Something that has not been discussed, yet, it's security. I have the opinion that a Service wich will not be used, doesn't have to be there in the first place. Yzöwl - before deleting/disabling a service, you know if you are gonna need it or not, therefor, it will never 'hurt' performance in the long run. As for security, I think we all share the same opinion. I'm not even gonna start with the 'Default VS nLited' war, I'm just gonna say that, if a service is exploitable (wich allot of them have been), the risk of been hacked is *allot* less (~ 0) on the computer in question than the ones that have it running. This is so obvious that we dont even any discussion. The same goes to everything else ... There is a exploit found on X, you dont have X, you wont be vunerable. As for the Thread Starter question, it all comes down to this: If you know exactly what you are doing (What services do, if you need them, etc), then removing and disabling will do the same. However, if you don't need them, removing would be a 'cleaner' job.
