Windows 10 has just updated.  I now find I cannot use Live Mail.  I tried to switch to 'Mail' but it won't accept one of my email accounts and only loads 37 out of a few hundred inbox emails on another account.  I do not want to lose these emails.  

I looked at the answers given on your support screens but the latest directly applying to my situation was August and it was incredibly complicated.

How do I obtain my 'live mail' without losing all the emails that were on there before the update, please?  I could try 'restore' but that may well not solve the problem and I will be going backwards with your updates

I am really fed up with windows 10.  Every time I switch on something else has changed.  It took me ages to work out I needed to download a different software to be able to see all my photos.  Why, every time there is an update users have to work out how to retain their computer's integrity?

I would heartily love to go back to Windows 7, but believe it will end up a total nightmare

Thank you

Lynden
