RE: About default sharing folders in Windows

Can't delete Administrator or Guest.  Rename & Disable them, then create dummy
accounts with those two default names.  All acl's are checked against the SID's not
the actual name and the SID's won't change with a rename.  Therefore if you can't
delete it and renaming it won't remove the assignments, you're hosed.  There are
tools out there that will scan your filesystem for rights, can't remember any just
now.  Audit the system and manually remove rights.

how about deleting the admininistrator  account (killing that sid)
recreating a new account, redoing the privileges for that account,
and adding the new username to the administrator or appropriate group.

then 'hack the registry'  :D

then you should be left with a box with no default shares,
administrator/guest default accounts are non-existant, and the new ones
have new SIDs.

that a possible solution?

oh yeh,   this is my first post  :D

It is best to "disable" the built in administrator account.

I strongly suggest renaming the local Administrator and Guest account
to something that is not easily guessed at.  In addition, you should
probably create "dummy" accounts named "Administrator" and "Guest"
that have no rights/no group memberships and are disabled.  Monitor
the dummy accounts closely for log in attempts.

  Note that there's no point to this unless you *also* disable the ability
to enumerate accounts over a null connection.  The renamed Administrator
account will be trivial to spot by its ID otherwise.
