In Windows 10, especially its later versions, 1709 and 1803, some new cmdlets for the Delivery Optimization feature have been implemented. Delivery Optimization is a new form of download and sharing technology in comparison to BITS. It has some additional capabilities and can share store and OS updates in the intranet and internet. You definitely need to investigate how to configure the settings for your environment.

You can find the graphical settings in Settings | Windows Update | Advanced Options | Delivery Optimization:

The cmdlets are very straightforward, and you can retrieve the logs and statistics through PowerShell as follows:

#Commands WUDO
Get-Command *deliveryopt*

#Status
Get-DeliveryOptimizationStatus

#Performance Snap
Get-DeliveryOptimizationPerfSnap 

#Performance Snap for current month
Get-DeliveryOptimizationPerfSnapThisMonth

#Get WUDO log
$WUDOlog = Get-DeliveryOptimizationLog 

#Export-CSV
$WUDOlog | Export-Csv c:	empWUDO.log

#Show
$WUDOlog | Out-GridView

#Show Unique Values
$WUDOlog | Select-Object LevelName, Level -Unique
$WUDOlog | Select-Object "Function" -Unique

#Errors
$WUDOlog.Where{$_.Level -eq 2} | Out-GridView
$WUDOlog.Where{$_.LevelName -eq "Error"} | Out-GridView

#Grouping
$WUDOlog | Group-Object -Property Levelname 
$WUDOlog | Group-Object -Property "Function"

In comparison, the graphical user interface in the Settings pane currently looks as follows:

In an enterprise environment, problems with caching and distribution can very easily put a lot of bandwidth in a bottleneck. If you are working with a dedicated proxy to download the updates, and all machines download the updates at the same time, you will easily see your proxy going down. If you plan to work with enabled Delivery Optimization, make sure that it is really working as desired.
