5U RETAIL Windows 10 PRO Professional License - DIGITAL Instant Activates - 5 Devices

Didn't work

Only worked for two devices, further activations were blocked.

My inital scepticism was totally unwarranted.

I was unsure about paying for a product that supplied 5 licenses for such an expensive product at a bargain price. However, my skepticism was unwarranted as I have installed two new installations of Windows 10 Pro and upgraded two Home to Pro versions using the 5 license key. I will return to this vendor for other product licenses as a totally satisfied customer.
