In this example, the program's taskbar button icon doesn't have important information in the lower right area. Don't use overlays in your program's base icon, whether your program uses overlay icons or not. Using an overlay in the base icon will be confusing because users will have to figure out that it's not communicating status. For general icon guidelines and examples, see Icons. Use overlay icons to indicate useful and relevant status only.
Consider the display of an overlay icon to be a potential interruption of the user's work, so the status change must be important enough to merit a potential interruption.
Use overlay icons for temporary status. The overlay icons lose their value if displayed constantly, so normal program status should not show an icon. Remove the overlay icon when the icon:. Exception: Your program can constantly display an overlay icon if users always need to know its status. In this example, Windows Live Messenger always displays an overlay icon so that users can always check their reported presence.
Don't display an icon to indicate that a problem has been solved. Instead, simply remove any previous icon indicating a problem. Assume that users normally expect your program to run without problems. Display either overlay icons or notification area icons, but never both. Your program may support both mechanisms for backward compatibility, but if your program displays status using overlay icons, it shouldn't also use notification area icons for status.
Don't flash the taskbar button to draw attention to a status change. Doing so would be too distracting. Let users discover overlay icons on their own. Prefer standard overlay icons to indicate status or status changes. Use these standard overlay icons:. For custom overlay icons, choose an easily recognizable design. Use high-quality 16x16 pixel, full color icons. Prefer icons with distinctive outlines over square or rectangular shaped icons. Apply the other Aero-style icon guidelines as well.
Keep the design of custom overlay icons simple. Don't try to communicate complex, unfamiliar, or abstract ideas. If you can't think of a suitable custom icon, use a standard icon error or warning icon instead when appropriate. These icons can be used effectively to communicate many types of status. Don't change status too frequently. Overlay icons shouldn't appear noisy, unstable, or demand attention. The eye is sensitive to changes in the peripheral field of vision, so status changes need to be subtle.
Don't change the icon rapidly. If underlying status is changing rapidly, have the icon reflect high-level status. Don't flash the icon. Doing so is too distracting. If an event requires immediate attention, use a dialog box instead. If the event otherwise needs attention, use a notification. Design Jump Lists to satisfy your users' goals for their everyday tasks. Your program's purpose. Think about what users are most likely to do next. For document creation programs, users are likely to return to recently used documents.
For programs that show existing content, users may want access to resources they use frequently. For other programs, users might be likely to do tasks they haven't done before, such as read new messages, watch new videos, or check their next meeting. What users care about most.
Think about why users would use the Jump List instead of other means. For example, users are more likely to care about destinations they explicitly identified as important such as Web addresses users placed on their links bar or in Favorites, or typed in. They are less likely to care about those obtained indirectly or with little effort such as Web addresses visited through redirection or by clicking links. In the incorrect example, the Jump List contains many destinations that users aren't likely to care about.
Don't make destinations too granular. Making destinations too narrow and specific can result in redundancy, with several ways to go to the same place. For example, instead of listing individual Web pages, list top-level home pages instead; instead of listing songs, list albums.
Don't fill all the available Jump List slots if you don't need to. Focus Jump List content on the most useful items if your program has only three useful items, provide only three. Log in Sign Up. Save Word.
