MS-DOS subsystem also records an MRU list, good only for the
                            life of a Command Prompt session. (To reexecute a command in a
                            Command Prompt window, press F7 and select from the menu.)
                            In  addition  to  these  MRU  lists,  Windows  helps  you  reenter
                            commands in a variety of other ways. The History bar in Windows
                            Explorer  and  Internet  Explorer,  for  example,  keeps  a  record  of
                            your  activities  that  covers  the  most  recent  three  weeks.  The
                            Documents  menu  maintains a  list of  your 15 most recently used
                            documents  (shortcuts  to  many  more  than  15  are  kept  in  your
                            Recent  folder),  and  the  common  dialog  boxes  (the  File  Open
                            dialog box in Microsoft Word, for example) have their own built-
                            in historians.
                            All  this  convenience  might  occasionally  prove  inconvenient  -
                            particularly if you're reluctant to have your colleagues know about
                            every Web site you happen to visit. You can hide your tracks from
                            casual onlookers by locking your workstation whenever you leave
                            your  desk.  (Press  Ctrl+Alt+Delete  and  choose  Lock  Computer.)
                            Under ordinary circumstances you can make your history invisible
                            to other user accounts by putting the sensitive data on an NTFS
                            volume and using file and folder permissions settings to ward off
                            intruders.  For  good  measure,  you  can  also  apply  NTFS  file
                            encryption  to  folders  you're  concerned  about.  Encrypting  and
                            restricting  access  to  your  %UserProfile%  folder  and  all  its
                            subfolders  will  keep  casual  snoopers  out  of  your  History,
                            Temporary Internet Files, and Recent folders - provided, of course,
                            that you haven't moved those folders from their default locations.

                                                  Start at Logon

                            After  Windows  2000  starts,  it  can  automatically  launch  any
                            number  of  programs  and  services.  You  can  find  -  and  add  or
                            delete, if desired - the programs that start in any of the following

                               any of these programs, you can edit the Start menu directly, or
                               you    can   use    Windows     Explorer    to   navigate   to
                               %UserProfile%\Start Menu\Programs\Startup.
