How does CurrentControlSet differ from ControlSet001 and ControlSet002?

windows registry

Yes, you only need to update the CurrentControlSet key...

ControlSet001 and ControlSet002 are alternating backups ofCurrentControlSet, you don't need to update them.

Edit: As K noted, CurrentControlSet is an alternating symbolic link to eitherControlSet001 or ControlSet002. The other key is kept as a backup for theLoad Last Known Good Configuration boot option.

Edit 2: See Microsoft KB Article 100010: What are Control Sets? What is CurrentControlSet?
Original page link broken, see archive.org backup page instead.

CurrentControlSet is technically not a "backup" as Gordon states.
It is a symbolic link to one of the ControlSets on the computer. It alwayspoints to the ControlSet that is currently loaded.

Actual symbolic link match is in: HKEY_LOCAL_MACHINE\SYSTEM\Select\.
