Thanks everyone I do have a paid copy of M/S Office 2010 which I can (or should be able to) download from the email which is in Win7 on my desktop. The new notebook is the one with Win 10. However when I tried to download it on Win 10, it says it will take 9 hrs, and after a couple of goes of well over an hour, it still has only loaded 4% though other programs I've loaded up whizzed past much faster. Can you tell me why it would be so slow? I can't get in touch with M/S about it as I am in Australia, and wont ring the US.
Thanks re Thunderbird, I'll see what happens re MS Office 2010 first.
