It worked .... the first time.
But I closed chrome, and reopened just to be certain, and sure enough, new icon -.-
And Thanks for the welcome
I've done a little search and it seems this is an ongoing issue, starting back in 2009.
Try doing it this way, with Chrome open this time, unpin both icons if 2 are showing, then repin the one that represents the open window.
Also, try Troubles advice.
Let us know the outcome

Download the "alternate installer for all user accounts" version from here Alternate (offline) Google Chrome installer (Windows) - Google Chrome Help to a folder of your choosing on your computer.
Uninstall Chrome
Reboot your computer
Run the installer you downloaded above from the folder where you saved it.
Good Luck

It works for me.revert back to my old friend Opera to avoid this taskbar issue.
