i'm so exited to know how to be updated - and how it works- from local pcs :)

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

Thank you Shawn. I added this as Option Two in the tutorial for others. :)

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.
