Steps used to test these changes

• Build the app
• Cold-launch the app
• See its jump list being the same as the Explorer's jump list
• Pin/unpin an item from the Explorer's jump list
• See that of Files also gets updated
• Do the way around of above

Is this code used at all? If not, we can remove it.

Yeah used.

Files/src/Files.App (Package)/Package.appxmanifest

Line 141 in b549af2

<Extension Category="windows.updateTask" EntryPoint="Files.App.BackgroundTasks.UpdateTask" />

We may need to put something in place to prevent stale jumplists after updating Files or Windows.

[0x5bfa]

We can do the same as what we do at the startup, clear all and fetch items from Explorer.
Should we do it?

[yaira2]

Does the update task run even if Files is closed? In that case, I think we should do this.

Now when the app is updated, the old jump list will be deleted and re-fetched from Explorer.
