Windows 10: Serial number win 10

So basically my serial number it is not working at all why that?

:)

 

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...

 

Valid serial number not acceptd on Win 10 install

I downloaded Win 10 to a USB and tried to install it. When I was prompted for my serial number, it did not recognize the one I provided. It's the one reprortedby Belarc and also the one that came with the DVD that I used to install Win7 Pro on my computer.
With all of the activitiy going on with Win 10, I cannot find a way to reach someone at Microsoft to help resolve this. Any suggestions or different ways to try contacting MS would be appreciated.
