Windows 10: 21H1 Unattended Installation Requires Enter Key Press

I'm not very experienced with unattended installations so I manage by doing self research. My unattended installation of 20H2 was working fine. I downloaded Windows 10 Professional 21H1 from VLSC and used the same files from the previous installation. The only thing that has changed is that the latest MS Office 2019 Pro Plus will also be installed during OS installation. During the last reboot, I simply get the Dell logo (as I'm testing out on a Dell PC) along with the circles spinning endlessly. If I force a reboot or press the enter key, the installation is finished and the desktop loads. I think it is perhaps the unattend.xml file that is causing this because removing it didn't cause a bootloop, although sysprep didn't complete which was expected. I've attached my fairly simple unattend.xml if anyone can help me understand this problem so that it can be resolved. Any leads?

Create media for automated unattended install of Windows 10  

The hard disk will be wiped empty if WillWipeDisk value is set to true (tutorial step 3.11).

About signature issue, I have not a a clue what you mean. If you follow this tutorial step by step, when you have finished capturing your customized install.wim, everything needed to create a bootable USB drive is in folder ISO_Files (or whatever folder you selected in step 2.2).

I use then my own PowerShell script to create bootable USB from ISO_Files folder as shown in this tutorial: PowerShell Scripting - Create USB Install Media for Windows 10 - Windows 10 Tutorials

If you want to make Windows Setup completely automatic, "hands-free", then yes, a generic key is required. If not given, setup will stop asking the key.

Generic keys are not activation keys, they are only used to skip product key prompt in Windows Setup, and in case of install media containing multiple editions, to select edition. Activation will then be based on existing digital license, or must be done using a product or volume licensing key.

 

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

mobo/case connection

Type LIST DISK

press Enter

(There are going to be several steps, so let me know when you do them, OK?)
