Note: You may see a different combination of numbered control sets. Typically, only two control sets are stored in the SYSTEM subtree, but there can be up to four. The numbers may or may not be sequential. For example, another computers can contain the SYSTEM subtrees ControlSet001 and ControlSet003. For the sake of discussion, I’ll use ControlSet001 and ControlSet002 in the examples.  

The ControlSet001, ControlSet002, and Clone keys all contain complete copies of the required boot information in what are called control sets. One of the numbered control sets is used by default to boot the computer (in this case, ControlSet001), and the other contains the Last Known Good configuration (in this case, ControlSet002).  

For administrative convenience, CurrentControlSet is a pointer to whichever control set was used to boot the computer. In this case, CurrentControlSet points to ControlSet001
