I'm building an inventory system for GPUs and looking to find a way to query GPU firmware version. I have tried the WMI query for Video Controller, but it only returns driver version and driver date.
Get-WmiObject -Query "Select * From Win32_VideoController"

For AMD GPUs, if I go to the AMD Radeon Software, it lists the firmware version.
I'm sure NVidia has a similar utility. But I do not know what kind of GPU exists on a system (or even if it has one). I need a generic solution which can be queried through the command line. I'd really appreciate any help here. Thanks!

Code:
reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000\ >biosinfo.txt
findstr "HardwareInformation.BiosString" biosinfo.txt
I'm not sure though if the UUID is always the same :confused:

Where did you get this ID from - 4d36e968-e325-11ce-bfc1-08002be10318? Asking because I see a ton of entries under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\.
