Excel upgraded without permission

Copper Contributor

I have a new laptop and chose not to use the new 365 for my files and instead put my old Office 2010 onto it. Well last night the laptop did an update and all of a sudden my files have been converted to 365. I don't want this but cant open them in Office 10. How do I convert them back please?
