Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

Open a new Explorer window.

Click View in the ribbon.

Click Options.

Under General, next to “Open File Explorer to:” choose “This PC.”

Click OK

Microsoft explains the benefits of Windows 10 Dynamic Update

Dynamic Update can help organizations and end users alike ensure that their Windows 10 devices have the latest feature update content (as part of an in-place upgrade)—and preserve precious features on demand (FODs) and language packs (LPs) that may have been previously installed. Further, Dynamic Update also eliminates the need to install a separate quality update as part of the in-place upgrade process.

From an IT perspective, using Dynamic Update reduces the need to apply separate updates to recently installed systems and makes it easier to get your devices up to date with the latest available quality update in one step.

In this blog, we’ll explore which core components are updated by Dynamic Update, how Dynamic Update is initiated, and how to enable or disable it.

What is updated by Dynamic Update?

There are several core components that can be updated by Dynamic Update, including:

Setup DU: Fixes to Setup binaries or any files that Setup uses for feature updates.

SafeOS DU: Fixes for the ‘safe OS’ that we use to update Windows recovery environment (WinRE).

Servicing Stack Update (SSU)/Critical DU: Fixes that are necessary to address the Windows 10 servicing stack issue and thus required to complete the feature update.

Latest Cumulative Update (LCU)/General Distribution Release (GDR) DU: Installs the latest cumulative quality update.

Language Pack (LP) and Feature On Demand (FOD) DU: Preserves users’ installed language packs and optional features by reinstalling them.

Driver DU: Latest version of applicable drivers that have been already published by manufacturers (OEMs and/or IHVs) into Windows Update and specifically targeted for Dynamic Update.

How Dynamic Update works

As soon as a feature update is initiated, whether from media or a Windows Update service-connected environment, Dynamic Update is one of the first steps invoked. Windows 10 Setup reaches out to the HTTPS endpoint, i.e. the Internet-facing URL hosted by Microsoft, fetches the Dynamic Update content, then applies those updates to your OS installation media, thus making the installation process go as smoothly as possible.

Based on your feedback, starting with Windows 10, version 1809, Dynamic Update content is downloaded directly from HTTPS endpoints. Prior to version 1809, Setup leveraged the in-box Windows Update client to retrieve Dynamic Update content, which required those organizations using Configuration Manager with WSUS to approve the Dynamic Update content in the WSUS console.

How do I enable or disable Dynamic Update?

Dynamic Update is enabled by default in all Windows feature update workflows unless disabled explicitly. In an interactive installation, users will be prompted automatically to choose whether to allow Dynamic Update to occur as shown below:

In an unattended installation (i.e. one that does not require user interaction and automates Windows installation using an answer file), the setting shown below will control whether Dynamic Update occurs or not. By default, it is set to True; however, to disable it, the value can be set to False.

<DynamicUpdate>
<Enable>True</Enable>
</DynamicUpdate>

The following Setup.exe command line option can also be used to specify whether Windows Setup performs Dynamic Update operations:

/DynamicUpdate {enable | disable}
setup /auto upgrade /DynamicUpdate disable

In a Configuration Manager OS upgrade task sequence, the Task Sequence Editor features a setting for “Dynamically update Windows Setup with Windows Update” to control whether Dynamic Update occurs or not, as shown below:

If a command line setting cannot be passed to Setup—for example, in Windows Update or Configuration Manager scenarios based on the software update servicing flow—the setupconfig file can be used to configure Dynamic Update options.

If Dynamic Update is not enabled, Setup will use only the files that are provided on the installation media. FODs and LPs will not be retained or migrated. Instead, after the feature update is installed, the OS will attempt to reacquire these from Windows Update. If the device is offline or cannot reach Windows Update, then the user or admin will need to manually initiate the reinstallation of the FODs and LPs from separate media or an ISO file.

How to manage Dynamic Update content in a managed environment

https://tlu.dl.delivery.mp.microsoft.com

These specific endpoints are not exclusive to Dynamic Update; instead, they are used for any content download related to Windows updates.

In a media-based scenario, you will need to download the latest Windows 10 ISO and use it as starting point for customization; for example, removing in-box applications and customizing the user interface, drivers, and applications. For Internet-connected devices, Dynamic Update content will be downloaded directly from HTTPS endpoints. For devices not connected to the Internet, you will first need to download all Dynamic Update content and then patch your media image before initiating Setup. This makes it easier to get your device up to date with the latest available quality update in one step.

To learn more about the process of approving and downloading Dynamic Update content via WSUS for Windows 10, version 1803 and prior, see Using Dynamic Update with WSUS to install Windows 10 feature updates.

In a future blog post, we’ll explore additional scenarios where Dynamic Update can be leveraged for end users and commercial customers.
