A modern, glowing system monitor skin for Rainmeter on Windows 11.

CPU · GPU · temperature · power · RAM · network · weather, all in one clean, theme-aware panel.

Preview

Coreglow skin on the Windows 11 desktop    Coreglow2 skin

Left: Coreglow1 · Right: Coreglow2

Two skins

Skin Load Style
Coreglow1 Coreglow1\Coreglow1.ini The original: compact rings, glowing bars, divider lines
Coreglow2 Coreglow2\Coreglow2.ini Large-type card layout with the same data and size (320 × 691). Larger, higher-contrast text for comfortable reading on Full HD, round-capped rings, big clock

Each skin is its own folder with its own @Resources (variables, accent preset, theme files, collapse state), so you can install, load and customize either one, or both, independently.

Features
🔥 CPU Usage ring, max temperature ring (green → amber → red), package power (W), clock (MHz), CPU name
🧵 Per-thread load One bar per logical processor. Adapts to any CPU automatically and turns color with load
🎮 GPU Usage ring and dedicated VRAM in use, read from Windows counters with no extra software
🧠 Memory RAM and swap/commit bars with used / total
💾 Storage C: drive usage plus live read/write speed and R/W activity bars

Requirements

Software Purpose
Rainmeter 4.5.6+ Runs the skin
Core Temp CPU temperature, power, clock and name. Must be running
Core Temp Rainmeter plugin (CoreTemp.dll) Lets Rainmeter read Core Temp. Find it on the Core Temp site under Add-ons

Everything else (UsageMonitor, PingPlugin, WebParser) comes with Rainmeter.

Installation

Option 1: installer (recommended)

  1. Download Coreglow1_x.y.rmskin and/or Coreglow2_x.y.rmskin from the Releases page.
  2. Double-click it, then click Install. Each installer only touches its own skin folder.

Option 2: manual

  1. Copy Coreglow-backup/Coreglow1 and/or Coreglow-backup/Coreglow2 to %USERPROFILE%\Documents\Rainmeter\Skins\.
  2. Rainmeter tray icon → Refresh all → Manage → Coreglow1 → Coreglow1.ini (or Coreglow2 → Coreglow2.ini) → Load.

See INSTALL.md for details and troubleshooting.

Customization

Right-click the skin → Edit variables, or edit that skin's @Resources/Variables.inc:

ini
PW=320                     ; skin width in pixels (bars scale with it)
Accent1=0,200,255,255      ; gradient start (cyan)
Accent2=150,90,255,255     ; gradient end (violet)
TempWarn=60                ; °C → amber
TempHot=80                 ; °C → red
WeatherLoc=                ; empty = Windows Location Service, or a place name (Athens)
WeatherUnits=m             ; m = metric, u = imperial (°F, mph), ms = metric with wind in m/s

Light and dark colors live in @Resources/Theme1.inc and Theme0.inc. Coreglow2 adds its own overrides in @Resources/Coreglow2/.

Note: Coreglow1.ini and Coreglow2.ini are saved as UTF-16 LE so that the symbols render. Keep that encoding when you edit them.

Building the installer

powershell
.\tools\sync.ps1                                        # copy both live skins from Documents\Rainmeter\Skins into the repo
.\tools\build-rmskin.ps1 -Skin Coreglow1 -Version 1.9.1   # → dist\Coreglow1_1.9.1.rmskin
.\tools\build-rmskin.ps1 -Skin Coreglow2 -Version 1.1.1   # → dist\Coreglow2_1.1.1.rmskin

Roadmap

See ROADMAP.md. Next up: GPU temperature via HWiNFO, a 3-day forecast, a settings panel and high-DPI scaling.

Accent presets

Click the glowing dot in the top-left of the header to cycle the gradient: Coreglow (cyan/violet, default) → Emerald → Sunset → Rose → Mono. Hovering shows a ring around the dot. You can also pick one directly: right-click the skin → Accent: …. Presets recolor the rings, bars, network graph and ↓/↑ speeds. The choice is saved to that skin's @Resources\Variables.inc and survives refreshes and reboots. Custom colors (Accent1, Accent2, DownColor, UpColor as R,G,B,A) still work via Edit variables.
