As you may already know, Windows 10 tracks and stores information about which documents and which folders and files you have opened recently. This information is used by the OS to provide quick access to documents via jump lists when you need them again. If you need to remove this info due to privacy concerns or for some other reason, you will find that in Windows 10 this operation can be a bit confusing. Here is how you can disable jump lists in Windows 10.

- In the right pane, create or modify the 32-bit DWORD value named Start_TrackDocs. Set its value data to 0 to disable the jump lists feature. Note: To restore defaults, set it to 1.

That’s it.
