If you laptop came with Windows 10 installed, then the Windows 10 Product Key is embedded in the BIOS and is recognized automatically when you install or re-install Windows 10.
If you want to view/save you current Windows Product Key, you can use a free utility from NirSoft called ProduKey
ProduKey v1.93 - View or Recover lost Windows product key (CD-Key) and Office 2003/2007 product key

The product key that is stored in a motherboards BIOS (which they do since Windows 8 in 2012) is attached to the laptops serial number, so it wouldn't be of any use for any other device, which makes reading it out a nonsensical task.
Oh, by the way, there's also a specific German forum.
