Hello Andy Kot,
Thank you for posting in Q&A forum.
You should ensure that the WindowsPE and Specialize passes do not fully automate the installation process, allowing the main installation window to appear.
For example:
<unattend xmlns="urn:schemas-microsoft-com:unattend">
<settings pass="windowsPE">
。。
<settings pass="specialize">。。
For more information, please see the reference:
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
