Taskbar does not Auto-hide all the time Windows 7

The solution to this is Simple.

One of your little icons on the bottom right has a message for you. This message however does not appear on the Taskbar so it's a lost little message! Rather than languishing in the void forever the friendly Taskbar is trying to bring your attention to poor little fellow. Simply click the 'Show Hidden Icons' little triangle. Now click each icon in turn and see if any of them have a message for you. If they do accept the message and return the messenger to the source.

I found one about USB drivers, telling me they had correctly installed. I closed this and voila problem gone.

A few days later Adobe had one asking if I wanted to install it's update, I uninstalled Adobe altogether.

Hope this helps someone

Sign me up for the same problem, and it's actually quite annoying, but i did find solutions on another forum posting the same issue, and a guy came up with this.

Most of the solution are really dumb. Do these people have jobs?

No wonder the US is #9.

Open Task Manager and Regedit.

++ on the Start Menu & select 'Exit Explorer'

In Regedit, navigate to:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\Streams\Desktop]

delete the value named 'Toolbars'.

In Task Manager, select 'File' -> 'New Task' -> type 'explorer' to restart

the shell.

If that doesn't do the trick, repeat deleting 'TaskbarWinXP' as well. (I

can't test right now).

 

And it's reported by other users to have worked as intended, but i will say that i have not tried this solution.

I also found this which seems to explain what Shinmila H couldn't, why this happens.

And yes, i tried this solution, and it worked like i charm.

Often times Windows will refuse to hide because it mistakenly believes there is still a tooltip balloon open. (I see this a lot myself with APC's Powerchute Personal Edition.) Unfortunately the only way to get your taskbar to properly hide again (and I don't mean uncheck the "Keep the taskbar ontop of other widows" option for a quick fix) is to restart the machine so that Windows resets the tooltip balloon status. What a pain!

Thankfully through my inability to let it go and hatred for this problem I have written a file that will fix this! (Works great on my Vista machine!) All the program does is overwrite the phantom tooltip balloon and then clear the tooltip balloon and Tahdah!

The tooltip will stay up for 10 seconds so that you can read the info on it (just telling you what it does and how you can contact me if you have any problems). You can close this tooltip balloon like any other by clicking on it, or if you mouse over the program tray icon it will close itself instantly.

And here is a pic of how it looks in action.

I really hope this helped.

I must not understand but, I don't know how to: "Open Task Manager and Regedit.". I went to Task Manager but can't find "Regedit" there.

And when I get to "Regedit" , where ever it is, should I back it up?

It isn't "The good old days", it is default.  In the "Good old days" there was a setting that could be used "Do not flash notification in tray", but that option was taken away, by Microsoft, intentionally, from ALL applications.  

I would like to know why this still happens as it has been a problem since windows XP that has NEVER been resolved.  The excuse I get from MS is that "No one hides the taskbar".  Considering that this is a very long standing issue, I found that response surprising.

BTW, the worst culprit for locking the Taskbar open was the new version of MSN after MS made it so that it was impossible to minimize it to the system tray.
