Just a note about the keys:
HKEY_LOCAL_MACHINE\System\CurrentControlSet is just an alias to one of the keys
HKEY_LOCAL_MACHINE\System\ControlSetXXX, where XXX is the number taken from
HKEY_LOCAL_MACHINE\System\Select\Current
The value of "Current" is set during the boot according to the configuration you select (Default / Last Known Good).
Your ControlSet001 is probably the usual configuration, ControlSet002 the Last Known Good config. So, there is not wonder that you can find the key in three copies in your registry.
Of course, that doesn't answer the question how the strange values got there...
