Windows

Implementation

Windows support uses WMI (Windows Management Instrumentation) to query system information.

Technologies Used

• wmi crate - Rust bindings for WMI
• COM - Component Object Model
• sysinfo crate - Storage information
• CoreGraphics - Display refresh rate

WMI Tables

Information	WMI Table	Field
Manufacturer	Win32_ComputerSystem	Manufacturer
Model	Win32_ComputerSystem	Model
Device Name	Win32_ComputerSystem	Name
UUID	Win32_ComputerSystemProduct	UUID
Serial	Win32_BIOS	SerialNumber
Refresh Rate	Win32_VideoController	CurrentRefreshRate

Testing WMI Queries

You can test WMI queries in PowerShell:

# Device info
Get-WmiObject -Class Win32_ComputerSystem | Select Manufacturer, Model, Name

# UUID
Get-WmiObject -Class Win32_ComputerSystemProduct | Select UUID

# Serial number
Get-WmiObject -Class Win32_BIOS | Select SerialNumber

# Display refresh rate
Get-WmiObject -Class Win32_VideoController | Select CurrentRefreshRate

Troubleshooting

WMI Service Issues

If queries fail, check the WMI service:

# Check service status
Get-Service winmgmt

# Restart service
Restart-Service winmgmt

# Verify repository
winmgmt /verifyrepository

# Repair if needed
winmgmt /salvagerepository

Virtual Machines

On virtual machines, some information may be missing or show hypervisor info:

• VMware: Shows "VMware, Inc." as manufacturer
• Hyper-V: Shows "Microsoft Corporation"
• VirtualBox: Shows "innotek GmbH"
