Microsoft restored the local account guide for Windows 11 possibly due to user demand and the need to provide support for those who prefer using a local account over a Microsoft account. The guide had been temporarily removed, but was later brought back along with some helpful advice for those wanting to use a local account on Windows 11.
Using a Microsoft account on Windows 11 provides benefits such as seamless integration of Microsoft services, enhanced security, syncing settings and files across devices, and easy access to Microsoft services like Outlook, OneDrive, Skype, and Xbox5. It also enables features like two-factor authentication and access to Microsoft's powerful security services, offering a more secure and flexible user experience.
A local account on Windows 11 is created on the device and doesn't require internet connectivity to sign in. It's independent of other services and not connected to the cloud. In contrast, a Microsoft account is associated with an email address and password and allows for seamless integration of Microsoft services, enhanced security, and sync across devices.
