Thank you for posting your query on Microsoft Q&A, from above description I could understand that you are looking for a way to login to your windows device with corporate (*.onmicrosoft.com) account.
Please do correct me if this is not the case by responding in the comments section.
- *.onmicrosoft.com is a corporate account and could never be turned into a Microsoft (personal account say live, outlook or hotmail.com).
- To login to a device using corporate account, you need to get the device Entra ID joined.
- For steps to manually join devices to Entra ID kindly follow Microsoft Entra join a new Windows device during the out of box experience
- You can bulk provision Microsoft Entra joined devices using the following approaches: Self-service in OOBE/Settings - In the self-service mode, users go through the Microsoft Entra join process either during Windows Out of Box Experience (OOBE) or from Windows Settings. For more information, see Join your work device to your organization's network. Windows Autopilot - Windows Autopilot enables preconfiguration of devices for a smoother Microsoft Entra join experience in OOBE. For more information, see the Overview of Windows Autopilot. Bulk enrollment - Bulk enrollment enables an administrator driven Microsoft Entra join by using a bulk provisioning tool to configure devices. For more information, see Bulk enrollment for Windows devices. Please "Accept the answer (Yes)" and "share your feedback ". This will help us and others in the community as well.
