Windows has introduced Jump List, which is basically a list of recent documents and unique features and links for that particular program, pinned favorites, etc. By default, Windows 10/8/77 displays 10 items in the Jump List, which can of course always be changed via the Control Panel.
Jump List missing or disappeared permanently
If you find that suddenly your Jump List has gone missing or disappeared in Windows 10/8/7, you may want to try some of these troubleshooting steps:
1] Clear taskbar icons Jump List history
First clear taskbar icons Jump List history and see if it helps.
2] R-enable Taskbar Jump Lists
Else disable Taskbar Jump Lists and re-enable them and now check if it has solved your problem.
3] Rebuild Jump Lists
If you find that your taskbar explorer icon Jump List not working, you should try to rebuild Jump Lists.
4] Limit by OS
If none of this helps you, it is quite possible that the number of items in the Jump List has exceeded 999.
The Jump List of an application could disappear permanently when you use the application to open or save a new item. This issue occurs when there are already 999 items in the Jump List.
To resolve this issue, what you can do is download and apply the update package mentioned in KB2607576. This should help resolve your issue.
In Windows 10, if you want to increase the number of Jump List items, you can make use of the Registry Editor.
Hope something here helps you solve your problem!
