    Windows delivery optimisation service makes you a part of the Windows update cloud where basically your computer is serving updates to other computers and vice versa. What's bad about it is that there is no way to disable this service from services dialog + it eats away at your bandwidth without your consent as you continuously upload data for other computers. And, it is a security risk because if one machine is offering malicious "update" files by exploiting a vulnerability that Microsoft still doesn't know about or has a patch for, you might end up with a disaster that you never asked for. So, here is how you can disable it for good! I will skip basic steps:

    1: Create a bootable Linux USB (you can use your preferred flavor)
    2: Boot with that USB stick
    3: Access your Windows installation partition
    4: Search for dosvc.dll and delete all instances that you find, including the .mui instances (if any).
    5: Search for domgmt.dll and delete all instances that you find, including the .mui instances (if any).
    6: Reboot machine. Windows Delivery Optimisation is now dead and gone. If you feel that as a result of an update, once again you have this service running, repeat the process.

    Done.

    That’s why on a daily basis, I delete the Windows Update folder so there’s nothing to send out.

    But you can still get updates from other machines that may or may not be secure enough when you update if you have this service running. With this service gone, you get updates directly from Microsoft.

    Even if you tell W10 not to download from other PC’s by turning it off in the update settings?

    MS is quite shady these with these settings as there is no way to disable this service (permissions error in services dialogue) so I prefer removing it the hard way instead of relying on those on/off switches.

    I had a look at the Activity Monitor and it shows 100% download updates (6.6GB) from Microsoft. Uploaded and downloaded data shows 0% and that's after turning off "download from other PC's on the network and internet. What are you seeing on your system?

    That service is a security threat to your computer. Read through my previous posts. Always take things that Microsoft tells you with a grain of salt.
