system logo

Changing the BIOS/UEFI splash screen to include a custom logo (like the Windows logo + contact info) requires flashing or customizing your firmware, which is advanced and varies by manufacturer.

Replacing the Windows logo during boot or in system properties involves modifying system files or firmware, which is complex and risky.

To replace the Windows boot logo with your custom image, you'd need to modify the boot logo in the firmware or replace bootloader images—which is complex, risky, and varies by hardware. This involves flashing firmware or editing system files, which can brick your device if done incorrectly.
