## Description Monitoring CPU Temperature on Windows is challenging because most vendors don't publish this data to WMI. As a work-around, OSHI tries to use [LibreHardwareMonitor](https://github.com/LibreHardwareMonitor/LibreHardwareMonitor) via [jLibreHardwareMonitor](https://github.com/pandalxb/jLibreHardwareMonitor). If the temperature isn't found in WMI and jLibreHardwareMonitor isn't present, OSHI issues warnings every time `getCpuTemperature()` is called. This clogs the console with useless information when running on Windows and makes testing difficult. We could include jLibreHardwareMonitor as a dependency for our Windows jar, but LibreHardwareMonitor installs Winring0.sys, which is a kernel level driver with an unfixed severe vulnerability. Windows defender flags Winring0 as a vulnuratble driver and blocks it from installing. Rather than messing with it, this PR prevents Windows systems from calling the `getCpuTemperature()` method in OSHI.

Building
Gradle is used for all C++ and Java code, and pnpm is used for the web UI. Instructions to compile PhotonVision yourself can be found in our docs.
You can run one of the many built in examples straight from the command line, too! They contain a fully featured robot project, and some include simulation support. The projects can be found inside the photonlib-java-examples and photonlib-cpp-examples subdirectories, respectively. Instructions for running these examples directly from the repo are found in the docs.
