I reproduce them here - incase the site above disappears. It actually comes from - http://home.eunet.no/~pnordahl/ntpasswd/WinReg.txt. - -The windows NT registry has 2 different blocks, where one can occure many -times... - -the "regf"-Block -================ - -"regf" is obviosly the abbreviation for "Registry file".
