You can help users activate Windows 10 devices in the following ways:

• Create or edit an activation email template to provide Windows 10 activation information. For more information, see Create an activation email template.
• Integrate UEM with Entra ID join: When Entra ID join is configured, users can activate their devices using only their Entra ID username and password.
• Configure Windows Autopilot: When you configure Windows Autopilot, the enrollment is part of the out-of-box setup experience and the device is automatically activated when the user completes it using only their Entra ID username and password.
