You can change your cursor shape to a box or i-beam. Put the following in your emacs init file:
;; change cursor shape (setq cursor-type 'box) (setq cursor-type 'bar) (blink-cursor-mode 1)
;; highlight current line (global-hl-line-mode 1)
Note: on Windows, if you have Microsoft Speech Recognization on, or Screen Magnifier, then, cursor will be i-beam, and setting “cursor-type” has no effect.
