Check Installed Driver Versions Using PowerShell update from October 2014

Q: How can I quickly check what driver versions I have installed for certain hardware on my machine?

A: You can easily use the PowerShell Get-WmiObject cmdlet to see all signed drivers in a system:

Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion

The results can be filtered to show only devices that include certain words (e.g., nVidia):

Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion | where {$_.devicename -like "*nvidia*"}
