Hard disk change - how do I transfer Windows 10?

I have just received my "new" (used, but like new) laptop. On it a valid, clean version of Windows 10 is installed. I would now like to build a new, larger hard drive. It just fits a hard drive in, so I'll have to upgrade the old one and put Windows back on top of it.

But now the question about the license key - I do not have the key itself, since Windows was already installed and activated! How can I transfer the license to the new hard drive? Is this even possible, or do I have to buy a new Windows 10 version because of the change?

The seller said to me, the key is stored in the BIOS. Does this mean that Windows will be automatically activated during a new installation? Or do I have to open the BIOS and read the key somewhere and enter?

I'm just a little bit scared that it will not work and I'm forced to buy windows again.

PS: I realize how to install Windows over USB - it has been necessary a few times, so please do not explain again.

That's one possible variant.

Does this mean that Windows will be automatically activated during a new installation?

Yes, unless you replace essential parts of the hardware - but a different hard drive / SSD is not among them.

You can therefore reinstall Windows 10 as often as you like, the "Digital License" (as is a hardware ID) is stored on the Microsoft Activation Server, exactly your computer can be identified by this Hardware ID = Digital License and Win 10 will be automatic activated again.

I'm just a little bit scared that it will not work and I'm forced to buy windows again.

Even if it were, an OEM product key will not cost you 20 euro - and you do not have to worry about that.

Tip: You can "clone" Windows 10 to the new disk 1: 1, which makes sense if the previous system is clean and error-free.

OK thank you! I'll just try reinstalling. Cloning is unfavorable for me, because a) is on this anyway almost nothing on it and b) I have no housing or empty external disk to transfer.

Do you happen to know what Office is like? Is the key for my account, so synonymous on a second device? I bought a cheap key from Amazon, it works on the PC.

Depends on which office. Only Office 365 Home lets you share Office with multiple users on multiple devices at one time, and all other Office keys are only valid for 1 device and 1 user. Of course, you can uninstall Office from a device and reinstall it on one, if necessary, then you have to activate by phone.
