That's another thing, some services, on my machine at least, seem to interpret the manual setting as a stop command - Windows Installer being one of the culprits. Every time I need to use the installer it's necessary for me to start the service by hand and, as soon as it's done its job, it switches off (I have it on manual as it's not one of these services that you call on all the time). Still, that's just a minor gripe.
