Hardware Telemetry: Monitors CPU, GPU, motherboard, and hard disk temperatures and usage metrics via integrated plugins.

Visual Customization: Supports downloadable display skins and custom fonts to match your Windows desktop theme. Performance & Usability Review Pros:
Extremely low resource footprint. It uses negligible RAM and CPU cycles while sitting in the background.
Completely free, open-source, and clean. No embedded advertisements, trackware, or premium paywalls.
High customizability. Users love the ability to switch between taskbar view and floating view seamlessly. Cons:

Turning on the advanced hardware temperature tracking features relies on external libraries (like LibreHardwareMonitorLib.dll), which can occasionally cause stability issues or minor application crashes on specific Windows configurations. How to Install and Set It Up
