Fetch OS level information through website

Question

I need to get certain OS-level information. I cannot install anything on client's machines, I only have option to open a URL in the browser on client's machines. I need to get following information if possible.

get OS version
Have they run Windows Update
Any Pending reboots waiting (from software installs) it causes issues with SentryBay install
Audio settings
- The name of the default recording and playback devices
- Whether either of those devices are muted
- Whether either of those devices’ volume is at 0
CPU
RAM
Should be running Defender only (for PCs)
Are they using wifi
What is running on PC (if their CPU usage is high they may need to close down or uninstall software)
Safe Mode needs to be off

The website can be coded in any language JS, PHP, Python etc.

Thanks.

This is generally not possible, the exception being if you want to require Internet Explore. Using IE, you could write an ActiveX plugin that could report this information. — TheGentleman, Aug 14 '20 at 15:59
To give up that information would be a VERY bad idea. As others have already mentioned some, very limited, information may be obtained but you aren't going to get most of what you want. — Dave, Aug 14 '20 at 18:14
Thanks for the comments. I already knew that most of the items are not possible but still i just wanted to explore more ideas. This has been very helpful. Thanks. — Kevin, Aug 19 '20 at 10:18

Most of this is not possible due to security concerns, however some browsers have implemented web APIs that can access some of this information. What Web Can Do Today has some great information about what sorts of device specific data can be accessed using APIs that were mostly designed for Progressive Web Applications.

Update: There is information on how to access the OS version in JavaScript here

Well, You can actually get the OS information of a device with PHP. It can tell if the user is using, Windows 7 or Windows 8 or Windows 10 or Android or Mac OS or IOS or more with this code:

<?php

$user_agent = $_SERVER['HTTP_USER_AGENT'];

function getOS() { 

    global $user_agent;

    $os_platform  = "Unknown OS Platform";

    $os_array     = array(
                          '/windows nt 10/i'      =>  'Windows 10',
                          '/windows nt 6.3/i'     =>  'Windows 8.1',
                          '/windows nt 6.2/i'     =>  'Windows 8',
                          '/windows nt 6.1/i'     =>  'Windows 7',
                          '/windows nt 6.0/i'     =>  'Windows Vista',
                          '/windows nt 5.2/i'     =>  'Windows Server 2003/XP x64',
                          '/windows nt 5.1/i'     =>  'Windows XP',
                          '/windows xp/i'         =>  'Windows XP',
                          '/windows nt 5.0/i'     =>  'Windows 2000',
                          '/windows me/i'         =>  'Windows ME',
                          '/win98/i'              =>  'Windows 98',
                          '/win95/i'              =>  'Windows 95',
                          '/win16/i'              =>  'Windows 3.11',
                          '/macintosh|mac os x/i' =>  'Mac OS X',
                          '/mac_powerpc/i'        =>  'Mac OS 9',
                          '/linux/i'              =>  'Linux',
                          '/ubuntu/i'             =>  'Ubuntu',
                          '/iphone/i'             =>  'iPhone',
                          '/ipod/i'               =>  'iPod',
                          '/ipad/i'               =>  'iPad',
                          '/android/i'            =>  'Android',
                          '/blackberry/i'         =>  'BlackBerry',
                          '/webos/i'              =>  'Mobile'
                    );

    foreach ($os_array as $regex => $value)
        if (preg_match($regex, $user_agent))
            $os_platform = $value;

    return $os_platform;
}

$user_os        = getOS();

$device_details = "<strong>Operating System: </strong>".$user_os."";

print_r($device_details);

?>
