What happens if I disable the Amazon EC2 Config Service on my windows instances? Is that service required? Are there performance benefits to disabling?

From the docs:

The EC2Config service sets up and initializes the instance during startup, prepares the service for bundling, and manages the event log.

The startup aspect is definitely necessary, and performance/memory hits should be extremely tiny. I wouldn't consider this to be a factor if you're tweaking your server for performance.
