Following my previous thread "Can I access MS DOS from my Windows 10 platform?", following the help I received in that thread, I have had DOSBox running fine until today. I think there was an automatic Win 10 update in the intrum. Whether that is the cause I'm not sure, but now DOSBox crashes every time I try to run it. Here is what I do:

As shown I 'mount' the destination location and then go to the DOSBox c drive. Then when I try to open my GW BASIC operating program, (b.exe), it does nothing for a few seconds and then shuts down, returning me to the Win10 desktop.

I'm definitely not doing anything different to previously as I had put the above shown commands into ShortKeys and have been accessing successfully using the shortcuts for a full day. Now it crashes. I've tried uninstalling and downloading again but it's made no difference.

Can you list the specific WIN 10 KB updates that you received. Go to Settings-> Update & Security-> Advanced Options-> View History

Security Update for Internet Explorer Flash Player for Windows 10 for x64-based Systems (KB3132372). This was on 1st January some time.
I should mention that I had an error message when booting before the problem showed itself. I couldn't boot the computer at all, with a "Cortana cannot open" message or words to that effect. After several reboot attempts the system locked up completely and I did an illegal shutdown, turning off at the wall. Next time I tried the boot was successful with no mention of Cortana at all and it's been OK since. Whether that problem was a result of the Windows update and what then caused the DOSBox problem I'm not sure. The sequence was Windows update, Cortana problem. DOSBox problem.

I've found an inconsistency when following the procedure in the screenshot above. Usually after I enter b.exe there is a pause and then DOSBox shuts down as described. Less frequently I get a flashing cursor under the entry and it doesn't shut down, but nothing further can be entered, On other rare occasions I actually get another c:\ and can enter some commands like 'dir' or 'command' and they work, but still can't find a way of opening b.exe

Well I also have received and installed KB3132372, but have not had any problems with DOSBox. I don't know about Cortana (Its turned off on my system). Maybe that is the problem ? I will attempt to test DOSBox with Cortana turned on and I will get back to you

DOSBox works on my system regardless if Cortana is running or not. With all of the issues you had after the install of KB3132372, you may want to un-install it, Try DOSBox again and then try re-installing the update and see what happens.

I've found the reason and it has nothing to do with Win10 updates or Cortana. Neither was DOSBox at fault. My destination program, (b.exe) was corrupted. I've reinstalled from my back up and it is now working fine!

Thanks for all your help storage_man, much appreciated.
