WOW Applications Stack Fault When Launched by a Service

CAUSE

WOW applications create a secure shared memory region during startup that allows only logged on users access. When a service launches a second WOW application, the resulting process will attempt to open the existing shared memory region. Because the security context of the process started by a service is not purely interactive, when it attempts to access the existing shared memory region, it gets an access denied error. The second WOW process will continually try to access the existing shared memory region until a stack fault occurs and it terminates.
