Again, I can't find any sources on its discontinuation.

edit

I still have Windows Contacts in Windows 10 and the old protocols still work, just because there are Metro-style apps that do the same thing doesn't mean that Microsoft has (already) discontinued these features, sure it may happen in the future but for now I can still find it on my computer (yeah original research but I haven't seen any source stating that Windows 10 removes it either). --Hoang the Hoangest (talk) 08:15, 6 August 2015 (UTC)Reply

I concur. I do see Contacts on my W10 computer as well. Billybobjoe321 (talk) 02:09, 12 January 2016 (UTC)Reply
