CautionHKLM\SYSTEM\
The Select subkey contains entries that specify which control set is used to start the system. The entries record which control set was used to start the system this time, which control set will be used to start it next time, and which control sets have failed to start the system in the past.
Caution
Do not change the value of this entry. The Select subkey is maintained by Windows 2000, and should not be changed by users.
