Microsoft Store Background Task

Every now and again when I open my task manager and check processes I see this 'From Microsoft Background Task' and it has the windows logo as its little logo. Whenever I click on it (just a normal left click) it closes itself and doesn't come back. I'm scared this is a RAT or Bitcoin miner or something of the sort. May 20th 2016 UPDATE: We have a solution to disabling the STORE in Windows 10 Pro using a Group Policy Object. To avoid confusion I started a new post HERE. JANUARY 28 2016 UPDATE: I have found this GPO to cause the STORE to fail to download apps but it does not block the store outright like it did in Windows 8. “Roy” in Microsoft Partner Support, worked with the Windows Dev Team to.

Project Professional 2019 Project Professional 2016 Project 2010 Project Online Desktop Client Project Professional 2013 Project Standard 2010 Project Standard 2013 Project Standard 2016 Project Standard 2019In Project, an indented task becomes a subtask of the task above it, which becomes a summary task. A summary task is made up of subtasks, and it shows their combined information.To create a subtask or a summary task, indent a task below another one. In the Gantt Chart view, select the task you want to turn into a subtask, then click Task Indent.The task you selected is now a subtask, and the task above it, that isn’t indented, is now a summary task. Tip: Click Outdentto move the task back to the level of the task above it.Show or hide subtasksTo show or hide all subtasks for all summary tasks in Project, in the View tab, click Outline in the Data section, and then click All Subtasks to show all the subtasks or click one of the Level options below it to show all the subtasks up to that level.To show and hide all subtasks for a single summary task, simple click the expand or collapse button to the left of the summary task name to show them or hide them respectively. Tip: Outline numbers can be useful for viewing the organization of your tasks at a glance. Tips for organizing and working with outlined tasks.If your tasks aren’t indenting or outdenting, there could be a variety of reasons why.When organizing the tasks for a project, you should plan the outline for the project in one of two ways; the top-down method or the bottom-up method.With the top-down method, you identify the major phases first and then break the phases down into individual tasks.

The top-down method gives you a version of the plan as soon as you decide on the major phases.With the bottom-up method, you list all the possible tasks first, and then you group them into phases. Note: Don’t forget to after you finish organizing them.

Subtasks and summary tasks create structure, but they don’t create task dependencies.You can include the project as a summary task.When you move or delete a summary task, Project moves or deletes all of its subtasks. Before you delete a summary task, outdent the subtasks you want to keep.You can without changing each subtask.

But be careful — changing the duration of the summary task does not necessarily change the durations of the subtasks.Avoid assigning resources to summary tasks. Assign them to the subtasks instead, or you might not be able to resolve overallocations.Summary tasks don’t always add up. Some summary task values (cost and work) are the total of the subtask values, others (duration and baseline) aren’t.

Support your app with background tasks. 9 minutes to read.

Contributors.In this articleThe topics in this section show you how to make lightweight code run in the background in response to triggers. You can use background tasks to provide functionality when your app is suspended or not running. You can also use background tasks for real-time communication apps like VOIP, mail, and IM. Playing media in the backgroundStarting in Windows 10, version 1607, playing audio in the background is much easier.

See for more information. In-process and out-of-process background tasksThere are two approaches to implementing background tasks:. In-process: the app and its background process run in the same process. Out-of-process: the app and the background process run in separate processes.In-process background support was introduced in Windows 10, version 1607, to simplify writing background tasks. But you can still write out-of-process background tasks. See for recommendations on when to write an in-process versus out-of-process background task.Out-of-process background tasks are more resilient because the background process can't bring down your app process if something goes wrong. But the resiliency comes at the price of greater complexity to manage the cross-process communication between the app and the background task.Out-of-process background tasks are implemented as lightweight classes that implement the interface that the OS runs in a separate process (backgroundtaskhost.exe).

Register a background task by using the class. The class name is used to specify the entry point when you registering the background task.In Windows 10, version 1607, you can enable background activity without creating a background task. You can instead run your background code directly inside the foreground application's process.To get started quickly with in-process background tasks, see.To get started quickly with out-of-process background tasks, see. TipStarting with Windows 10, you no longer need to place an app on the lock screen as a prerequisite for registering a background task for it. Background tasks for system eventsYour app can respond to system-generated events by registering a background task with the class. An app can use any of the following system event triggers (defined in ) Trigger nameDescriptionInternetAvailableThe Internet becomes available.NetworkStateChangeA network change such as a change in cost or connectivity occurs.OnlineIdConnectedStateChangeOnline ID associated with the account changes.SmsReceivedA new SMS message is received by an installed mobile broadband device.TimeZoneChangeThe time zone changes on the device (for example, when the system adjusts the clock for daylight saving time).For more info see. Conditions for background tasksYou can control when the background task runs, even after it is triggered, by adding a condition.

Once triggered, a background task will not run until all of its conditions are met. The following conditions (represented by the enumeration) can be used. Condition nameDescriptionInternetAvailableThe Internet must be available.InternetNotAvailableThe Internet must be unavailable.SessionConnectedThe session must be connected.SessionDisconnectedThe session must be disconnected.UserNotPresentThe user must be away.UserPresentThe user must be present.Add the InternetAvailable condition to your background task to delay triggering the background task until the network stack is running.

This condition saves power because the background task won't execute until the network is available. This condition does not provide real-time activation.If your background task requires network connectivity, set to ensure that the network stays up while the background task runs. This tells the background task infrastructure to keep the network up while the task is executing, even if the device has entered Connected Standby mode. If your background task does not set IsNetworkRequested, then your background task will not be able to access the network when in Connected Standby mode (for example, when a phone's screen is turned off.)For more info about background task conditions, see. Application manifest requirementsBefore your app can successfully register a background task that runs out-of-process, it must be declared in the application manifest.

Mobile Plans Background Task Host

Background tasks that run in the same process as their host app do not need to be declared in the application manifest. For more info see. Background tasksThe following real-time triggers can be used to run lightweight custom code in the background: Real-time triggerDescriptionControl ChannelBackground tasks can keep a connection alive, and receive messages on the control channel, by using the. If your app is listening to a socket, you can use the Socket Broker instead of the ControlChannelTrigger.

For more details on using the Socket Broker, see. The ControlChannelTrigger is not supported on Windows Phone.TimerBackground tasks can run as frequently as every 15 minutes, and they can be set to run at a certain time by using the. For more info see.Push NotificationBackground tasks respond to the to receive raw push notifications.NoteUniversal Windows apps must call before registering any of the background trigger types.To ensure that your Universal Windows app continues to run properly after you release an update, call and then call when your app launches after being updated. For more information, see.Limits on the number of trigger instances: There are limits to how many instances of some triggers an app can register. An app can only register, and once per instance of the app. If an app goes over this limit, registration will throw an exception.

System event triggersThe enumeration represents the following system event triggers: Trigger nameDescriptionUserPresentThe background task is triggered when the user becomes present.UserAwayThe background task is triggered when the user becomes absent.ControlChannelResetThe background task is triggered when a control channel is reset.SessionConnectedThe background task is triggered when the session is connected.The following system event triggers signal when the user has moved an app on or off the lock screen. Trigger nameDescriptionLockScreenApplicationAddedAn app tile is added to the lock screen.LockScreenApplicationRemovedAn app tile is removed from the lock screen.Background task resource constraintsBackground tasks are lightweight. Keeping background execution to a minimum ensures the best user experience with foreground apps and battery life.

This is enforced by applying resource constraints to background tasks.Background tasks are limited to 30 seconds of wall-clock usage. Memory constraintsDue to the resource constraints for low-memory devices, background tasks may have a memory limit that determines the maximum amount of memory the background task can use. If your background task attempts an operation that would exceed this limit, the operation will fail and may generate an out-of-memory exception-which the task can handle. If the task does not handle the out-of-memory exception, or the nature of the attempted operation is such that an out-of-memory exception was not generated, then the task will be terminated immediately.You can use the APIs to query your current memory usage and limit in order to discover your cap (if any), and to monitor your background task's ongoing memory usage. Per-device limit for apps with background tasks for low-memory devicesOn memory-constrained devices, there is a limit to the number of apps that can be installed on a device and use background tasks at any given time.

If this number is exceeded, the call to, which is required to register all background tasks, will fail. Battery SaverUnless you exempt your app so that it can still run background tasks and receive push notifications when Battery Saver is on, the Battery Saver feature, when enabled, will prevent background tasks from running when the device is not connected to external power and the battery goes below a specified amount of power remaining. This will not prevent you from registering background tasks.However, for enterprise apps, and apps that will not be published in the Microsoft Store, see to learn how to use a capabilities to run a background task or extended execution session in the background indefinitely. Background task resource guarantees for real-time communicationTo prevent resource quotas from interfering with real-time communication functionality, background tasks using the and receive guaranteed CPU resource quotas for every running task. The resource quotas are as mentioned above, and remain constant for these background tasks.Your app doesn't have to do anything differently to get the guaranteed resource quotas for and background tasks. The system always treats these as critical background tasks. Maintenance triggerMaintenance tasks only run when the device is plugged in to AC power.

For more info see. Background tasks for sensors and devicesYour app can access sensors and peripheral devices from a background task with the class. You can use this trigger for long-running operations such as data synchronization or monitoring.

Unlike tasks for system events, a DeviceUseTrigger task can only be triggered while your app is running in the foreground and no conditions can be set on it. ImportantThe DeviceUseTrigger and DeviceServicingTrigger cannot be used with in-process background tasks.Some critical device operations, such as long running firmware updates, cannot be performed with the.

Such operations can be performed only on the PC, and only by a privileged app that uses the. A privileged app is an app that the device's manufacturer has authorized to perform those operations. Device metadata is used to specify which app, if any, has been designated as the privileged app for a device. For more info, see Managing background tasksBackground tasks can report progress, completion, and cancellation to your app using events and local storage.

Your app can also catch exceptions thrown by a background task, and manage background task registration during app updates. For more info see:Check your background task registration during app launch. Ensure that your app's ungrouped background tasks are present in BackgroundTaskBuilder.AllTasks. Re-register the ones that are not present. Unregister any tasks that are no longer needed. This ensures that all background tasks registrations are up-to-date every time the app is launched.
