Go back and ask for a refund,or installation of a legit copy. Tell them you will go to trading standards if it is not resolved to your satisfaction(Trading standards are pretty good at sorting things out)
If cash converters in the UK are anything like in Australia, they are not a good place to buy from and not even very cheap. I have seen 3 year old printers there for more then a new one.
As others say get a refund or get them to supply a legal OS.
if the laptop has a cd key on it you can phone windows and do a verification my os said this after doing a fresh install and once i had done this is was ok failing that trading standards if you cant get a refund
