The Select registry key provides the number of the system's CurrentControlSet. The CurrentControlSet contains important configuration for the Windows operating system, and several different Control Sets may be available within a system's registry.
In general, ControlSet001 will be the most recent Control Set that has been booted under, whereas ControlSet002 functions as a backup of a known-good state for the Control Set.

Within the Select key, the value named Current identifies the CurrentControlSet by an integer. If the value is 1 for instance, that means that the CurrentControlSet on a live system will point to ControlSet001.
In the following example, the Select value's data is 1, indicating that the CurrentControlSet is ControlSet001.
