NOTE
: Removing these additional keys requires manipulation of the rights on those
keys. The default rights for Everyone is READ. This needs to be done for each key you
wish to remove. To change the rights, log on as Administ
rator, run Regedt32.exe, and
select the key you want to delete. From the menu, select Security, Owner, Take
ownership. Then, Select Security, Permissions, and give full control to Everyone,
selecting "Replace permission on existing subkeys."


Reboot the c
omputer so that Registry changes are recognized by Windows NT.
