Process File: ntvdm or ntvdm.exe
Process Name: Windows 16-bit Virtual Machine
Description: The Windows Virtual Machine for 16-bit Windows and Dos programs is used to run dos programs and old Windows programs inside a virtual machine
Common Errors: N/A
System Process: No
-----------------------------------------------------------------------------

So if you don't run any 16-bit programs, you can safely disable it from the startuplist.

Commented:
16 bit programs are dos programs, old games (win95 and lower) so if you don't use any of them, just disable them.

You can ask a question at CS to reopen this question so you can give the points to Sunray_2003
I could also make a question to give points to sunray_2003 if you both agree on that.

Sweet!  I searched for hours before I found this answer that used TameDOS... I *hate* running DOS progs, but it is a necesaary evil for now.  
Thanks!

I found detailed description about ntvdm.exe in this site http://www.2-spyware.com/file-ntvdm-exe.html
It is required for stability.

Commented:
hello

i have the same problem....cpu on 100%
but i dont wont to pay for a tool where i cant read the sources.
gives any other way to reduce the cpu usage?

thanks.
Best free system analyzer I've seen, and real easy to use:
http://www.sysinternals.com/Utilities/ProcessExplorer.html

Don't know if that's exactly what you mean, but for instance it actually shows you which prog. started ntvdm.exe if you select Tree View or Rightclick +Properties for ntvdm.exe

It helped me anyhow to get to which program caused the problem
Oh, and that http://www.sysinternals.com/Utilities/ProcessExplorer.html

also gives easy option to kill ntvdm.exe and get system performance back

Commented:
If you need to run a dos program, i recommend using DOSBox, it's easy to setup & configure, it will fix your high CPU usage problem.
