I would be interested to hear why on earth you want to do this, but as far as I know, you cannot hide a process from Windows - otherwise all the malware authors would be using such a technique to hide their viruses and spyware.

to hide processes from the task manager and the normal API, however you must have the "REAL" source code, and not just a wise script that is compiled. Another possibility would be to create a dll "HOOK" that explicitly intercepts such calls that display information in for example the Task Manager. I suspect however this technique will be beyond your capabilites if you ask this type of question on this forum. If you are still interested, a good starting point is www.codeproject.com
