How to disable WMC related processes from starting automatically on every logon?

[Win10-Hater]

Hello all, on my Vista Ultimate SP2 x64 install, on every logon, the Windows Media Center Scheduler Service and Media Center Tray Applet processes start up. I don't want them to run on every startup but I am not finding a way to disable them from running automatically, even after disabling all Media Center related services in services.msc.
Any help would be greatly appreciated.
