Can the eventual Disappearance of Recent Excel Files on the Taskbar be stopped? Pinned ones remain.

As I use Excel, the recent files list on the Taskbar grows. After a while, all the recent ones disappear. Any new recent files no longer show up while the pinned files remain accessible on the Taskbar. To get the Recent Files list started again. I look up how to clear them. Then I lose the pinned ones too as well. Afterwards I rebuild the pinned list. I never remember how to clear the list but search around to find out how to reset. I often lose the Word and Acrobat lists too.

Can I stop the disappearance? Thinking that once the list gets full, whatever number that may be, I will occasionally remove recent files by right clicking on them. Nevertheless, the recent ones disappear and no new ones are added.

I have had the DWORD in this Redirecting already set to 60. I recently lowered it to 20.

Thanks,
Jeff

Not sure if it applies with files but when I open a number of programs some will go into an 'overflow' link on the Taskbar shown by 3 horizontal dots. Clicking the dots gives the additional items.

This is what I see. There used to be a lot of unpinned recent files. beneath the pinned ones.

I have changed the Maximum Number in Jump Lists already. This works for a while then stops. The way I get it to work is clear out everything and start all over again rebuilding my pinned lists. Then the unpinned list grows and then disappears.
