How to hide the system tray icons ?

Windows displays icons for active and urgent notifications, and hides inactive ones. You can change the behavior for items present in the system tray. Sometimes, it annoys when there are too many system tray icons. They are also not needed to be shown always. Cleaning the system tray also provides more space on the task bar which can accommodate more number of windows.

Actually this feature is provided by much software by themselves but some don't provide this (e.g.: anti-viruses). They can also be forced to hide by this trick.

1. Right click on green colored start menu.
2. Select properties.
3. Navigate to taskbar (by default it is only active)
Then you can see a window similar to the one shown in the picture.
4. For every item, there are three options namely always hide, always show and hide when inactive.
5. Select the item for which you want to change the settings.
6. Click ok.

You are done, you can use this to keep an item to appear or hide permanently.
This is a very easy process to hide the system tray icons, through which you can get rid of annoying and useless icons. I assume that you know what the system tray icons are!
