sharing variables accros processes & process starting
Yes. An NT service can launch new processes. By default they will run under
the same account (e.g., LocalSystem) that the service is running under. To run
under a different account it will need access to credentials for that account
(e.g., a token), and use an API such as CreateProcessAsUser.
There's a few different mechanisms to pass data to child processes:
memory-mapped files, environment variables, inherited object handles,
WM_COPYDATA, anonymous pipes. "Best" depends on a number of factors (speed,
security, ease of coding, ...).
