Hi,
In this case, do I recommend doing a clean installation for Windows 10 rather than updating using the USB method?
If you have previously updated the key that is on the OEM computer, it will be activated in the Windows 10 version.
If it is a desktop you have made any hardware changes such as the motherboard, you will lose the attached license and you will have to purchase a new Windows license.
If you want to update you can use the media creation tools at the link below:

If you want to do a clean installation, I can instruct you using the USB method.
If it is a laptop or desktop, if possible, could you provide the laptop model or your desktop configuration?
Thanks
