    Choose How Windows and Store App Updates are Downloaded in Windows 10


    Windows Update Delivery Optimization
    lets you get Windows and Store app updates from sources in addition to Microsoft. This can help you get updates and apps more quickly if you have a limited or unreliable Internet connection. And if you own more than one PC, it can reduce the amount of Internet bandwidth needed to keep all of your PCs up-to-date. Delivery Optimization also sends updates and apps from your PC to other PCs on your local network or PCs on the Internet.

    When configuring Delivery Optimization on Windows 10 devices, the first and most important thing to configure is the Download mode, which dictates how Delivery Optimization downloads Windows updates.

    You can choose to download updates only from Microsoft, Microsoft and PCs on your local network, or Microsoft and PCs on your local network and internet.

    Delivery Optimization works in two ways.

    Download updates and apps from other PCs

    In addition to downloading updates and apps from Microsoft, Windows will get updates and apps from other PCs that already have them. You can choose which PCs you get these updates from:

    PCs on your local network. When Windows downloads an update or app, it will look for other PCs on your local network that have already downloaded the update or app using Delivery Optimization. Windows then downloads parts of the file from those PCs and parts of the file from Microsoft. Windows doesn’t download the entire file from one place. Instead, the download is broken down into smaller parts. Windows uses the fastest, most reliable download source for each part of the file.

    PCs on your local network and PCs on the Internet. Windows uses the same process as when getting updates and apps from PCs on your local network, and also looks for PCs on the Internet that can be used as a source to download parts of updates and apps.

    Send updates and apps to other PCs

    When Delivery Optimization is turned on, your PC sends parts of apps or updates that you’ve downloaded using Delivery Optimization to other PCs on your local network, or on the Internet, depending on your settings.

    Delivery Optimization uses locally cached updates. In cases where devices have ample local storage and you would like to cache more content, or if you have limited storage and would like to cache less, use the following settings to adjust the Delivery Optimization cache to suit your scenario:

    This tutorial will show you how to choose a download mode for Delivery Optimization of Windows and Store app updates in Windows 10.

    You must be signed in as an administrator to choose how Windows Updates are delivered.

    Assign this value via the command line or through GPO


    If you're looking to automate this, you can modify the following registry entry:

    Code:
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DeliveryOptimization\Config]
    ; off
    "DownloadMode"=dword:00000000
    ; lan only
    "DownloadMode"=dword:00000002
    ; lan and web
    "DownloadMode"=dword:00000003
    Here's the appropriate reg commands:
    :: off
    Code:
    reg add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\DeliveryOptimization\Config" /v DownloadMode /t REG_DWORD /d 0 /f
    :: lan
    Code:
    reg add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\DeliveryOptimization\Config" /v DownloadMode /t REG_DWORD /d 2 /f
    :: web
    Code:
    reg add "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\DeliveryOptimization\Config" /v DownloadMode /t REG_DWORD /d 3 /f
    And to obtain the current value:
    Code:
    reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\DeliveryOptimization\Config" /v DownloadMode
    0 = off, 2 = LAN only, 3 = Web and LAN

    3 = Download updates from Microsoft, LAN, and Internet

    Forgive me if I'm being paranoid, but do we really want to download updates from external sources other than Microsoft? If I were a malicious code writer, this is what I'd be targeting.

    Yes and no. It depends on how much control you have over the network where you'll be enabling these features. I personally won't enable "internet" as a source for any of my own devices or my clients, but the LAN peering support will help a *lot* of my clients with low bandwidth and metered connections.

    I have this set to download from PCs on my internal network so I "should" only have to download from MS once.
    How can I verify that secondary PCs are only using my LAN and not MS? I tried logging onto my router and disconnecting my ADSL so that my LAN was still operational; but that stopped patch downloads in their tracks. Usage graphs from my router indicate that the traffic is still using the internet rather than the LAN.
    Thanks

    Updates still require contact with WU in order to obtain the available patch list and hashes to ensure the patches they're being offered on the LAN are valid. Further, some updates will never be offered across the LAN (such as updates to WUA). More about the process here:

    Unfortunately I didn't explain what I did properly (my apologies).
    Whilst I still had my router connected to the Internet I clicked on the Check for Updates button in Windows. My PC queried WU and got a list of the available updates and (being windows 10) immediately started to download them.
    It was at this point that I had my router disconnect from the Internet in the hope that this would force the PC to use my LAN to get the patches from another PC that had previously been patched. But this was a forlorn hope as nothing further was downloaded over the LAN, and I had to reconnect to the Internet for the patches to download from WU.
    Both PCs were Win 10 Home 64 bit but one was UEFI boot and the other was MBR boot but I don't think this should make a difference.

    But I did notice something in the link you provided
    Microsoft said:
    Depending on your settings, Windows then send parts of those files to other PCs on your local network or PCs on the Internet that are downloading the same files
    This could be read as that updates will be shared IF they are being downloaded simultaneously on multiple PCs.
