used to have trouble. I am getting an error message.
"16 bit windows subsystem

CONFIG.NT FROM THE WINDOWS XP SOFTWARE THAT CAME FROM MY SYSTEM ? HOW
DO I DO THIS? CHORD
THE FOLLOWING WAS A CUT AND PASTE FROM MICROSOFT. LOOK AT MY QUESTION

CAUSE
This issue may occur if one or more of the following files are missing
or damaged: • Config.nt
• Autoexec.nt
• Command.com
RESOLUTION MY QUESTION DO I USE MY WINDOWS XP SOFTWARE AND COPY THE
CONFIG.NT FROM THERE? Chord
To resolve this issue: 1. Insert the CD into the CD drive or DVD
drive.
2. Click Start, and then click Run.
3. In the Open box, type cmd, and then click OK.
4. At the command prompt, type the following commands, pressing ENTER
after each command:
expand CD-ROM Drive Letter:\i386\config.nt_
c:\windows\system32\config.nt expand CD-ROM Drive
Letter:\i386\autoexec.nt_ c:\windows\system32\autoexec.nt expand
CD-ROM Drive Letter:\i386\command.co_ c:\windows\system32\command.com
exit
5. Start or install the program. If the issue is resolved, do not
complete the remaining steps. If the issue is not resolved, go to the
next step.
6. Note: The Command.com file is not edited or created in this in the
following process. Because of this, you may have to expand it from
your Windows XP CD-ROM.
Start Notepad.
7. In Notepad, type the following entries: dos=high, umb
device=%SYSTEMROOT%\system32\himem.sys
files=40
8. On the File menu, click Save As.
9. In the File Name box, type Config.nt, and then click Save. Close
the Config.nt file.

12. On the File menu, click Save As.
13. In the File Name box, type Autoexec.nt, and then click Save. Close
the Autoexec.nt file.
14. Start Windows Explorer. Locate the Config.nt file, right-click the
Config.nt file, and then click Copy.

file, and then click Copy.
