I would warn you that disabling the Background Intelligent Transfer Service is not wise as more programs than you realize use it.
Also, RPC Locator is important.
More services than you realize are vital to the smooth running of the OS.
You may wish to review what programs can call upon what services before disabling them, as setting them to manual will not allow them to load, allowing the system to run faster, but also allows those services to be called upon and started when needed.
