Akamai is, I think, something of microsoft's. So that would sound like telemetry, whether those other IP addresses are also for telemetry or something else I don't know.
I don't know enough to help you or advise you on finding what is doing the connecting, but if you find it I do have some advice for what to do next. If it is telemetry I wouldn't suggest deleting the executable, it might be an important part of your system. Better options would be those that can be reversed if they mess anything up, so for example in order of increasing desperation you could try: blocking it with your firewall, setting your router to refuse to make connections to those IP adresses, disabling startup tasks which cause those things to run, disabling scheduled tasks which cause them, disabling services that cause them, and if all else fails rename the executable used (this way windows won't be able to recognise it and tell it to run, but if you ever do need it you can rename it back to it's old name and have it working). Above all make sure to make a system image before trying any of these things, there are cases where methods as described there might help you get your system doing as you want it to do but they could also cause problems, incase they do make sure you can restore everything back to how it was before you did any of those things, Here's how: http://www.bleepingcomputer.com/tutorials/create-system-image-in-windows-7-8/
