INFO: MTS and COM+ Processes Do Not Load the HKCU Registry Hive (202785)

SUMMARY

MTS and COM+ processes do not load the HKEY_CURRENT_USER (HKCU) registry hive that corresponds to their application identities. As a result, MTS and COM+ applications that have dependencies on HKCU do not work. Notably, this includes applications that perform messaging (which may require a user profile), applications that perform printing operations, and applications that require a client certificate.

MORE INFORMATION

Because the user hives are cached, if the registry hive has been previously loaded (for example, if the application identity is logged on to the computer interactively), the hive is available, and the MTS and COM+ applications can make use of the hive until the next reboot.
