Windows 10: Register a device with its serial number windows 10

I just can't figure out how to register my computer bought from my sister with my Microsoft account and to make sure that the Windows 10 license is transferred to me. Here's a video of my specific problem: https://share.getcloudapp.com/GGuodr1d


Thanks

Windows 10 serial on OEM


So I'll summarize steps made...

1. Saved serial number (taken with Belarc Advisory) from preinstalled (half chinese language) Windows 8.1 (don't know exactly the version, suspect Windows 8.1 with bing) on tablet
2. Formatted tablet
3. Tried to make a clean Windows 10 (HOME, HOME N and also PRO, everytime with the same result) install with ISO taken with MediaCreationTool, during install (and also after completing installation) it says that the saved serial is not valid
4. Tried to reinstall Windows 8.1 (ISO taken with MediaCreationTool again) HOME, it says that the serial is not valid

So i suspect that the saved serial, is from a WINDOWS 8.1 WITH BING OEM version and this kind of ISO is not accessible/downloadable anywhere (at least I can't find it, any suggestion?)

Still not tried SHOWKEY with that serial, I am in office now, and the serial is saved on a usb pen at home, will try this evening.

So I'm stucked but if everything is like I suspect, it's incredible. If I have a tablet/notebook/netbook with Windows 8 preinstalled, it seems that I can update to Windows 10 without problems, but if I want to make a clean Windows 10 install that serial is not valid...

 

Windows 7 define wrong serial number for USB device

I've plugged in the USB device (usb-ethernet adaptor TP Link UE300) and try to find out its serial number in device manager.

In device manager I've found according device, opened its properties, tab 'Details', there I found the 'Device Instance Path' property (as I know it keeps serial number). The value for the serial number is '000001000000' - it has nothing common with real
device serial number which is written on its body.

Could you, please, give me a hint, why the serial number detects incorrectly?

 

Serial number

The serial number should be on a sticker somewhere on the desktop.

You can also go into the BIOS to find the serial number.

This link has the info, it says laptop, but should be the same steps:
