If you no longer want to use a Microsoft Account to login to the computer, Windows 11 provides the option to switch your Microsoft Account to a Local Account.
In general, most users end up using a Microsoft Account to login to the computer right during the setup process, when they are prompted to use an existing Microsoft Account or create a New Microsoft Account.
When they follow these instructions, they end up being logged-in to Microsoft User Account, which Windows 11 automatically creates during the setup process.
Depending on your choice, you can either continue using the Microsoft Account or Convert the Microsoft Account to a Local User Account, which removes the Microsoft Account from your computer.
What Happens When You Switch from Microsoft Account to Local?
When you switch from Microsoft Account to Local User Account on a Windows 11 computer, the Microsoft Account will not be removed from the computer and the User Account will be converted to a Standard Local User Account.
All your Files, Photos and Data that were available in the Microsoft Account will be switched over to the New Local Account and you will be able to access them all.
However, if you had downloaded any Apps or Programs on the computer using Microsoft Account, they will still remain linked to your Microsoft Account.
Your Microsoft Account will remain active for all practical purposes and you will still be able sign-in to Microsoft Store, Skype, OneDrive, Microsoft Teams and other Microsoft services.
