Windows NT Tricks

Windows NT

  Automatically log on as User When NT Boots For NT 3.51

        Use regedt32.exe, and search for the key   
     HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon.  Fill in the keys DefaultDomainName, Default UserName, and DefaultPassword with the values of the already-established Windows NT user. You may have to add the DefaultPassword key.
     Then choose Add Value from the menu and add a new key, named AutoAdminLogon. Select REG_SZ for the Data Type. Enter 1 in the String field.

Save the changes and restart. Windows NT will automatically give you a User login.

For NT 4.0:

     The above-mentioned tip might not work with NT 4.0. The easiest method is to simply download the Microsoft TWEAKUI powertoy. It has a Network tab that allows you to specify what user id and password you want NT 4.0 to automatically use for logging on during the boot process. Caution! This can pose as a security problem. Use only on standalone machines!

  Changing dual-boot options under NT4.0

    If you installed Windows NT 4.0 after Windows 95, and you choose to dual-boot, NT makes itself the default option when booting, and displays the menu for 30 seconds.
     To change these settings, click My Computer > Control Panel > System. Select the Startup/Shutdown tab. Above this tab is a list of all the boot options-select one as default. You can also set the wait time on this panel. Any further changes have to be made to the boot.ini which is located in the root of your boot partition.

  Creating a Login warning message

     To create a login warning message (something like: "For Sending and Receiving mail at SmartSurat.com only. Unauthorized use is prohibited"), do this:
1. Go to Start > Run. Type regedit (regedt32.exe) to start the registry editor.
2. Move down to  
    HKEY_LOCAL_MACHINE/Software/Microsoft/WindowsNT/CurrentVersion/Winlogin
3 Edit the following items to place the required text :
    LegalNoticeCaption
    LegalNoticeText

DOS ( Disk Operating System )

  Want more memory?

     If you have a Super VGA display and use MemMaker, you can free-up conventional memory without affecting normal operations by using the MONOUMB.386 file. Open SYSIEM.INI, add the line device=c:\dos\monoumb.386 to the [386Enh] section and save the file. Now restart your computer and run MemMaker by typing MemMaker at the DOS prompt. Choose Custom Setup; on the Advanced Options screen, answer Yes to "Use monochrome region (B000B7FF) for running programs?" You must take care as some video cards may object to this! Revert to old settings by reusing MemMaker and undoing your changes.

  Don't Share

     If you work only in Windows (not DOS), you can save a nice chunk of conventional memory by not loading SHARE; it is rarely needed, and Windows uses a program called VSHARE to do the same job. If there is a line that loads SHARE in your CONFIG.SYS, remark it out by using REM and see all the software that you normally use works fine. If so, you could delete the line.

  Undo MemMaker

     If you run MemMaker with a disk compression program such as Stacker or SuperStor, it won't undo changes in the CONFIG.SYS and AUTOEXEC.BAT files if it fails to restart your computer. To restore your computer to its previous state, quit MemMaker, and copy and rename the AUTOEXEC.UMB and CONFIG.UMB files from the host drive to the compressed volume. For example, if drive D is the uncompressed host drive and drive C is the compressed drive, you would type: copy d:\autoexec.umb c:\autoexec.bat and then, copy d:\config.umb and C:\config.sys.s

  Memory usage info

     If you want more information when refining your computer's memory usage, hold down the Alt key during reboot to initiate a display of start-up information.

Windows 3.1

  Swap management

     Limit the size of your temporary swap file, add a line such as MinUser[]DiskSpace=4096 to the [386Enh] section of the SYSTEM.INI file.
     This doesn't actually set the size of the swap file, this additional line limits the file's growth so that at least 4 MB of disk space remains available for use by your applications'.

Go Back

  32-bit access

     If 32-bit file access presents a problem for a DOS application, you may get a message that says, "Application has violated system integrity."
     If you get this message often, open Control Panel's Enhanced applet, click on the Virtual Memory button and then disable 32-bit file access. If that solves your problem, there is indeed a conflict between 32-bit file access and the application.

  Share Bookmarks

     Share your bookmarks and annotations with someone else who has the same help file. If you have created any bookmarks, there will be a WINHELP.BMK file in the Windows directory. Send it to someone with the same help file and they will have your bookmarks. Delete it and your bookmarks go away

  Extra-Time

When Windows has trouble talking to your printer, try changing the DeviceNotSelectedTimeout setting in the [Windows] section of your WIN.INI file. This setting defines how long Windows wili wait for a device-like a printer-to respond before delivering an error message.
