Windows 10: Activate My Laptop's Windows 10 With My Laptops OEM Serial Code

Hello,

I had my laptop's windows 10 activated with my organization serial code but now I want to activate my laptop's windows with the OEM key.how can I do this? please help.

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...

 

Best laptop under $800??

Well the last one I suggested seems to be the best for 650$

Can't Activate Windows 10 on Windows 7 Dell Laptop

I installed Windows 10 while in Beta on an old Windows 7 Dell Inspiron M5040 Laptop. The original Windows 7 serial number is located on the bottom of the laptop but it came pre-installed. I made a backup but the installation files were of the installation
partition files but misplaced them over the last several years. on a separate partition. My Windows 7 was activated at the time I received the Laptop but I have never received a follow up offering me an upgrade to Windows 10. Instead, I was participating in
the Windows 10 Beta on this Windows 7 machine and also on a newer Dell Laptop that had Windows 8.1 installed (which was purchased this last December). The Windows 8.1 machine updated to Windows 10 and successfully completed the Activation process. However,
the older Windows 7 M5040 did not recognize the serial number indicated on the bottom of the case and gave me an error code 0xC004C003. I tried calling Microsoft but was told to call Dell who told me to call Microsoft. The other message I received was that
the Current Product Key was ***** - 8HVX7 yet this does not match the last five digits of the code on the bottom of my laptop.

Dells service site no longer warranties the laptop and has no records of the operating system that was installed on it when it was purchased. We kept doing a back and forth from Dell to Microsoft and back to Dell again with no help from either. There used
to be a verification process that could be done by phone. This is no longer available and the process for obtaining a Product Key is confusing.



Now I'm stuck. I have done a clean install of Windows 10 basically wiping out my C Drive to install the latest version from a USB drive. I can access Windows 10 but can not activate it. I have purchased Windows 7 Home Premium Upgrades for other machines
that I no longer use and I tried to use these serial numbers without luck.

What steps do I need to take to authorize the serial number listed on the bottom of my laptop so I can activate Windows 10????
