Hi @dream2big,

Welcome to HP Support Community!

We noticed that this thread hasn't had any updates in a while since your original post; while this is rare, we didn't want this post to remain unanswered, so here's the solution to your query. We hope it helps you and everyone viewing this post 😊

We understand you’re seeing an "Unknown Device" under Other Devices in Device Manager, with the Victus by HP 15L Gaming Desktop TG02-0000i.

It looks like this device is associated with Microsoft’s Hyper-V Virtual Switch Protocol—specifically the "Microsoft Virtual Machine Bus Network Adapter", part of the virtualization services in Windows 11.

This adapter is typically not needed unless:

• You're using Hyper-V (Windows virtualization platform),
• Or you recently enabled virtualization features in Windows Features (e.g., "Virtual Machine Platform", "Windows Hypervisor Platform", or "Hyper-V").

Option 1: Disable Unused Virtualization Features (If Not Needed)

If you're not using virtual machines, disable unused services:

1. Press Windows + R, type:
   optionalfeatures
   and press Enter.
2. In the Windows Features window, uncheck the following if enabled:
• Hyper-V
• Virtual Machine Platform
• Windows Hypervisor Platform
3. Click OK and reboot your system.
4. Open Device Manager, right-click the "Unknown device" and select Uninstall device.
5. Restart your PC. It should now be gone.

Option 2: Manually Reinstall the Driver (If You Do Use Hyper-V)

If you are using Hyper-V or WSL2, try reinstalling the Virtual Switch driver:

1. Open PowerShell as Administrator and run: Get-NetAdapter

If the virtual switch is listed, try disabling and re-enabling it:

Disable-NetAdapter -Name "vEthernet (Default Switch)" -Confirm: $ false

Enable-NetAdapter -Name "vEthernet (Default Switch)"

1. Or reinstall Hyper-V components:

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

1. Reboot after each step.
