Windows Vista’s blinking cursor can be very thin that sometimes it can be very hard to clearly see it. This is especially true if you are using a laptop. But it’s really easy to make the cursor thicker—pretty much as thick as you want. Here’s the hack: select Control Panel→Ease of Access→Optimize visual display. Scroll toward the bottom of the screen, until you come to “Make things on the screen easier to see.” In the box next to “Set the thickness of the blinking cursor,” select a number. The larger the number, the fatter the cursor. You’ll see a preview of the cursor in the box next to the box. Click Save. The cursor throughout Windows Vista will now be fatter and easier to see.
