App access to tasks

Recommendation

Depends

You can turn it off if you do not use to-do lists in Store apps; on a shared computer, the restriction is especially appropriate, as the visible BoosterX hint suggests.

This permission does not disable the system Windows Task Scheduler.

What changes

The toggle prevents supported Store/UWP apps from reading and modifying user tasks — to-do lists, reminders and due dates. The same decision at the global level is the tasks section toggle on the page “Settings” → “Privacy” (in Windows 11 — “Privacy & security”). The visible BoosterX description names the main consumers: To Do and tasks from mail accounts. An app sees task names, due dates and reminders; after the restriction, access to this list is closed, while the tasks themselves remain in the account.

Exceptions and differences

The restriction does not disable the classic Windows Task Scheduler: its system background jobs live by a different mechanism and continue to run. Browser to-do lists and ordinary Win32 programs are not covered by this permission. The set of “Settings” pages differs between Windows 10 and Windows 11 — check whether the section exists on your system.

How to verify the result

Open the tasks section in “Windows Settings”: the global toggle is set to “Off”, and “Task Scheduler” from the “Start” menu still opens and shows its tasks. Direct observation of a specific app’s behavior is not part of the check.

How to change and revert

Open “Optimization” → “Privacy” → “App permissions” → “App access to tasks”, move the toggle to “On”: BoosterX will apply the restriction on access to tasks. Click “Apply”. If “Instant apply” is enabled, a separate button is not required. To revert, move the toggle to “Off” and apply the change again: BoosterX will return Windows to its default state with access to tasks allowed.
