Re-make laptop (Win10) as if it was new how does it work?

Sorry, wrong question caught.

Either reinstall Win10,
or about the Win10 recovery.

Go to Win10 Recovery: Go to Settings> Update and Security> Recovery> Reset this PC: Let's go> Choose from the two options "Remove All".
Please refer

Thank you, do I need the Windows Key? Do not have that anymore

It is even better if you reinstalled Windows 10 clean. This requires the Media Creation Tool: https://www.pcwelt.de/...68566.html

So you can create a Windows 10 USB bootstick. When you have created the stick, stick the stick, restart laptop and immediately press F2. Now you are in UEFI. There in the boot order put the stick in the first place. Save and exit. The laptop restarts and now boots the stick. Just follow the instructions of the installer. It offers the possibility to completely delete the hard disk. You do not have to enter the product key, it is permanently integrated in the UEFI.

When the installation is complete, just log in with the Microsoft account. Windows 10 will be reactivated.

Finally, you go to the manufacturer side of the laptop. There download and install the drivers.

Now you have a clean new set up system.

Quite complicated. : /

What do you need the key for?

Oh wait… Ne you do not need the key. I've misread the question, sry.

No, the product key no longer needs to be entered.

Since the product key was saved in the UEFI / BIOS during the first Win10 installation, it also does not need to be entered during a Win10 installation.
The activation takes place automatically, at the latest with the first Win-Update.
