An Akamai program installed by Dell to help download some files; it can usually be removed through the control panel, 'Add/Remove Software.' It appears to like to run though not really needed for anything.
This came from Dell's driver update tool that scans for current drivers.
It is a P2P software that constantly uploads and downloads content for various companies. No disclamers or installers refer to it in its installation, the website is really sketchy about its uses and functions, and it installed on a day my computer was offline.

Seems to be part of 'Need for Speed World'
It installs cloaked in order to prevent the user from removing it and then it starts sharing files to other users from your computer. It's simply a threat which hides in plain sight, being one of the most dangerous because of this.
A massively multiplayer online game (also called MMO and MMOG) is a multiplayer video game which is capable of supporting large numbers of players. If you install software to play free online, then netsession_win.exe might be installed with the package. Like Lord of the Rings online or dungeons and dragons online those type of games free to play online, and or Akamai NetSession Client, happy cloud, etc.
