Hi there

I am using Windows XP at work and I realised that nvdm.exe is all available cpu usage when I first log onto my PC.  I can end the process to avoid the drainage of my CPU resources but when I use msconfig.exe I cannot find ntvdm.exe from startup list, may I know how I can disable it ?

Please kindly advise ASAP.

    ntvdm is the NT Virtual Dos Machine.  When you run DOS programs or Windows 3.1 applications, they use NTVDM.  I'd suggest try figuring out what application is using the NTVDM and stop using it - or if you can't, just lower the priority of the NTVDM process.

    Hi leew

    Thanks for your prompt reply. I had used a program called "Tame Version 5.0" and find out I am not using any DOS program, may I know how can I the priority of the NTVDM process on my XP PC then ?

    Please kindly advise.

    Just open up task manager and find the NTVDM process.  Then right click it and change the priority.

    You may be using a Windows 3.1 utility and not realize it.  Review everything you have starting up and use MSCONFIG to disable everything and reenable a few at a time.  You'll eventually find what is causing NTVDM to run and you can decide if you need it or not.

    Hello leew

    I think I will use msconfig to disable everything and re-enable one at a time and at least to have a chance to find out what causes the problem.
