Windows 7 home premium Serial error

Hi All,

Please I need help, I have original windows 7 home premium 64 with serial , it was working fine for few years, but after system crash and re-installed the same copy it won't accept the serial again

I'm not an expert at this and i really don't know what to do

 

Windows 7 Home Premium OEM $90.00

Windows 7 Home Premium OEM $90.00 was $110 bucks!

This is the full version of Windows 7 Home Premium. It's key features include Jump Lists that keep the things you use most right in front of you as well as it's desktop enhancements that allow you to snap windows to both sides to easily view both at the same time.

 

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...
