Just finally fixed the issue with IE11 crashing after watching youtube videos...
every time when I was streaming and watching the videos the IE 11 was chrashing but this TECH rep from microsoft was able to fix the problem with a couple of system configuration changes .. under Internet Options ,go to Advanced tab , first he checked SSL2.0
as it was unchecked by default and second he enable enhanced protection mode .. then hit okay to aplly changes and rebooted my computer after that we tried againd with youtube and VOILA' problem was solved no more crashing ..give it a try ......If it worked
for me it should work for you as well. KUDOS to that tech from Microsoft ....Iwish Iwould remember his name ...to give him a shout out.....peace
