I have an Alienware 15 R3 laptop (The newer edition) and it's been working fine since when I got it in early December. Yesterday, a box appeared in the lower-middle section of my screen and said something similar to "Windows Key disabled". And then the windows key stopped working. After trying probably 15 different unnecessarily complicated methods to re-enable it, I discovered that the windows key will work as long as I hold down FN. How can I change it back?
