Windows 10: Update from Win 8.1 Pro to Win 10 pro - faliled Windows 10 installation has failed

Hello, I have problem with update operating system windows 8.1 Pro to Win 10 Pro on my laptop Asus G750JH. I used MediaCreationTool21H2.exe to update. I chose the option to upgrade windows. Installer downloaded the instalation media and updates and started installing. When the instalation process was about 50%, it displayed error message window: "Windows 10 installation has failed". Here are setup and error logs and setupdiagresults.xml:https://www.dropbox.com/s/wpis46abif0tn3w/win81_to_win10_setup_log.rar?dl=0I am IT developer and I develop software add-ons for Siemens industrial software

Win 10 1607 update

Installed the update manually at the the moment everything is bueno.
It seems that Microsoft has a big problem in there update department windows 7 update has problems win 8 update has problems. Windows 10 update is so-so.

 

Win 10 Pro upgrade using Win 8 Pro product key

I just bought a new computer running Win 10 Home. When I went to upgrade to Win 10 Pro using my Win 8 Pro product key from my old computer, the upgrade wouldn't activate.

Now I'm stuck with a bunch of error messages (mainly 0xC004C003) and am being told windows isn't activated. I can't seem to get my activated Win 10 Home back.

I don't have a product key for the Win 10 Home because it came pre-installed. There's no product code recorded on the packaging or labelling on the device.

So:

How do I either

• activate the Win Pro upgrade, or
• Get my activated Win 10 home back?

 

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?
