And the vast majority of PC's that are bots or infected with malware are XP pc's for that very reason. So this is hardly a good reason to leave UAC off.
In terms of the OP's question, I found that disabling indexing was the one thing that helped boost Vista performance the most.
Only if you actually don't use the feature. A better method of fixing any performance loss caused by excessive indexing is to trim down indexing to the start menu and only the actual user files searched. Another thing you can do is trim down the types of files indexed to only those types you want fast searching for. Once this is done, indexing takes less than a minute for most people and rarely bothers you afterwards.
Once you learn to use the search function, to start programs and find files, you would be amazed at how much more productive you can be.
There's not much else you can do, unfortunately. I played around disabling services but it didn't really do anything.
That is because services run on a IO priority system and release resources to the actual programs you are running when needed.
One big thing the OP can do to free resources and speed Vista up is to turn off Defender's real time protection. Defender has a poor record of detecting malware, so it is not worth the penalty to have it on at all times. Use a good Anti-Virus package, like the Avira free edition instead. I hear Norton has their act together and is one of the lightest on the resources if you have the money to pay for it.
I would say that running Windows XP is pretty much the easiest and best way to run "Vista Lite".
XP is not Vista lite. XP is one big gaping security hole unless you run as a standard user. The problem with making XP secure is it is a lot harder to do than in Vista, which defaults to least privilege because of UAC.
