I just assembled a new PC, for the first time in years to replace a "dog" of a PC I use as a backup in case of failure of my main PC. All very easy these days and quite inexpensive.
I made a W10 installer USB from a Microsoft download. Worked a charm, and then yesterday the "activate your Windows" nagging started.
I had anticipated transplanting the license from the old PC, but then stumbled across an eBay seller with licenses for £2.68.
At that price nothing to lose in trying so I purchased one, and it works.
Can it really be legit at that price?
