How to Prevent Recent Excel Files from Disappearing on the Taskbar, While Pinned Ones Stay Put

When using Excel, the recent files list on the Taskbar used to grow continuously. However, after a certain point, all the recent files would disappear on their own. Even though the pinned files remained accessible on the Taskbar, the new recent files would no longer show up. To restart the Recent Files list, I would typically look up instructions on how to clear them, only to realize that doing so would also erase the pinned files. In these instances, I would have to rebuild the pinned list from scratch. Recurrently, I struggled to remember the exact steps to clear the list and had to search for how to reset it each time. Additionally, I often noticed that the lists for Word and Acrobat disappeared as well.

Lately, I had set the DWORD in the Redirecting to 60, but I recently adjusted it to 20 to see if it made any difference.

Is there a way to prevent the recent files from disappearing? I assumed that once the list became full, I could occasionally remove some recent files by right-clicking on them. However, regardless of this effort, the recent items would vanish without new ones being added.
