing device; second executing, by the restarted computing device, a second shutdown sequence without user intervention, where the first shutdown sequence and the second shutdown sequence each comprise:
breaking down any user session or sessions established on the computing device;copying system state information of the computing device to non-volatile memory, where the copied system state does not include user state information pertaining to the broken-down any user session or sessions; andpowering down at least a portion of the computing device.
