System Monitor for Windows

See CPU, memory, disk and network on your Stream Deck keys

To show CPU and memory usage on a Stream Deck, add System Monitor for Windows and drag CPU, Memory, Disk or Network onto a key. Each key shows a live number, read locally from Windows every 2 seconds, so you see how hard your PC is working without switching windows.

Get it on the Elgato Marketplace

Stream Deck plugin · Works on Windows 10 or later with the Stream Deck app 6.9 or later.

What you can do

• CPU: total usage in % with a 60-second graph.
• Memory: percent in use and GB used of your total, with a 60-second graph.
• Disk: how full a drive is and the space left. Press the key for the next drive (C:, D:, ...).
• Network: download or upload speed of your Ethernet and Wi-Fi adapters, with a graph. Press the key to switch between the two.
• Five looks per key: Classic, Neon, Ring, Bars and Solid. Ring and Bars show a gauge for CPU and memory.
• Warning colors at a glance: CPU and memory keys turn yellow at 70% and red at 90%; disk keys at 80% and 95%.
• Light on resources: one shared timer, and measuring stops when no System Monitor key is shown.
• Runs entirely on your PC, with no account, no online service, no data collection and no telemetry.

Questions

Limits

• Network speed is read through Windows PowerShell. If it is blocked, the network key shows "--" and the other keys keep working.
• Traffic that stays inside your PC is not counted; only physical adapters (Ethernet, Wi-Fi) are.
• CPU usage is Windows "% Processor Time"; Task Manager on Windows 11 uses a different measure and can read higher.
• Windows only (Windows 10 or later). Not for Mac.
