Using a Microsoft account does have some advantages over using a local account. For example, using a Microsoft account log-in lets you sync your settings across different Windows PCs. You can also use Microsoft’s integrated cloud storage, OneDrive. Downloading apps from the Microsoft App Store for the Modern interface (Start screen) requires a Microsoft account as well. But if you don’t use any of these features and would still prefer to switch to a local account, and you have not upgraded to Windows 10, here’s how:
Step 1: Go to Settings > Change PC Settings > Accounts > Your Account, then under your name and Microsoft account e-mail address, click on the “Disconnect” link.
Step 2: When prompted, enter your Microsoft account password to verify that it’s your account.
Step 3: Now enter the local username you want to use, your password, and a password hint.
Step 4: Click or tap on the “Sign out and finish” button to complete the switch to a local account.
