Or find matching driver by date/size:

The specific contents of oem61.inf will depend on the device driver it is associated with. However, here is an example of what the file might look like:

Get-WindowsDriver -Online | Where-Object $_.OriginalFileName -like "*oem61.inf"

Use the PnPUtil tool by typing pnputil /enum-drivers . This will list all third-party drivers, showing the "Published Name" (e.g., oem61.inf) alongside the "Original Name" and the "Provider Name" (e.g., Realtek, Intel, or HP).

is a generic name assigned by Windows to a third-party device driver during installation. Unlike system-native drivers that have permanent names (like keyboard.inf ), Windows renames every external driver to an "OEM" format (e.g., oem0.inf , oem1.inf ) and stores it in the C:\Windows\INF directory.
