When I start "Windows XP SP2 home" the following message pops up on the
desktop.

16-bit Windows subsystem
C:\Windows\system32\autoexec.NT. the system file is not suitable for running
MS-DOS and Microsoft Windows
applications. choose "close" to terminate the application

I believe it started after trying to get an old programme to run - "Red
Ace".
I told it to run as Windows 95 but without success and I then deleted the
programme.
I would appreciate any help to stop this happening.

More than likely AUTOEXEC.NT is missing or corrupt. Go to \windows\repair
and copy the autoexec.nt you find there to windows\system32
 
AUTOEXEC.NT Fix Method 1:
copy; c:\windows\repair\autoexec.nt
to
c:\windows\system32


AUTOEXEC.NT FIX Method 2:
Go to; Start --> Run
enter; cmd.exe

{ assuming the WinXP CDROM disk is in drive "D:" }
In the Command Prompt enter...
expand D:\i386\autoexec.nt_ %windir%\system32\autoexec.nt


Since there are many forms of malware that can cause a problem with AUTOEXEC.NT, please
perform the following...


1) Download the following three items...

Trend Sysclean Package
http://www.trendmicro.com/download/dcs.asp

Latest Trend Pattern File.
http://www.trendmicro.com/download/pattern.asp

Adaware SE (free personal version v1.05)
http://www.lavasoftusa.com/

Create a directory.
On drive "C:\"
(e.g., "c:\New Folder")
or the desktop
(e.g., "C:\Documents and Settings\lipman\Desktop\New Folder")

Download Sysclean.com and place it in that directory.
Download the Trend Pattern File by obtaining the ZIP file.
For example; lpt371.zip

Extract the contents of the ZIP file and place the contents in the same directory as
sysclean.com.

2) Update Adaware with the latest definitions.
3) Disable System Restore
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm
4) Reboot your PC into Safe Mode
5) Using both the Trend Sysclean utility and Adaware, perform a Full Scan of your
platform and clean/delete any infectors/parasites found.
(a few cycles may be needed)
6) Restart your PC and perform a "final" Full Scan of your platform using both the
Trend Sysclean utility and Adaware
7) Re-enable System Restore and re-apply any System Restore preferences,
(e.g. HD space to use suggested 400 ~ 600MB),
8) Reboot your PC.
9) Create a new Restore point

Hi George - Try this fix, courtesy of MVP Kelly Theiriot:


"This installaton program will reinstall the missing or corrupt Windows XP
system files command.com, autoexec.nt and config.nt. The absence or
corruption of one or more of these files causes a "16 Bit Subsystem" error.

XP_Fix.EXE by TRF Systems, Inc.
http://www.visualtour.com/downloads/xp_fix.exe

More info here:

Error Message: MS-DOS or 16-bit Windows-based program
http://www.kellys-korner-xp.com/xp_m.htm#16bit"


Then, courtesy of flrman1, here:

"First in safe mode click on My Computer then click Tools > Folder Options.
In Folder options click on the View tab. Under Files and Folders tick "Show
hidden files and folders" then uncheck "Hide file extensions for known file
types" and uncheck "Hide protected operating system files (recommended)".
Now click "Like current folder" then "Apply" and "OK"

Now find and delete these files:

C:\WINNT\system\windupdate.exe (added by JB: note the spelling - the
added 'd')
C:\WINNT\system.css

Delete this folder:

c:\freescan

Also in safe mode navigate to the C:\Windows\Temp folder. Open the Temp
folder and go to Edit > Select All then Edit > Delete to delete the entire
contents of the Temp folder.

Go to Start > Run and type %temp% in the Run box. The Temp folder will open.
Click Edit > Select All then Edit > Delete to delete the entire contents of
the Temp folder.

Finally go to Control Panel > Internet Options. On the General tab under
"Temporary Internet Files" Click "Delete Files". Put a check by "Delete
Offline Content" and click OK. Click on the Programs tab then click the
"Reset Web Settings" button. Click Apply then OK.


Empty the Recycle Bin"


Run the fix file again after you're done w/the above.
