Google Chrome always says, "Google Chrome was not shut down properly"
Solution 1:
This was just happening to me too. I found inside this file "%UserProfile%\AppData\Local\Google\Chrome\User Data\Default\Preferences" near the bottom of the file (inside the Profile section) this line:
"exit_type": "Crashed"
Once I modified the line to read "normal" instead of "Crashed" like this:
"exit_type": "normal",
The problem disappeared.
Solution 2:
Couple potential problems and fixes. Firstly check Chrome isn't sitting in your Windows taskbar (bottom right). If it is:
Right-click > Uncheck "Run Chrome in the background"
Additionally to this you might want to have a look in your msconfig
just to see if Chrome is booting on startup.
Could be a problem with an extension. Turn them off via chrome://extensions/
and see if this solves it. Should this be the issue simply turn them back on one at a time till you find the culprit.

See if either of these solves it.

Yep, I have had exactly the same problem for quite a while now. REALLY annoying. For me, Chrome even started two separate instances, one of them showing the error, the other one behaving normally.
I managed to fix it by going to Settings / Advanced Settings and turning OFF the "Continue running background apps when Google Chrome is closed" option (found this in this thread, suggested by Ashtangakasha)
