Hey Huys, I developed and simply application that just change a key in the
HKLM/System . Its a correction of a software we use here. We put it to run in
the login of all users, but the users that do not have adminstrator
privileges, the software cannot change the key in the registry. I would like
to know if is there a way of run my application as another user... but
automatically...not using "run as.." option, machine by machine...

Thanks..

Do all the machines have the same password for an account with
administrative privileges?

If so, on XP, you can use the sequence

LogonUser();
ImpersonateLoggedOnUser();

// do what you gotta do here

RevertToSelf();

to make the changes in the context of the more privileged account.

Prior to XP, the function LogonUser() required the SE_TCB_NAME privilege
which is typically granted only to administrators so it is not an option
there. You can use SSPI to accomplish the same thing albeit with quite a lot
more work. The technique is described here:
