If you purchased any laptop besides a dell or a Chinese brand laptop you should be "semi-fine".
Just 5 days ago I chipped in half with my sis to get the
ASUS Zenbook UX305FA, it's works great and a big plus is that its super thin/light weight but the Window 8 is indeed a pain in the arse and will take a while to get used it.
You should of consulted with a computer expert(friend) before you got one :/
