Old windows key from laptop to new pc without activated windows?

I have windows 10 pro on my new pc but it is not activated can i read the windows key from an old laptop and uninstall it so that i can activate it on the new pc if so how?

You could delete Windows on your notebook. This means that the license key is automatically no longer in use. The key should be noted on the underside of your notebook. But I suspect that a home version is installed on your notebook and not a Pro. You would have to get a new key. They're not even expensive anymore

There's a tool with which you can read out the key

If it doesn't work then buy a Win 10 Pro Key for 12 euro on http://www.mmoga.de

Can I not downgrade the windows to home on my pc?

I also thought about it but I'm not sure about the lizengo things and such

So I've already bought over 10 win 10 licenses from mmoga and had no problems

Then do i just have to enter the mmoga key under change product code or whatever else windows is already installed

Yes on your new PC, press activate and insert the key and then you are done

OK thanks

Hä waitke with you is on a new PC product key change then idt windows yes activated?

But be careful that you buy the right key Pro or Home, otherwise it won't work

Everywhere it is displayed it is not activated but it says Change product key

Windows can't be activated on this device because you do not have a valid digital license or product key. If you think you have a valid license or key, select Troubleshoot "below. Error code 0x803FA067

Probably because the key is still in your account but recognizes that it is still installed on your old PC.

Do on your old pc

Look here https://www.giga.de/...so-geht-s/

Edition then stands for pro buy

Yes, but first look at the comment from just now

Assumed my laptop has pro then I would have to proceed as in the link on the laptop and then only enter the key on my new pc right?

The old pc with the license key can no longer be started so the key is probably gone

Yes then you have to buy a new one

Do I have to uninstall the non-activated key from my windows or is it enough if I simply go to Change product key on it

Worked without a hitch at mmoga thank you!

You must have the old one. You can't read it out.

BUT. You can look up the serial number and legally call Microsoft and ask for the code.

The hotline is super friendly, by the way.
