How to read the serial number of Windows 10

Hello World,
Like all Windows created to date even Windows 10 requires the inclusion of a genuine product key for it to function properly
In the event that the operating system has been upgraded from a version of Windows 7 or 8 via the free upgrade offered by Microsoft then there was the need to enter any serial key

Indeed, in this case Windows itself, once connected to the Internet by installing version 10 automatically recognizes the serial of previous Windows that you had installed on the machine and is automatically activated

But if I install Windows 10 starting completely from 0 then have to enter a serial number that can also be genuine Windows 7 or 8, you can of course also be found on the serial card purchase of the operating system

In any case it might be useful to show the serial Windows 10, maybe because I do not remember more or no longer have the activation card, can also be useful in the event that Windows 10 update to our old system and we want to find the key, so as to perform a new installation of 0

There are a number of applications that make our case to detect the serial Windows 10, but we visualize one in particular that is easy to use, very small and fast to use
The program in question is called Windows 10 Product Key Viewer

It is a small executable in terms of size, only 60 KB
There just simply download it and start it, some systems will prompt them to start as a system administrator
The program is portable, so you can take it on any system without the need for installation

Therefore just open the program you will see immediately the serial of Windows 10 and the version of Explorer installed (even that has a serial of his own)
By clicking on "System Info" we can immediately see the version of Windows installed on your machine and if it has been successfully launched
