Clean install, Remove previous Azure AD found during install

Question

We've received computers from a company that we took over. Those computers were managed by a 3rd company that owned the one we took over. I'm doing a CLEAN install of Windows 10 21H1 Pro on the computers. After the install, it NEVER offers to "Setup for personal use" or "Setup for an organization." Instead, it INSISTS on a network connection. Once it has a network connection, it goes and gets its Azure AD information and incorporates that. It then wants me to login to THAT Azure AD. I need to connect it to our Azure AD.

I've tried going into the BIOS and clearing the TPM and Secure Boot keys. This hasn't helped. I had Windows Setup delete ALL partitions on the hard drive before doing the clean install. This hasn't helped. I also used diskpart from the setup's repair option and did a Clean on the drive, no luck.

Ideas?

Answer 1

Marilee,

Thanks for the reply, but you're missing some of what I said.

1) A clean install has been done already.
2) It won't give me ANY option to login, other than connect to the other AAD.
3) I've done this before while disconnected from the network and make a local account, but even installing while disconnected from the network, the Windows 10 PRO install will NOT allow me to make a local account. It INSISTS on a network connection and then it grabs the other AAD as soon as it connects to Microsoft.
4) I have NO WAY to login under the old AAD. It's a different company. Also, it IS Windows PRO, so I should be able to create a LOCAL account, as long as I never let it connect to the network. As stated, I've worked through this problem this way in the past. However, THIS install will NOT give me the option to create a Local account, even if I NEVER give it a network connection. WHY?

This is a brand new USB stick created with the Windows 10 Media Creation Tool. The hard drive has been wiped. This is a CLEAN install.

Answer 2

No one? Why does a CLEAN install of Windows 10 PRO not allow for the creation of a local account when installing while NOT connected to a network? If I can create the local account, I can then take care of the rest of the problem.
