COleObjectFactory::UpdateRegistryAll() and Windows Vista

[Andrew Hain]

Our MFC applications have boilerplate initialisation code of the form:

// Parse the command line to see if launched as OLE server
if (RunEmbedded() || RunAutomated())
{
	// Register all OLE server (factories) as running.  This enables the
	//  OLE libraries to create objects from other applications.
	COleTemplateServer::RegisterAll();
}
else
{
	// When a server application is launched stand-alone, it is a good idea
	//  to update the system registry in case it has been damaged.
	COleObjectFactory::UpdateRegistryAll();
}

When this code is run on Windows XP, the program tries to register its COM interfaces. If the user is running unprivileged, it fails silently; this doesn't normally matter because the registry is set up when the programs are installed. However, I understand that Windows Vista throws up warning dialogs when programs attempt administrative actions, and wish to avoid that. Should we therefore get rid of this code?
