Usually, Microsoft charges $200 for a Windows 10 Pro product key, but you may be able to get it much cheaper than that due to a workaround. But Microsoft also still accepts product keys for Windows 7 Professional and Windows 8.1 Pro in its place. Those you can either find on one of your older PCs and use them for a free upgrade or purchase them for just around $5 on sites like eBay.

Such cheap product keys often work just fine to upgrade Windows 10 Home to Pro, though it’s worth noting that you should verify they’re obtained legitimately. Microsoft can revoke stolen keys, so there’s always a risk when using unknown sellers.
