After having done a quick search, it is supposedly impossible to revert back to Windows 7. Which leaves with the only option as to reinstall from
scratch the original Windows 7 version you received with your laptop when you purchased it.
There should be either a Windows 7 sticker somewhere on your laptop with the accompanying Serial number. This number should let you legitimally
install a fresh copy of your operating system, either by ways of system restore preconfigured by the fabricator of the laptop, or by inserting the
DVD-Rom provideded by your reseller/vendor.
There are a multitude of options which could apply. I suggest your contact the shop where you bought your laptop and ask your specific situation. They
can probably reinstall it for you, but I think that would cost you the same as the $80,= for the upgrade.
Ask your peers. Usually people know people who can assist you asses what you should do, or help you for a beer or 2..
