WinPE Setup's backgrounds can be customized using a tool like Resource Hacker. Following NTLite forum policy, we don't discuss how to use those tools here, but there is plenty of outside discussion on this same topic.
If you want to copy modified files to boot.wim, it's possible when NTLite has loaded the image.
1. Download and install
PowerRun. This tool allows you to open a CMD shell with TrustedInstaller rights, and replace write-protected files.
2. Load
boot.wim (Windows Setup).
3. Open a CMD window, using PowerRun. Replace the
NLTmpMnt path with your temp folder's name.
Code:
cd C:\Users\GARLIN\AppData\Local\Temp\NLTmpMnt\sources
copy E:\modded\file.bmp background.bmp
copy E:\modded\spwizimg.dll spwizimg.dll
4. Close any CMD or File Explorer windows, you have opened to the NLTmpMnt folder.
5. From NTLite's
Image page, select the boot.wim image and right-menu "
Unload". When asked for confirmation, check "
Save existing changes to the image".
6. Apply other changes and create your ISO. Further modding help will be unavailable for this topic.
