Win11 Creator

📝 Provide a clear and concise description of the issue.

I’m seeing a reproducible issue with Win11 Creator output ISOs: unattended actions are not applied during setup, and first-logon actions never run.

🔄 Steps to reproduce the issue.

Repro

1. Use Winutil Win11 Creator to generate a modified Windows 11 ISO (latest iso downloaded the same day from Microsoft).
2. Boot from that ISO and do a clean install.
3. Complete OOBE and sign in to first desktop.

Expected

autounattend.xml is honored during setup.
FirstLogon.ps1 runs on first logon.
Post-install cleanup/actions happen (ex: Start bar cleanup, Windows.old cleanup, re-enable updates).

Actual

First-logon script does not run.
Other unattended post-install actions are missing.
FirstLogon.log is not created.

Additional observations

After installation is complete, C:\Windows\Setup\ only contains a single directory State. No Scripts folder/no scripts have been extracted here.

The generated/modified iso does indeed contain the autounattend.xml file on the root.

❌ Paste the full error output (if available).
