windows - Microsoft products cannot connect via https -


we're having problem here few hours on google suggest common unresolved.

since upgrading windows 8.1, no microsoft product can connect site via secure channel, tls channels.

internet explorer 11 can connect http web sites (e.g. msn), not connect https web sites (e.g. login.live.com, google). attempting connect https site results in 'this page cannot displayed'. other browsers, example firefox , chrome, can connect https web sites well.

on own wouldn't issue, use firefox (which our default browser anyway), every single microsoft product uses same settings , transports internet explorer, , none of can connect secure sites either.

this means windows update won't work, , cannot register microsoft software (e.g. office, visual studio, etc). attempting results in 'a communication error has occurred.'

sometimes gives error code, example attempting activate office gives 'a communication error has occured. please verify have connectivity internet , try again (0x80072f8f).

googling code suggests checking bios date , time (we did, correct) , resetting internet settings (we did, no avail).

we had same problem crop on windows 7 after windows update, fixed going internet options , disabling tls 1.0 , re-registering dlls, hasn't fixed issue here.

other things we've tried are:-

disabling spdy/3

disabling ssl 2.0

every combination of enabled , disabled tls 1.0, 1.1 , 1.2

disabling enhanced protected mode

clearing ssl state

uninstalling internet explorer 11

as mentioned @ start, affects microsoft products, other companies or write ourselves works perfectly, suggest there's specific settings or code microsoft use root of issue.

anyone else had , managed solve it?
