I'm preparing a PC with a Windows 10 license and an installation USB. I want to upgrade but keep using the old one. Do I need to purchase a new license for Windows 10 or can I use the free version? I've seen some guides online that skip the product key during setup, but why? Some suggest it might affect customization or system compatibility if you don't provide the key.
You can download Windows 10 for free, though there are restrictions in several areas and a watermark appears in the corner. It remains functional as it preserves essential features. You cannot apply the same product key on multiple computers, but a non-OEM key can be shared between devices. There are limits on transfers before the feature is disabled. There are no barriers preventing full use of Windows 10 at no cost.
If you disable the key on your current PC, you should be able to use it on the new one. Each PC must have its own active key.
It all comes down to the type of license. If you purchased a retail license, it can usually be transferred, though I don’t have the exact details. For an OEM license, it’s tied to the specific motherboard and won’t move unless changed. If the transfer doesn’t work, there should be a Windows button that tries to recognize and apply the license. If that doesn’t succeed, reach out to Microsoft—it should fix it as long as it’s a retail license.
