Windows 10: windows 10 reload? Cannot locate Microsoft Serial Number.

I cannot access windows 10 Pro because the computer starts placing a string of dash's in the input bar. Tried the latest update and it is still the same. Go to the start menu and left click I get no listing of aps. If I ight click I can get to the next level of input until I have to choose with the left click and from there I am at a loss because I lose control. I think I found the Software's number but am not sure because this information has been upgraded many times.All I can see is a reload and rebuild, but how do I get a clean copy of windows 10 Pro?

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...

 

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:

Microsoft Selects Dolby Audio for Windows 10

it would've been great if microsoft added HEVC decoders, LAV filters along with other codecs with Windows 10, and developing WMP to be better than VLC, KMPlayer and such sorts of media players.

Nevertheless, this is good step for microsoft, by far.
