If you run Spybot (I don't run it any more since it went paid, so I've done everything manually) that will list all of the telemetry hosts. There are 115 in total, if I remember correctly.No it's fair - I've run Spy<bot anti-beacon for yonks. I just don't see why I should be feeding them all my info. At the minute I'm running NMap to see what traffic goes where and try to suss out what unwelcome and uninvited traffic I should block.
You can also monitor activity on open ports by using the netstat command, or better still, a freeware tool called CurrPorts from NirSoft. This little tool will also list the process that opened the port and let you close connections or save the connection info.
IMO this kind of thing is just plain abuse of its own customers by Microsoft. After all Windows is a paid for product - a portion of the cost of a new PC which has Widows pre-installed goes to pay for the Windows license. I know that Microsoft are not the only ones doing this in one form or another, but if I pay for a product then I do not expect it to be spying on me and selling on the information.
