• I happen to use an Windows NT system. Can you give me some hints?
    Windows NT (or, WinNT) is Microsoft's attempt to catch up to Unix's multiuser environment (which has been around since the early 70's). Of course, Microsoft still doesn't get it right but that is another story. Each user has his or her own ``user profile'' that is usually stored in the folder C:\winnt\profiles\<usr-name>. Thus, your will find that your desktop files and start menu are stored here.

    Two basic files in DOS, namely CONFIG.SYS and AUTOEXEC.BAT, are used to configure your system. But in WinNT, these files are called CONFIG.NT and AUTOEXEC.NT and are found in the directory

    /%systemroot%/System32,
    where %systemroot% is where WinNT system information are found (e.g., %systemroot%=WINNT). Config.nt (not config.sys) and autoexec.nt (not autoexec.bat) are used to initialize your MS-DOS environment, unless some different startup files are specified in the application's PIF.

    echoconfig: By default, no information is displayed when MS-DOS environment is initialized. To display information, add the command echoconfig in the config.nt/autoexec.nt files.

    ntcmdprompt: When you return to the command prompt from a TSR or while running a MS-DOS application, WinNT runs command.com (see above) This allows the TSR to remain active. To run cmd.exe (the WinNT command prompt) rather than command.com, add the command ntcmdprompt in CONFIG.NT or other startup file.

    dosonly: By default, you can start any application from command.com. But if you start an application other than MS-DOS application, any running TSR may be disrupted. To ensure that only MS-DOS applications can be started, add the command dosonly to config.nt or other startup file.
