Hi Peeps. Thought i'd let everyone know about a few values i've added to RD. Looking through DCS's website,i found this http://www.diamondcs.com.au/index.php?page=archive&id=nevershowext Which points here http://www.pc-help.org/security/scrap.htm I read these ages ago (When purchased TDS & PG) but forgot all about it. Anyway,did a search through the registry and have added the following rules. HKEY_CLASSES_ROOT\* - NeverShowExt HKEY_CLASSES_ROOT\Clsid\* - NeverShowExt HKEY_LOCAL_MACHINE\Software\Classes\* - NeverShowExt HKEY_LOCAL_MACHINE\Software\Classes\Clsid\* - NeverShowExt I've set all four to block 'Set Value' and 'Delete Value' If anyone else finds any more,then please share.
