If you select the block adding Microsoft accounts option, users will not be able to create new Microsoft accounts on this computer, switch a local account to a Microsoft account, or connect a domain account to a Microsoft account. This is the preferred option if you need to limit the use of Microsoft accounts.
If you select the block adding and signing in with Microsoft accounts option, then in addition to the above, all existing Microsoft account users will not be able to sign in to Windows 8. This will also include any administrators that are using Microsoft accounts, so you might not want to do this option if this is the only administrator account on the computer.
