That's a false analogy, since Windows' services are rarely targeted for exploitation compared to say Internet Explorer, Adobe Acrobat, or Adobe Flash.
The customization argument holds some water, normally, but there's no real customization going on with services, so it really doesn't apply here either. Unless we're talking about you disliking the Aero UI and turning it off in favor of a more Windows 2000 style interface, we're not really talking about customization.
I'm not going to stop you if you're bent on doing this, but I am going to attempt to strip away the rationalizations you've used to convince yourself that it's a good thing. If, after all that, you still want to go ahead, knock yourself out. Just do so based on facts, not some perceived (but imaginary) benefit.
To paraphrase the late great George Carlin: We bought a Saab! Well what'd you buy a Swedish piece of crap like that for? It's a safe car! Some of these people think that by buying a safe car it excuses them the responsibility of having to learn how to DRIVE the bloody thing! First you learn to drive, THEN you buy your safe car!
So I'm not sure who you're trying to convince more right now, me or you. Just don't mistake my intentions like so many do. I'm just here to strip away all the nonsense and leave you with the raw naked facts. Then you can make a decision based on that raw information, and not some warm fuzzy feeling that won't really do much to protect you should the situation arise.
