As you know, there are various methods for logging on to a PC running Windows 8. If you had opted for logging on using Microsoft Account (Windows Live ID) during the installation of Windows 8 or changed to Microsoft Account (Windows Live ID) log on later, but have now decided that you want to switch back to logging on using Local account, here is how its done.
Open Control panel by clicking on the Control Panel app on the Start screen, click on ‘More settings’ > User Accounts. Click on ‘Change to a local account’
Enter the required information required to logon using a local account from now on.
Now you are ready to change to local account. You will therefore be now logged off, so save any unsaved work if any and then click on Log off and finish.
After logging off, for the log on, you will now be provided with a local account log on.
You should know that using Microsoft Account log on has some cool features as it syncs some settings across PCs you use. It also syncs settings like browser favorites, history, shortcuts, passwords for the various services you use.
