Win Sysinfo

win-sysinfo

System diagnostics and hardware info for Windows. CPU, RAM, battery, GPU, network, running processes, OS details. Zero external dependencies — uses built-in WMI (Get-CimInstance) and PowerShell.

Works on Windows 10/11 with PowerShell 5.1+.

"

Running Processes

Top by CPU

powershell.exe -NoProfile -Command "
Get-Process | Sort-Object CPU -Descending | Select-Object -First COUNT |
  Select-Object Name, Id,
    @{N='CPU(s)';E={[math]::Round($_.CPU, 1)}},
    @{N='MemMB';E={[math]::Round($_.WorkingSet64/1MB, 1)}} |
  Format-Table -AutoSize
"

Replace COUNT with the number of processes to show (e.g., 15).

Top by Memory

powershell.exe -NoProfile -Command "
Get-Process | Sort-Object WorkingSet64 -Descending | Select-Object -First COUNT |
  Select-Object Name, Id,
    @{N='MemMB';E={[math]::Round($_.WorkingSet64/1MB, 1)}},
    @{N='CPU(s)';E={[math]::Round($_.CPU, 1)}} |
  Format-Table -AutoSize
"

Find a Process

powershell.exe -NoProfile -Command "
Get-Process -Name '*PROCESS_NAME*' -ErrorAction SilentlyContinue |
  Select-Object Name, Id,
    @{N='MemMB';E={[math]::Round($_.WorkingSet64/1MB, 1)}},
    @{N='CPU(s)';E={[math]::Round($_.CPU, 1)}},
    Path |
  Format-Table -AutoSize
"

Replace PROCESS_NAME with a partial name (e.g., chrome, code, ollama).

Kill a Process

powershell.exe -NoProfile -Command "
Stop-Process -Id PROCESS_ID -Force
Write-Host 'Process PROCESS_ID terminated.'
"

Replace PROCESS_ID with the PID from the process list.

Startup Programs

powershell.exe -NoProfile -Command "
Get-CimInstance Win32_StartupCommand |
  Select-Object Name, Command, Location |
  Format-Table -AutoSize
"

Installed Software

powershell.exe -NoProfile -Command "
Get-CimInstance Win32_Product | Select-Object Name, Version, Vendor |
  Sort-Object Name | Format-Table -AutoSize
"

Note: Win32_Product can be slow. For a faster check of a specific program, use winget list PROGRAM_NAME (via the winget skill).

Environment Variables

powershell.exe -NoProfile -Command "
Get-ChildItem Env: | Sort-Object Name | Format-Table Name, Value -AutoSize
"

Check a Specific Variable

powershell.exe -NoProfile -Command "
Write-Host ('VAR_NAME = {0}' -f $env:VAR_NAME)
"

Common Workflows

System health check

1. win-sysinfo: system overview (uptime, OS version)
2. win-sysinfo: CPU usage + memory usage
3. win-sysinfo: battery status
4. win-files: list drives (disk space)
5. Report any issues found

Diagnose slow machine

1. win-sysinfo: top processes by CPU
2. win-sysinfo: top processes by memory
3. win-sysinfo: memory usage percentage
4. Identify resource hogs and suggest actions

Network troubleshooting

1. win-sysinfo: network adapters and IP config
2. win-sysinfo: internet connectivity test
3. Report connection status and suggest fixes

Pre-meeting check

1. win-sysinfo: battery level
2. win-sysinfo: internet connectivity
3. win-sysinfo: CPU/memory headroom
4. Alert if any issues before joining

Notes

• Fully offline — no API keys, no network (except connectivity test), no external dependencies.
• Uses WMI (Get-CimInstance) and built-in PowerShell cmdlets.
• CPU load percentage is a snapshot — use the real-time sampling command for trends.
• Battery info only available on laptops/tablets — desktops will show "No battery detected."
• Win32_Product is slow (~30s) — prefer winget list for faster software queries.
• NPU detection uses PnP device name matching — works for Intel AI Boost, may need adjustment for other NPU brands.
• For disk space info, use the win-files skill's List Drives command.
• Process kill requires appropriate permissions — elevated processes may need admin PowerShell.
• GPU VRAM via Win32_VideoController.AdapterRAM is a 32-bit field (max ~4 GB). For GPUs with >4 GB VRAM, the reported value will be incorrect. Use dxdiag or GPU-specific tools for accurate VRAM.
