You know when the BIOS has handed over control to windows boot loader and you get the fancy circle spinning around as windows loads and there is always a fancy logo normally matching your motherboard manufactuarer. How does windows retrieve this logo from the motherboard.

Might sound like a silly question but just wondering

From my knowledge, windows haven't gotten full control yet when the mobo logo shows up?

“Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. Be curious. And however difficult life may seem, there is always something you can do and succeed at. 
It matters that you don't just give up.”

You mean, on POST? That's just the bios Splash Screen. Manufacturers like HP, Acer, Dell, etc... Put their own crap on there. Otherwise you'd get one from Asus, Gigabyte, MSI, etc...
You can disable it in the bios to show the conventional POST screen, where it shows what's the hardware of the computer is and where it's at in the boot process.

After that's done, you will be seeing Windows' logo during while Windows is booting.

Motherboards can replace that logo with their own during windows boot, however. It needs to be a UEFI install IIRC

The custom logo is stored in the Boot Graphics Resource Table (BGRT), which is only supported on UEFI based mainboards. Windows likely handles the throbber and status text.
