I am on a HCI program and I am now working on Chrome extension. I wonder if there is way Chrome extensions can fetch local operating system's version number.

I am now trying to read system's update logging so that I might extract the version number using REGEX. Yet it now seems that there is no way I can get access to files in OS due to security concerns and Chrome permission.

Can anyone give some tips or tell us this is completely impossible? Thanks guys!

*************************update 4/6/2018*******************************

To be clear, my goal is to see if OS has been updated to its newest version so that I am be able to remind users of safety updates. Thus I need very detailed info such as version number(e.g. Windows 10, 1709), patch number, build number(e.g. OS Build 16299.125), etc. Thanks!

There are several properties in the navigator. Maybe they provide you the needed information.

console.log("navigator.appVersion:", navigator.appVersion);
console.log("navigator.userAgent:", navigator.userAgent);
console.log("navigator.platform:", navigator.platform);

console.log("navigator:", navigator);
