Using CreateProcess Instead of _tspawnl to Spawn Programs

If you use _tspawnl when spawning a new process, all the handles from the creating process are inherited by the created process. This can have undesirable side effects—especially if it's not what you intended.

For example, if the created process inherits an open file handle, the creating process may have problems manipulating that file. To avoid inheriting handles, use CreateProcess, and set the bInheritHandles parameter to FALSE.
