Windows 10 download?

I bought a laptop without an operating system, but I would like Windows 10 now. That's why I bought a license, but now I don't know how to activate it on my device. Can someone help?

Did you buy Win 10 at home / a digital key? If you have it on a CD, just set it in the boot menu to boot from the CD.

You create a bootable USB stick with the Media Creation Tool. From there you boot your computer, install and activate it.

Oh, I've only just read that you already have a key.

Find a program with which you can copy a Win 10 ISO file from the official store, then insert the USB stick, boot from the stick and install it, and then you can activate your license.
