How to tell which version is installed?
Before starting the update, check on the manufacturer’s website to see the latest version available.
Compare it with the one installed in your system, as follows:
Open the Control panel > Device manager, and then press the Controller button in ‘Properties’ of the device you are interested in.
Here you will find the name of the manufacturer or supplier, plus the date and the version of the device; this last piece of information is what you need. Just check both numbers to see if you have the latest version.
