Am about to 'try' and change, would love a free version, but can you tell me if my Microsoft Office 2010 will work also will my Windows Live Mail work?? thanks for any help
Both Office 2010 (including Outlook) and Live Mail should work on Windows 10, but Live mail has been end of life for almost 4 years now and Office 2010 will go end of support in October 2020.
You may want to switch to a supported product (Office 365 or Office 2019 if you want to go paid) or you can choose from several free email clients such as the built-in email client for Windows 10, MailBird, or ThunderBird.
