Since I've been on Windows 7/my new computer, my mouse has changed appearance at random. I don't want it to, so when searching for answers the other day, I came across something you could download that would make it so the mouse wouldn't change. I downloaded it. Since I did, I am now unable to switch the pointer back to normal when it automatically changes. I cannot figure out how to undo this. I think the download may have changed the registry & I don't know how to undo it.
