Windows Subsystem

[Guest]

When I log onto my desktop I get a box that appears titled 16 bit Windows
subsystem.
It then reads "C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not
suitable for running MS-DOS and Microsoft Windows applications. Chose close
to terminate the application."
I don't know what this is and what it trying to do.
Does anyone know how to stop it from appearing or am I missing a system file.
Thanx

Hi

Please see if the following article helps:

Program"

Thanx for the reply.
But as far as I know I am not trying to run a DOS based programme, it comes
up on its own.
Do you think I could be infected with a virus that is trying to run the
programme?
If it carries on I might do a system restore to see if it goes or any other
help will be gratefull.

I've tried the fix and it works while logged on. When computer restarts I
have to do the fix again.
I've read somewhere that it is a bug called windupdate, and to delete this
from the regestry. Have looked using regedit but can't find anything.
Can you help?

My SWAG would be that you still have WINDUPDATE.EXE and it keeps deleting
your Autoexec.nt file on boot up.

Have you done a Search on your machine for WINDUPDATE.EXE? It may be
Hidden, I honestly don't know. Delete anything you can find related to
WINDUPDATE.EXE.

=====

Open Regedit.

Start | Run | Type: regedit | OK |
Edit | Find | Paste this in the box:

WINDUPDATE

Check all three:
Keys
Values
Data

Click the Find Next button | Wait | Wait some more | A little more |
Still waiting | Yep, it may take a while | If you find WINDUPDATE |
Right click it in the right hand pane | Delete | Hit F3 to Search again |
Repeat until you find/delete all instances of WINDUPDATE

Hi again.
Have tried searching the regestry, found 1 mention of WINDUPDATE.EXE,
deleted it then searched my computer for it with no results.
Run the fix, then restarted the pc. The autoexec.nt box still comes up.
Have tried a system restore but this wouldn't work properly, don't know if I
am still infected.
Started to bang my head of the wall now!!!!

[[If this solves the problem, but then the next time you start your PC the
problem recurs, copy the files again, but this time make the files "read
only" by right-clicking on them then setting the read-only attribute under
"properties". In this case, something on your PC is changing or deleting the
files and setting the read-only attribute will prevent file modification. ]]
