Where can I find the directory for Windows boot logo?

Fri Jan 15, 2016 10:59 pm

Hi folks,
I'm using build 10.0.10586 and interested in replacing the boot logo. Are these images in a directory somewhere I can swap? If so, anyone know where? My guess is they are compiled into one of the signed binaries. I appreciate any pointers you can provide.

If it was possible you would need to edit the file in c:\windows\boot\resources\bootres.dll then you would need to be able to edit resource 1 in that file with something like restorator it's a compressed archive of the boot logo images. Then you might need to be able to sign the file once repacked as everything seems to need signatures in iot.

That last bit is the difficult one.

You might have to do something like bcmedit /set testsigning on and then use signtool.exe sign bootres.dll.
