Unable to run DOS programs since last XP update

Hello Friends,

I have installed Windows Xp on my system. Recently i have updated my Windows Xp, i'm unable to run Dos Program on my system. When i try to run DOS program from CMD window or directly by clicking on the DOS icon, i only get the frozen DOS window.:crybaby: I don't know what happen suddenly, but it used to work fine before i had updated my operating system. Does any one have any idea about this issue? Can any one help me out to resolve this problem? Any kind of help would be appreciated.

Thanks in advance.

Below are some solutions of how to trouble shoot:

Solution 1:-

Make a search of the file autoexec.nt under C: \ windows \ repair and copy same in C: \ Windows \ system32. View the properties of this file and check the read-only

Solution 2:-

You can extract the file autoexec.nt from the windows XP CD installation. Run the CD from your drive and from MS-DOS prompt, type the command:

expand D: \ i386 \ autoexec.nt_ c: \ windows \ system32 \ autoexec.nt

View the properties of this file and check the read-only

Try to download MS-DOS based 16-bit Windows application on Windows XP.

16-bit MS-DOS Subsystem Path to the program that you are trying to start or install C:\Winnt\System32\config.nt The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application.

or

16-bit MS-DOS Subsystem path to the program that you are trying to start or install 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.

When it is downloaded, double-click it to run it. It reinstalls the missing or corrupt XP system files command.com, autoexec.nt and config.nt which cause the error.
