Windows Family on professional computer

Copper Contributor



Here are two old questions for me, for which I never found an answer. I work on a Surface Pro and Windows Family preinstalled on it. I have a Microsoft 365 Business Premium with Windows 10 Business supplied (if I understodd well) :


- is it possible to replace Windows Family by Windows business, and how ?

- on the computer, when i am asked to log to a Microsoft account, I never succeed in using a professionnel account (the professionnel Microsoft 365 account I use for everyday work). It says that it is not a Microsoft account and I have to use an Outlook account i especially created during the installation of the system. Is it the right way or is it possible to log with professionnel Microsoft 365 account ? 


Thank you

Windows family is not the name of a license. are you referring to Home?
Business editions include enterprise, pro workstation, education etc.

yes you can replace Windows and upgrade/downgrade editions

here there is full official details about these:

there is also no professional subscription for M365.

you can find all available ones here.

you need to sign into the Windows with the Microsoft account that contains your license, if not, you will have to buy Windows again.
