Taskbar does not Auto-hide all the time Windows 7

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.

I really hope this helped.

Hi everyone,

Under normal circumstances this does not happen. Please verify if a third party application is responsible for this behavior.

Clean boot would be the perfect practice to determine the culprit application. A clean boot helps eliminate software conflicts.

Steps to perform clean boot:

   1. Click Start, type msconfig in the Start Search box, and then press ENTER.

      If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.

   2. On the General tab, click Selective Startup.

   3. Under Selective Startup, click to clear the Load Startup Items check box.

   4. Click the Services tab, click to select the Hide All Microsoft Services check box, and then click Disable All.

   5. Click OK.

   6. When you are prompted, click Restart.

   7. After the computer starts, check whether the problem is resolved.

If the issue is resolved check which third party is causing the problem by referring the steps from the link given below:

How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7**http://support.microsoft.com/kb/929135**

Note: Ensure  to put the computer to normal state.

**To Reset the computer to start as usual:**1. Click Start, type msconfig.exe in the Start Search box, and then press ENTER.

If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

2. On the General tab, click the Normal Startup option, and then click OK.
3. When you are prompted to restart the computer, click Restart.

Hope this helps in determining the application causing this behavior.

Dear Shinmila H,

Thank you for your reply.  I disabled Avast Antivirus, which I have used since before I loaded Windows 7, downloaded and ran Microsoft Security Essentials, which found no issues. These actions created no change in the Taskbar behavior.  BTW, I had already deactivated the 'Lock the Taskbar' button.  When I pull up the Taskbar properties, uncheck the 'Autohide' button, check 'apply', then recheck the 'Autohide' button, then check 'apply', the taskbar disappears for just one second, then reappears to stay.  Later, it may autohide, but never does when I run Mozilla Thunderbird email server.

Regards,
