You can go for Mac or different variant of linux,
Start with other OS from beginning is a good choice, But if you are using windows then you may face adaptation problem.
Its like you are left-handed trying to use right hand vice versa.
Still you may not find some good application for other OS that are available for windows.
but you could find most of them works pretty well.
If you ask me, who care about Microsoft if they make/change there OS, You could use a local account(without Email) or disable their Updates & security features ( must install another antivirus).
That is upto you to decide, Still just create an Email account with Microsoft so that you could access most of there features and apps.
Hope it helps
