Differences between ControlSet001, ControlSet002, and CurrentControlSet

The differences between ControlSet001, ControlSet002, and CurrentControlSet are recorded in SYSTEM service settings in [HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Services \ TermService. Www.2cto.com what are the differences between ControlSet001, ControlSet002, and CurrentControlSet? By default, ControlSet001 indicates the actual configuration information of the system. CurrentControlSet: runtime configuration. When windows is started, a copy is copied from ControlSet001 as the current configuration information of the operating system. All the modifications made to the computer configuration are directly written to CurrentControlSet. During the restart process, windows overwrites ControlSet001 with the content of CurrentControlSet to ensure that the two control groups are consistent. ControlSet002: configuration information of the last successful startup. Each time the operating system starts successfully (A Successful Logon), it copies data in CurrentControlSet and ControlSet001 to ControlSet002. -------------------------------------------------------------------------- However, the order and number are not the same, and the change occurs after "Last correct configuration" is used. At this time, the system regards 002 as the actual configuration information of the system, and the control group with 001 problems will be backed up and stored. [HKEY_LOCAL_MACHINE \ SYSTEM \ system \ select] records the configuration to be used next time: "Current" Data project indicates the control group used by Windows during this startup. The "Default" data item indicates the control group that Windows will use at the next startup. It is the same as the control group used for this startup. The "LastKnownGood" Data project indicates the control group that Windows XP uses when you select "Last correct configuration" during startup. The "Failed" data item indicates the control group in which Windows XP fails to save the data generated by startup. This control group does not exist until the user calls the "Last correct configuration" option for the first time.
