Not offhand but what you can try is a registry snapshot program such as the
free regshot. Take a snapshot on a computer just before you enable it and
then again after you enable. Then compare the snapshots. I am sure it would
be in HKLM. Curious that you would need to use the registry as you can use
Group Policy to configure audit policy on domain computer and import
security templates configured as you need into non domain computers using
the secedit command. If you use regshot to track down user settings just
remember to make the changes in HKEY_CURRENT_USER as regshot will show the
setting but for the HKEY_USERS with the user SID.
