Okay a friend of mine sent me a file in an email through Hotmail. I went to download it and a message came up about opening a window to play the message in, and unfortunately I noticed the "remember my preferences" box was ticked after I clicked okay.
It turned out that I couldn't play the file from that site, but now I don't think I can download any file straight to my hard drive from an email. How can I undo what I did, please help thanks.
