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.
