As the title says: Update KB3176493 breaks Windows Live Mail (2012); it will not receive emails from a POP3 server, just gives a "Your POP3 server has not responded in 60 seconds ..." message, with error code 0x800CCC19.

Interestingly, I have a Windows 10 laptop, which did not get update KB3176493; it got KB3176495 (and I've no idea what the difference is - perhaps its for a different base version of Windows 10. No problem with Windows Live Mail on that machine after the update.
