Changing Product Code cannot be identified

Hello,
When I connected my PC to the Internet this window message popped-up and nothing happened after I pressed OK. It doesn’t appear all the time but I would like to get rid of it. Can anyone help me please to fix this ? Why does it appears ?
Thank you !
