Change Windows 8 from a Microsoft account to a Local account
If your Windows 8 PC causes issues when logging in with your Microsoft password and you would rather not have this feature, you can turn your account into a Local Account, which does not require a sign in. This can useful if you keep forgetting your Microsoft password and you being locked out of your account.
Sign in to Windows 8, and then navigate to PC Settings. You can do so via the Settings pane (WINKEY + C, Settings, Change PC Settings).
Then, navigate to Users. As you can see, there’s a handy button named “Switch to a Microsoft Account”.
Step 1: When you are on Windows 8 desktop, open the Charms Bar using the Windows+C hotkey and click on Change PC Settings to open the Metro style page PC Settings.
When you click this button, you’ll be asked to confirm the password for the local account. If you didn’t supply a password—shame on you—just tap Enter.
Now click the Disconnect option as shown below:-
Then, you’ll be prompted to enter the email address of your Microsoft account/Windows Live ID, and then the related password, and the security verification info.
Once this is done, the PC will update your account log in method and then in future you won’t have to use a password to log into your computer again.
