Select Registry Key

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.

Artifact Interpretation

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.
