Some idiot at Microsoft decided it would be a good idea to make the cursor look like it is always highlighting something. Since I spend most of my waking hours in a code editor, this has been driving me crazy. Finally, I'd had enough of it and went hunting around for a way to change it. Here's how to do it:
Go to: Control Panel -> Ease of Access Center -> Make the computer easier to see
Change the setting for "Set the thickness of the blinking cursor" to 1.
Save.
