There are two types of Windows licenses...

• Retail
• OEM

Retail licenses of Windows can be legally transferred between hardware because it's a retail license. Upgrade licenses if it was an upgrade from a retail license maintains the same license freedoms that the original license held, Windows 10 upgrade licenses are the only exception to that rule. OEM licenses however cannot be transferred from hardware to hardware. Upgrades from OEM licenses of course have the same restrictions that the original OEM license had.

However, right now Microsoft is still accepting old licenses of Windows as an upgrade to Windows 10. All you have to do is type in your old key and it will accept it. Why Microsoft is still allowing this I have no idea but my thoughts are is that Windows 10 adoption numbers are so damn low that they need all the help they can get. *Laugh :laugh:

 

Windows License Key

Windows 10 Digital License

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft
Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate. You will prompted to enter a product key a couple times through the installation, click I don't have
a key and Do this later.

There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key you already own to
reactivate if necessary. or use the reset function in Windows 10.

SCCM: In Place upgrade Win 7to win 10 1903 License issue

I was working on one task sequence for In Place Upgrade. Win 10 1709 to Win 10 1903 is working fine.

But Win 7 to Win 10 1903 is getting failed during Upgrade Operating System step.

I checked some of the links and added the KMS Client Keys (NPPR9-FWDCX-D2C8J-H872K-2YT43) in upgrade operating system step.

Also added one step to run vbs script.

But Task Sequence is getting failed at this step.

Command line Cscript.exe c:\windows\system32\slmgr.vbs /ipk NPPR9-FWDCX-D2C8J-H872K-2YT43 returned 3221549136

In my environment, we are using KMS and we don't have a Volume license.

Any advise how to resolve this issue.
