Windows 10: Does "Updates from more than one place" work?

Has anyone ever done a bandwidth analysis or comparison that demonstrated that a group of computers updated by sharing update packages instead of downloading complete packages for each computer?

Is there any known command to tell a computer to look for updates on another network computer?

Updates from more than one place (local network) not working

I just checked Disk Cleanup on my front comp and there's only about 3MB in "Delivery Optimization Files". I haven't run Disk Cleanup on that machine in a long time. But I do run CCleaner v5.12 on every bootup to cleanup temp files and junk. But there's no
section in CCleaner about cleaning the DOF location. I checked the temp file's location and it only has the 2 standard temp directories. I wonder where those files are actually stored, and why my system that runs everyday only has 3MB.

EDIT: I did find "\Windows\SoftwareDistribution\DeliveryOptimization". It's empty. The modified date of the folder was yesterday morning at the time I turned on the computer.

 

Updates from more than one place (local network) not working

Noticed once when I ran Disk Cleanup, that "Delivery Optimization Files" showed ~900MB's. This was ~2 weeks ago, for some reason I kept it "checked" and removed the files so now it is down to ~3MB's.

Given it is patch Tuesday, might see if I can catch it working this week....
