The patches also broke the Junk Email detection, many many posts on the MS community forums advising that no junk mail is being detected.

Three Microsoft Outlook patches unpatched, users left to DIY
Busted Windows 8, 10 update blamed for breaking Brits' DHCP

Not just BT
It's happened to my parents PC (using Sky Q Hub) and a friends (Virgin Media) both within 24 hours of each other.
Thought it was McAfee AV at first as they both use it (I know!) and after removing the software the computers were able to get an IP via DHCP and all is OK.
Wondering if removing the AV has reset something in the TCP stack?
Going to reintroduce software next week, see if it borks again.
