The genuine, or validation, check is performed when your computer attempts to download optional updates from Microsoft. For example, when your computer downloads updates, Windows checks to see if your product key is valid. If it is, Windows on your computer is genuine, and you're eligible to receive the latest updates from Microsoft.

Windows 10 Serial Key Free Download
Active1 year, 3 months ago
I am trying to run the upgrade from my Windows 8.1 Pro computer to Windows 10. It keeps telling me:
Setup has failed to validate the product key
This has happened when clicking 'Upgrade' inside the Windows 10 Media Creation Tool and has also happened when running the installer from a flash drive. However, that flash drive did successfully install Windows 10 on another computer.
How can I fix this?
This computer is a Lenovo ThinkPad T530 which originally shipped with Windows 8 (basic), was upgraded to Windows 8 Pro, and then to Windows 8.1 Pro. When I run NirSoft's product key retrieval tool, it shows the original Windows 8 key stored by Lenovo in the BIOS as well as the Windows 8 Pro Upgrade key. Could it be that the upgrader has 'decided' that these keys are not eligible for upgrade?

I read through the log files in
C:$Windows.~BT
and discovered an error message that said:Unable to create temp file in C:UsersmeAppDataLocalTemp. The file already exists.
(That's not the exact wording, but it's pretty close. I'm typing this on my other machine while watching the installer run.)
I ran Disk Cleanup on the drive, which cleared out the Temp folder and the downloaded/unpacked installer files (in

None of the other answers worked for me, though Moshe Katz's answer did point me to the log files. Under
C:$Windows.~BTSourcesPanther
there are two log files, including an setuperr.log
which indicated to me that it was in fact a license key issue. This did cause me a little confusion because I was never prompted to enter a key; I suspect Setup was attempting to autoactivate using the Windows 7 key or was looking for a Windows 10 OEM license in the BIOS.I opened an admin command prompt, browsed to
C:ESD
where the media creation tool stores its files, and I ran setup /pkey xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
using the retail product key we purchased and Setup worked perfectly.ThomasThomas

Unlike earlier versions of Windows, you can’t install Windows 10 or 8 without a product key. Microsoft has made it compulsory to provide a product key before proceeding with the installation. But what if you want to install and trial Windows 8 before purchasing? Luckily there is a workaround to bypass the product key screen during Windows installation.

How to Install Windows 10 or 8 without Product Key?
- Follow this guide to download a official copy of Windows 10 / 8.1 directly from Microsoft’s servers.
- After you’ve downloaded the Windows 10 or 8 ISO image, burn it to a USB flash drive with the freeware ISO2Disc. It is easiest if you’ve created USB installation media, as you can later edit the files directly on your USB flash drive. If you created an ISO file, you’ll have to modify the files inside the ISO image before burning it to disc.
- Open your USB installation drive and navigate to the /sources folder. Look for the ei.cfg file and open it in a text editor such as Notepad. If the file doesn’t already exist, create a new text document and rename it as ei.cfg.
- Copy and paste the following text into the ei.cfg file and then save it. Make sure that anything that already exists in the file should be cleared first.
