I'm sorry, it is Google Chrome and Windows 8.1. I think it worked some days ago. I have had some trouble with anti-virus programs; I couldn't complete installations of AVG and Norton, and Windows Defender didn't work either, but suddenly Windows Defender started working. Hotmail works on Internet Explorer. I also have some trouble with Facebook on Google Chrome, but it's fine on Internet Explorer. On Google Chrome I can't open chats in the bigger chat-window, only separately, and sometimes I can't get it to play videos.
