I don't exactly know or remember, how this can be manually modified. But there's a third party toolkit which has an option to do this. It's called WinReducer EX-100.
The file you are trying to replace is located in "sources" directory of root, called "background_cli.bmp"
Hey, did you find a fix for this I am currently trying to do the exact same thing.
Edit: I actually manually replaced the background_cli.bmp in the sources directory however this did not seem to change it from the blue to a plain red colour that I had edited it to.
Thanks
I found the solution, after ~8 hours of trying.
The solution is as follows (also working with 20H2):
- Extract / Flash the Windows ISO File
- Temporary copy "boot.wim" to a place of choice
- Mount "boot.wim" with gimagex (Select the 2nd image - there are two images in boot.wim)
- Delete "boot.wim\sources\background.bmp" with Unlocker, then add your own with the same resolution (bmp, 24bit)
- Delete "boot.wim\Windows\System32\setup.bmp" with Unlocker, then add your own with the same resolution (bmp, 24bit)
- Copy "boot.wim\sources\spwizimg.dll" to somewhere temporary and replace the bmp source file (517 : 1033) with Rescource Hacker, then remove the original one with Unlocker and paste your modified one in the sources folder
- Now unmount the image with gimagex by checking the CheckBox "Commit Changes" and then press Unmount
- Copy the modified "boot.wim" back to the Flashed / Extracted Windows ISO File
Here is a tutorial I found with the exact steps: Customize Your Windows 10 Installation to Create the OS of Your Dreams - YouTube
Attention: Follow every step carefully!

It may even be better if you upload a good quality scan or picture of your stickers/labels so we have then flat to work with.

If that is the ONLY customisation that the OP wants to implement, this will do what they want . . .
