You know one can acces to the recent files/folders on explorer or other programs by right-clicking on them in the taskbar.
For some time, I've no more list, nowhere. I've no more history when I right-click on Explorer (or other programs such as Notepad, Paint) in the taskbar. And the tasks associated to programs such as Media Player don't work : I click on them and... nothing.
However it's worked properly before.
Do you know what is the problem and how to repair ? (I've the impression a registry key is missing or similar problem
