On 7/29 I installed windows 10 free upgrade on Joe's Dell computer. During the upgrade I was asked something about Adamai, but I did not print the screen. I did 7 other Dell computers and this was the only one that made any mention of Akamai.
The upgrade installed Akamai 220.127.116.11/884d403. I did some research and discovered that the Akamai program helps large companies like Dell, distribute their web pages to the entire world. SURPRISE !! Joe's desktop is now a small web server that will upload the Dell web page to other nearby Akamai clients as needed, altruistically using a small amount of the boss's bandwidth to help the world.
Further investigation led me to believe that Akamai could be configured to be "Download only" which would prevent this small bandwidth loss. But, Akamai admintool and their control panel tool does not seem have any such setting.
Perhaps the windows 10 version does not have that functionality?
And yes, I am aware that it can be uninstalled, but I kind of like the idea of helping the world.
