-----------------------------------------------------------------------------
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.

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.

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

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.
