Protecting Executables from caching

By les.h.clark ·
I have an executable running in RAM on a laptop. The executable is of a very sensitive nature and must never be written to the local machine's disk.

How do I do this? Is there a simple registry key or some such that I can set that will allow the NT OS to execute the image, but will dissallow ALL disk writes?

Do I have to do this on a case basis...disable caching to pagefile, disable virtual memory(???)...disable any other processes that might write my App to the HD (are there any others?)

The only process I know of that writes an executable to the disk is caching to the pagefile. Are there others that routinely do this?

Any information would be greatly appreciated. References to relevant sources would be of use, too.Thanks much,

Les
