Emulating the registry and running an executable to use that registry

Question

I am currently writing a program that takes other programs, copies them, and stores them in a different folder. The point of my program is to be able to run other programs with different settings. For programs that use config files, this works perfectly. However, for some of the programs, the config values they hold are kept in the registry.

I was wondering two different things:

1) Is it possible to create a "fake" registry

2) Would I be able to run an executable inside a sandbox to use the fake registry?

Thanks!

Answer 1

Using VirtualRegistry to Redirect Registry Keys on Windows Vista

Registry Virtualization

I have not used this before, but it sure looks promising.
