Why does my PC not have the "sign into a domain" option?

Question

I have a number of existing PCs that I need to bring under Azure management but the option to join a domain is missing from the Work or School account screen.

Hi Greg Hodge, I want to help you with this question This can have several causes

1. Your device is not connected to the Internet at this moment of checking (unlikely, but could be, otherwise check)
2. The devices have Windows 10 Home installed. Windows 10 does not support this feature
3. The devices used a build that is vulnerable, with problem 21H1 being such a case. Please briefly name the builds installed on the machines There are other ways to join the device. e.g. via the command line, with the following commands: DsRegCmd /join DsRegCmd /status Also, have a look here: https://www.maximerastello.com/manually-re-register-a-windows-10-or-windows-server-machine-in-hybrid-azure-ad-join/ For debugging errors, you can check below event logs: Event Viewer > Application and Services logs > Microsoft > Windows > User Device Registration > Admin I read in another thread that a workaround was to join a different workgroup, which made the option reappear afterward.
