How to Idendify Hardwares in Windows pc?

            When you are looking for a device driver for a piece of hardware, it is useful to know the hardware id of the device.The hardware identifier is a combination of the bus type, the hardware manufacturer (or vendor) and the device identifier. In some cases additional sub-system identifiers and revision information is included to distinguish between variations of a device.

To check the hardware id for a device, follow these steps:
  1.  Open the Device Manager by type “devmgmt.msc” at the Run option in the Start menu.
  2.  In the Device Manager, right-click the device, and select Properties in the popup menu.
  3.  select the Details tab.
  4.  select the Hardware Ids in the drop down list.

As you can see in the screen shot, there can be multiple hardware ID's for a device. The top one is the most specific identifier, and going down, the identifiers are more generic. The reason this is done is to allow a device driver to be selected based on a match to any of these hardware identifiers.

The hardware manufacturer in this example is Realtek, which is identified by VEN_10EC.

Obviously this is a device for which a driver is installed already, and the manufacturer and model for the device are shown, but the hardware id is also available for unknown devices and not recognized devices.
