The feature, known as Windows Update Delivery Optimization (WUDO), is initially designed to help users get faster software updates,
which is quite a good idea to handle massive internet traffic of up to 40 Terabits per second (TBps).

WUDO works a lot like torrents work. Your computer running Windows 10 is used as part of a peer-to-peer network to deliver
software updates faster to others, each person distributing a little bit of the files across multiple computers and helping everyone
download updates quickly.

But, this peer-to-peer sharing method offered by Windows 10 is using your precious Internet bandwidth, without hinting you about it,
because the feature is enabled by default in Windows 10 Home and Pro edition.

WUDO is also enabled in Windows 10 Enterprise and Education, but only for the local network.



How to Disable Windows Update Delivery Optimization (WUDO)?

You can disable the feature, but the option is buried deep in the Settings menu for Windows Update.

To turn this feature OFF, follow these given steps:

Go to Settings in the Start menu
Search for Update & Security
Under Windows Update, open Advanced Options
Under Choose How Updates are Installed, select Choose how updates are delivered
Disable the toggle under Updated from More than One Place

That is a very good reason why it should be turned OFF. The default should not be ON.

I am glad my tip is working out OK for some people on Windows 10.
