Change the Number of Recent Items in Jump List

When you right-click on a taskbar icon, you will see a list of documents, pictures, songs, or websites depending on the program that you had right-clicked. For example, right-clicking Internet Explorer will display a list of frequently viewed websites, pinned websites (if any). By default, there are 10 items displayed in the jump list. You can change this number and can increase or decrease the number by performing the following steps:
1. Right-click on an empty space on the taskbar and click on Properties.
2. From the Taskbar and Start Menu Properties dialog box, click on the Start Menu tab. Click Customize… button.
3. From the Customize Start Menu dialog box, under Start menu size section, set a new value for Number of recent items to display in Jump Lists option.
4. Click OK twice.
