Hello & Welcome to JustAnswer. I'm Kamil and i will do my best to assist you.
Uninstalling Windows 8 is not a good idea since may run into other problems and may not be able to enjoy all the features of this laptop since it is designed for Windows 8
However, to most users what i have been recommending is to download software to get the Start Button in Windows 8 like Windows 7.
Which makes the Windows 8 much easier to use and adds a touch of Windows 7.
Would you like to try it out?
I am 76 years old and cant get on with windows8 at all. neither can my wife
Which computer are you using to talk to me?
my laptop HP
Is the Windows 8 computer still boxed/sealed?
it was sealed but i opened it up to test that it was working.It is but with win8 installed
And is it possible to return it for a refund?
yes at my expense. £30 + for recorded delivery
If you send it via RoyalMail then it would be £30 but if you use Interlink Express or DPD then it would be around £15. Since Windows 7 licenses are only for 1 PC you will not be able to use it on the Windows 8 computer. Buying a disc would cost you around £70 to £80 and since this computer is designed for Windows 8 i would not recommend running Windows 7 on this computer.
So the best option is to return it for a refund.
