My son upgraded to Win 10 and was very pleased with the result - all seemed ok. After about 24 hours he was unable to access secure (HTTPS) websites e.g facebook & twitter. Got a timeout and an SSL message.
Other sites seemed to work ok.
Tried rebooting, clearing DNS with ipconfig, switch off firewall, add facebook to firewall whitelist , reboot router etc. no joy.
Sites and accounts worked ok from another computer on the same network.
Youtube sometimes worked - sometimes timed out.
Suspect it was something to do with certificates but gave up after half an hour - too complicated.
Couldn't find anyone on google with the same problem on Win 10.
Gave up and now back on Win 7 (surprised how quick and easy this was).
May try again later.
