Activated instantly, no problem so far.

Works great, thank you.
First there was some issues with activation, but technical support of this store helped me in just few minutes, so everything is good. Thank you for great customer service, not many shops care about customers as you do.

Worked just fine, as the info on the top of the screen suggests it should be used with the pro version of windows to avoid any complications.

Worked perfectly. No problems for now.

My license didn't work on the first try, but the customer service is very efficient, they answered my question within minutes and I was able to solve the problem. NOTICE: "Windows 10 PRO" licenses are not valid for "Windows 10 PRO N" (European version) you must install "Windows 10 PRO"
