Windows 10: My windows is activated and has not a serial key as It is embedded with my Microsoft...

My windows is activated and has not a serial key as It is embedded with my Microsoft account so how can I reinstall windows without loosing my activation

:)

 

Acceptable activation serial key

Enterprise doesn't have to be VL activated and can be activated against Microsoft's own Activation servers. Currently my only option is to activate with my legal MAK keys which get a DL.





And as mentioned can be run as a 90 day trial.

 

Windows 10 key not activated

Hi

Thank you for your reply but I installed my Windows 10 trough USB and I chose the default option (keep files) the first one. But until now its not activated and I have a legit Windows 8.1 the serial key is embedded in the bios. Please help!!

I followed all the steps in the video and run the installer in the windows 8.1 not in usb boot up. While installing the Windows 10 it asked me for a serial key and it has no skip button just like in the video so I put this serial key TX9XD-98N7V-6WMQ6-BX7FG-H8Q99
as stated in the video description (link ) I dont know my key because its embedded to my bios and now my windows is still not activated
I felt disappointed .

 

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...
