I tried to sign up to receive email information from the program related to the Windows 10 upgrade and during the process I was informed that Microsoft wants to have access to my contacts list.

Now that is a very serious request, so there must be a fair bit of documentation about why Microsoft wants access to my contacts list -- where might that documentation be found?

What exactly will Microsoft do with my contacts list?

Who at Microsoft will be able to view the list?

And I will probably have more questions as those answers come in.

I did try to use the search tool here for answers, but without any luck, so if I made a mistake during that search, please forgive me.

Thank you to all that may be able to offer some help here.
