I dont have radeon anymore – but it is probably still called ‘catalyst control panel’ – just open that up (will be on your desktop or in your programme list) and look to see what version you have there.
Alternatively just find your gfx card in hardware and click the ‘drivers’ tab to see what driver version you have.
Wouldn’t normally auto update…. but windows has been smarter lately and offering optional updates from NVIDA as part of automatic updates… do you have that switched on?
