If you choose the second option, you can set up the PC using an account in your Windows Active Directory domain or you can sign in using an Azure Active Directory account, such as the one associated with an Office 365 Business or Enterprise subscription. On business editions (Pro, Pro for Workstations, Enterprise, and Education), the Windows Setup program asks you to choose whether you want to set the PC up for personal use or for use on a network managed by your organization, as shown below. Depending on your Windows edition and network setup, you have a choice of up to four separate account types. When you set up a Windows 10 PC for the first time, you're required to create a user account that will serve as the administrator for the device.
