Windows update with services shut down

[Blackstickman]

Hello all,

I could not find this topic anywhere on these forums, so here's my question: I use Desktop Maestro from PCTools to clean my registry, clean out temp folders, etc. This program also allows you to "tune" Windows services. Now I read somewhere that Windows Update doesn't download all available updates if you do not have all the default services running. Is this true?

Thanks in advance.
