Windows is activated without entering a license?

I installed a new hard drive in my laptop and installed Windows 10. I was not asked for a license or something similar. Asked. The status at activation says "Windows was activated with a digital license".

What does that mean? I have not entered a license.

Since I want to sell the laptop, I don't want the buyer to have problems with Windows.

Have you signed in with your Microsoft account? Your license is no longer tied to the device, but to the account.

Win 10 has saved the original key in the BIOS and read it out automatically during installation with the new FP.

Windows is now via. MSKMS registered online directly with Microsoft and the corresponding hardware is also stored there.

Hence, Microsoft knows that this laptop has already been activated with Windows once.

A potential buyer will have no problems.

In general, if windows is activated, windows already has a license for your hardware ID.

The BIOS no longer needs it. Is present at ms.

I didn't know, thank you very much!

That's right.

If you look in the activation it will say:

"Windows was activated with a digital license"

Means: Microsoft recognized your PC after the installation and automatically activated the installation. This works if only individual components are exchanged; not for major modifications, such as B. New motherboard / processor.

We would rather say the hardware ID is available. So the sum total of the individual components.

He wrote the digital license and it is tied to the device and does not have to be linked to a Microsoft account.

Write that to him as an answer, he is sure not to read it here as a comment.

Thanks… Didn't want to make it too complicated.
