System monitor is an app that I've developed on the Rainmeter backend for the Windows platform. It displays the utilization your system resources on your desktop in real time, but I primarily use it to troubleshoot my WiFi connections and running apps.
I created it for testing my homemade computer, but a few people have asked for it so I've decided to publish it for anyone to use.
1) Download System Monitor.
2) Extract the files.
3) Double click "Rainmeter-4.2.exe" to install it.
4) Open "System Monitor_1.0.1.rmskin" and allow it to install.
5) Run Rainmeter and enable the System Monitor skin.
Installation instructions are included if you get stuck.
Note: this will run on any Windows computer, but Windows 10 Fall update is required for the GPU monitor to work.
