Disappearing icons in notification area of taskbar

. .This all i could find on the internet,not sure if it will help.
this was related to the notification area (f.k.a. System Tray). Specifically, the "Action Center" notifications were causing the taskbar to pop-up every few seconds. I went into the Taskbar properties, and selected 'Customize' within the Notification area. I chose the 'Hide icon and notification' option for the Action Center icon. I'm sure that some of the other icons could cause this issue, as well. You just need to use trial and error to figure out which one is causing the problem. OR, I suppose you could choose to hide all of the icons if you don't care to see any of them in the system tray/notification area.
Steps:
1. Right click the taskbar
2. Select Properties
3. Click the 'Customize' button in the section labeled 'Notification area'
4. Find the suspect program (Action Center, in my case)
5. Click the drop-down next to the icon of the offending program
6. Select the "Hide icon and notifications" option
7. Click 'OK' to close the Notification Customization screen
8. Click 'OK' to close the Taskbar properties menu..

The task bar is an important part of the Windows experience. Not only does it contain a variety of information including what time it is and how much battery life is left it's the way most Windows users open programs and documents. As such, the task bar disappearing is a stressful thing, but fixing this problem on your own is possible.

Auto-Hide Sometimes you may think your task bar has disappeared, but it's really just been set to "auto-hide." Move your mouse to the bottom of the screen and see if it pops up automatically. Then check all four sides of the screen. If the task bar was simply auto-hiding, disable this feature by right-clicking the task bar, clicking "Properties" and unchecking "Auto-hide the Taskbar." b> Reboot b> If your task bar disappears, and auto-hide isn't the culprit, the first thing you should do is reboot your computer this fixes the problems in most instances. Only one problem: because your task bar disappeared you can't access the "Start" menu in order to shut down the computer. Instead press "Alt," "Ctrl," and "Delete" at the same time and press "Restart" in the window that pops up after doing so. Your computer should restart, and in most cases your task bar should come back when it restarts. b> More Options b> If rebooting doesn't fix cause the task bar to reappear, your computer might have a problem starting explorer.exe, the program that displays the task bar and desktop icons in Windows. Press "Ctrl," "Shift," and "Esc" at the same time to bring up the System Manager. Then click "File," followed by "New Task (Run)" and type "explorer.exe" in the dialogue box that pops up. You now have your task bar and desktop icons back. Reboot to see if they stick around after rebooting. If not, repeat the process in the above paragraph. When you have you task bar back click "Start," then "Programs," then "Accessories," then "System Tools" and then "System Restore." Restore the computer to a time when everything was working fine by clicking that date on the calendar. Reboot to see if this fixes the problem. If none of this brought back your task bar permanently it may be time to run a repair install. Change My Task Bar b> In Windows operating systems, the taskbar shows your currently active windows and programs, shortcuts to your favorite programs, the time, your volume control, active programs and the "Start" button. You may want to change the taskbar so it has a different look or to customize it to suit your needs when using your computer. Windows XP users have fewer options than Windows Vista or Windows 7 users, but all operating system owners can make changes to the taskbar.

Right-click in your taskbar. Left-click on "Lock the taskbar" if it is currently checked. Otherwise, click back onto the taskbar. Click on any empty area of the taskbar. Drag the taskbar to the position (bottom, top, left or right side of the screen) you desire, and release it. Re the taskbar by moving your cursor to where the taskbar ends. Your cursor will change to a two-way arrow. Left-click and drag the taskbar until it reaches the you want. Move your cursor over the series of separator bumps between the Start button and the Quick Launch menu, and the Quick Launch menu and the active programs section of the taskbar, to alter the of the Quick Launch menu and the active programs area. Right-click the taskbar, and left-click on "Lock the taskbar" once you've completed the changes you wish to make. b> Change Taskbar Options b> Right-click on the taskbar, and left-click on "Properties." Modify the taskbar settings so that it appears the way you like. You can decide whether to show the Quick Launch menu (a series of icons for your most commonly used programs), to show thumbnails for your active programs in Windows 7 and Windows Vista and to group similar active programs, and to automatically hide the taskbar or to always have it on top of other windows. Click on the "Notification" tab in Windows 7 or Vista to modify the way the notification area to the far right appears. Stay on the taskbar tab in Windows XP. Hide inactive icons, and decide which information to show, including the clock or the volume, power and network icons in Windows 7 and Vista. Click on the "Customize" button to specify which programs or notifications should always show, never show or grow inactive with disuse. Click on the "Toolbars" tab in Windows 7 or Vista to specify which toolbars you wish to see in the taskbar. Your options will vary according to the programs you have installed on your computer but may include the Quick Launch, address bar and links toolbars. Click the "Apply" button, then "OK" once you have made the changes you desire. Hope this helps.

My suggestion is to set the 'Start Menu' and 'Notification area' to default settings.

1) Right-click the Start icon and select Properties.
Click Taskbar tab > click 'Customize...' in Motification area' section.
Uncheck 'Always show all icons and notifications on the taskbar' (it looks like you have this on)
Click 'Restore default icon behaviors'
test to see if taht fixes the issue.

If all is OK, Re-check the 'Always show all icons and notifications on the taskbar' if you like and test again.

I hope this helps.

Do you have Windows 7? If so, you can right-click on the bottom right corner of your desktop (try right-clicking the time/date), where the icons for volume control, wireless, battery, etc... should be and select Properties. You should then see a screen where you can turn on/off the icons/notifications for battery power (sometimes my volume control disappears and i have to do this.
Otherwise you can go here, Control Panel\All Control Panel Items\Notification Area Icons and you should find the same thing. Then just turn on your battery power icon/notifications.
Hope this helps.

Volume Control - The volume icon does not appear in the notification area (system tray)
Go to Start/Control Panel/Sounds and Audio Devices.
On the Volume Tab under Device Volume, put a check in the box that reads: Place volume icon in the taskbar.(Classic View)

If that has been tried:
Place your XP CD in then go to Start/Run and type in:
EXPAND -R X:\I386\powrprof.dl_ C:\Windows\System32 (X- is your CD location)
Once done: Go to Start/Run and type in: regsvr32 stobject.dll

On Windows Vista/7:
Right-click the taskbar and select "Properties." The list of system icons in the "Notification Area" tab includes the power icon. Check the box next to it to enable this icon in the taskbar.
On Windows XP:
Right-click a blank area on the Desktop and select "Properties." Go to Screen Saver and click on Energy. In Advanced Option you could check the checkbox so the icon will re-appear in the task bar.
