Get-PSDrive -PSProvider FileSystem | Select Name, @{N='Used(GB)';E={[math]::Round($_.Used/1GB,1)}}, @{N='Free(GB)';E={[math]::Round($_.Free/1GB,1)}}, @{N='Total(GB)';E={[math]::Round(($_.Used+$_.Free)/1GB,1)}}
```

### 2. Memory
```powershell
$os = Get-CimInstance Win32_OperatingSystem; [PSCustomObject]@{TotalGB=[math]::Round($os.TotalVisibleMemorySize/1MB,1); FreeGB=[math]::Round($os.FreePhysicalMemory/1MB,1); UsedPct=[math]::Round((1-$os.FreePhysicalMemory/$os.TotalVisibleMemorySize)*100,1)}
```

### 3. Top Processes (by memory)
```powershell
Get-Process | Sort WorkingSet64 -Descending | Select -First 10 Name, @{N='MB';E={[math]::Round($_.WorkingSet64/1MB,1)}}, CPU
```

### 4. Network Connectivity
