den indeholder en del af registry\'et
\"The Windows Registry is a set of data files used to help Windows control hardware, software, the user\'s environment, and the \"look and feel\" of the Windows interface. The Registry is contained in two files in the Windows directory (in NT they are called \"hive\'s\"): system.dat and user.dat, with backup copies system.da0 and user.da0. The Registry database is accessed with regedit.exe which is in the Windows directory. Formerly, in older version of windows (before windows 9x) these functions were performed by WIN.INI, SYSTEM.INI, and other .INI files that are associated with applications.\"
