<p><b>Grouping/ungrouping taskbar items</b> </p><p>Try opening more than three windows of any program, such as Internet Explorer, and you will see them automatically grouped together under a single button. This happens because Windows XP, by default, enables the option of grouping similar programs. To uncheck this option, right click on a blank area of the Taskbar and select Properties. Under Properties, deselect 'Group Similar Taskbar Buttons', and then click OK. If you want to change the number of windows that can be opened, without grouping, you will have to change a registry entry. Go to Start > Run and type regedit, and press [Enter]. Navigate to the key to KEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Taskbar Groupsize. Right click on 'Taskbar Groupsize', and change the hexadecimal value to whatever you like-for example, 4, 5 or even 10. XP will now group the programs according to the number you set. </p><p><img src="http://www.hashdot.com/winxpgr.jpg" width="510" height="383" border="0" alt="" /> </p><p><b>Hiding inactive icons</b> </p><p>Windows XP automatically hides inactive icons in the System Tray. If you so wish, you can disable this option by right clicking on the Taskbar, choosing Properties, and disabling the 'Hide Inactive Icons' option. You can specify the ones you would like to be not hidden. </p>
