After updating to windows 8.1 I am having a bit issue with surfing website. I am unable to visit flash based site. They are very slow and looks like sluggish. Whenever I try to play a few videos through youtube it takes a long time to start. I am stuck with the issue. Many website which already has a youtube video embeds in them does not load. Internet Explorer crash sometime and does not respond on any click. Is this a bug in Windows 8.1.
