| Test | Expected Result | |------|-----------------| | Boot Media Loads | WinPE splash screen appears, then PassFab UI. | | Registry Tool Runs | No crash; the “Loading registry…” progress bar finishes. | | Password Reset | Account password changes successfully, no error messages. | | Secure Boot Enabled | System boots without disabling Secure Boot (thanks to the signed patched image). |
If any step fails, double‑check the file names, especially that boot.img is exactly the patched version and that ForceUEFI=1 is present in config.ini.
The good news: the underlying binaries are still functional; only a couple of files need to be swapped and a config tweak applied. That’s exactly what rontoolsie’s fix does.
