Windows 7 Google chrome is opening a new window that's not pinned to my task bar

So I have Windows 7 and I have google chrome pinned to my task bar at the top. Whenever I click on it, it starts up for a moment on the part that's pinned, then it opens up a new one at the bottom of my task bar. I've tried pinning the newly opened window to my task bar instead, but whenever I restart my computer it does the same thing. I don't know if this is a problem with Windows or with Google Chrome but I would just really like to fix it.

I'd say, uninstall Google Chrome and reinstall it. Be sure it's the latest upgrade. Also be sure you have the latest Windows updates. Sounds like a glitch, not necessarily harmful, but annoying. "A piece of me doesn't really work with a piece of you". You know?

I have tried uninstalling and re installing it MANY times. And yes my computer is up to date.

It could be you have several profiles open? Otherwise, you may want to check Issue 91650 - chromium - Multiple icon Google Chrome in taskbar when use profil - An open-source browser project to help move the web forward. - Google Project Hosting
