It looks like the Windows 8 weather app is not using a background task. Any ideas? Unfortunately these are the parameters a third-party app such as your has to deal with. The Weather app that is pre-installed is not subject to these limitations since it is a Microsoft app - they aren't subject to the same limitations that we are.

The pre-installed weather app is using periodic tile updates to update it's live tile every 30 minutes. A background task is not necessary with periodic updates - once periodic updates are set up by an app, Windows will retrieve the new live tile content whether the app is running or not.

Refreshing the data every minutes seems a bit excessive. For a weather app, it shouldn't be necessary to update the tile more frequently than every 30 minutes. That being said, if you want to update the tile more frequently than every 30 minutes, you'll need to employ either a background task, or push notifications.

Each have their drawbacks. Background tasks have a minimum 15 minute granularity, and as you stated in your question, can be made to run less frequently by the user.

Push notifications add complexity, but can be used to deliver immediate live tile updates. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

An optional server name value can be specified to configure Windows Update Agent to download updates from an alternate download server instead of the intranet update service.

If the setting is set to Enabled , the Automatic Updates client connects to the specified intranet Microsoft update service or alternate download server , instead of Windows Update, to search for and download updates. Enabling this setting means that end users in your organization don't have to go through a firewall to get updates, and it gives you the opportunity to test updates after deploying them.

If the setting is set to Disabled or Not Configured , and if Automatic Updates is not disabled by policy or user preference, the Automatic Updates client connects directly to the Windows Update site on the Internet. The alternate download server configures the Windows Update Agent to download files from an alternative download server instead of the intranet update service.

The option to download files with missing Urls allows content to be downloaded from the Alternate Download Server when there are no download Urls for files in the update metadata. This option should only be used when the intranet update service does not provide download Urls in the update metadata for files which are present on the alternate download server. If the "Configure Automatic Updates" policy is disabled, then this policy has no effect.

If the "Alternate Download Server" is not set, it will use the intranet update service by default to download updates. The option to "Download files with no Url Specifies the hours that Windows will use to determine how long to wait before checking for available updates. The exact wait time is determined by using the hours specified here minus zero to twenty percent of the hours specified. For example, if this policy is used to specify a hour detection frequency, then all clients to which this policy is applied will check for updates anywhere between 16 to 20 hours.

If the setting is set to Enabled , Windows will check for available updates at the specified interval. If the setting is set to Disabled or Not Configured , Windows will check for available updates at the default interval of 22 hours. The "Specify intranet Microsoft update service location" setting must be enabled for this policy to have effect. Any background update scans, downloads and installations will continue to work as configured.

Even when Windows Update is configured to receive updates from an intranet update service, it will periodically retrieve information from the public Windows Update service to enable future connections to Windows Update, and other services like Microsoft Update or the Microsoft Store.

When enabled, this policy will disable the functionality described above, and may cause connection to public services such as the Microsoft Store, Windows Update for Business and Delivery Optimization to stop working. This policy applies only when the device is configured to connect to an intranet update service using the "Specify intranet Microsoft update service location" policy. Specifies the target group name or names that should be used to receive updates from an intranet Microsoft update service.

This allows admins to configure device groups that will receive different updates from sources like WSUS or Configuration Manager. If the setting is set to Enabled , the specified target group information is sent to the intranet Microsoft update service which uses it to determine which updates should be deployed to this computer.

If the setting is set to Disabled or Not Configured , no target group information will be sent to the intranet Microsoft update service. If the intranet Microsoft update service supports multiple target groups, this policy can specify multiple group names separated by semicolons. Otherwise, a single group must be specified. This policy applies only when the intranet Microsoft update service the device is directed to is configured to support client-side targeting.

If the "Specify intranet Microsoft update service location" policy is disabled or not configured, this policy has no effect. This policy setting allows you to manage whether Automatic Updates accepts updates signed by entities other than Microsoft when the update is found on an intranet Microsoft update service location.

If you enable this policy setting, Automatic Updates accepts updates received through an intranet Microsoft update service location, as specified by Specify Intranet Microsoft update service location , if they are signed by a certificate found in the "Trusted Publishers" certificate store of the local computer.

If you disable or do not configure this policy setting, updates from an intranet Microsoft update service location must be signed by Microsoft. Updates from a service other than an intranet Microsoft update service must always be signed by Microsoft and are not affected by this policy setting. To add more flexibility to the update process, settings are available to control update installation.
