Default Re: Resetting C-drive permissions w/o damaging data, apps, user pr

You can go ahead an use secedit as described in the KB but you may find that
user/group permissions that you had defined to be other than default
probably will be changed back to default which is a fairly secure setup but
may deny access to non default groups that you have added. An administer
will be able to logon to run/configure applications and manage ACLs. ---
