I have around 2K email as unread in hotmail. How can I mark all of then as read in one go?
It's rather easy. You just put a check mark on the box in top left side (just beside 'Show:') of email list. It selects all mails in the view. Then hotmail will provide you an option just above list of mails: "xx items selected. Select everything in your ???? folder". Just click 'Select Everything'. Click upon "Mark As > Read" on the topmost bar. The operation will be done in seconds.
