问题
There are questions about OS version on the Stack Overflow but not about the Windows name, I am looking to find out Windows name using Node.js.
I have looked into so many modules like os, platform, getos and using process etc. and found that these are helpful to get operating system description, process environment etc. I am able to get it is Linux or Windows too i.e. which platform I am using.
But, how can I check, is it Windows 7 or 8 which is installed on my system using Node.js?
I am using kinect2 module in my Node.js project which is working fine on Windows 8 but I am looking to use it on Windows 7.
I have checked that Kinect2 will not work with Windows 7.

You can find the Windows version from the command line using ver. For example, on my machine:
> ver
Microsoft Windows [Version 10.0.14393]
To execute this from node, use the child_process.execSync method:
var versionString = require('child_process').execSync('ver').toString().trim()
The whole .toString().trim() business is because the raw output from the command comes back as a Buffer, with newlines at the beginning and end.

Use os.release().
> os.release();
'10.0.18362'
On Windows, the result is in the form major.minor.build
Consult this table (source) to determine the version of Windows:
Version major.minor

var os = require('os');
console.log(os.type());
refer to this link for more references: https://millermedeiros.github.io/mdoc/examples/node_api/doc/os.html
The other alternative can be the npm library : "platform"
