I had a few users mention that the Google Chrome logo had disappeared from the icon to launch the software. While Chrome functioned as expected, the issue is aesthetic only but I can see why it would become frustrating!

I'm not necessarily sure what caused this issue to occur however I have not received reports of the issue happening again after implementing this fix. From further looking online it seems like this issue is rather common without a solid fix. With this in mind, the below solution may not work for you.
Solution Link to heading
- Unpin Chrome from taskbar
 - Locate Chrome in the start menu and right click "Properties"
 - Click "Change Icon..."
 - Replace the directory that is currently being looked in with 
%ProgramFiles% (x86)\Google\Chrome\Application\chrome.exeand hit enter - The Google Chrome icon should now be viewable in the below window
