I have nothing but trouble with Windows Live Mail, since I got my new computer with 8.1

I had them install Windows Live and the messages are erroreous , the same message text appears in multiple email messages, and it is just a mess.

I want to un-install this product (not a good product by the way) and I am going with my service provider Frontier Communications. They use Yahoo as their mail service and so far it seems to work well--Frontier ports my email to my laptop and into Windows Live.

How much trouble will I have un-installing Windows Live and just using Frontier and Yahoo??
