I don’t know about you, but I’m sick and tired of reading these sensational headlines: “Windows 10 is Stealing Your Bandwidth! While I agree that Microsoft may be a bit misguided in how it has implemented privacy settings in Windows 10 thus far, we can discuss Windows Update Delivery Optimization intelligently, reasonably, and without fearmongering. By the end of this article, you’ll understand a thing or two about Windows Update Delivery Optimization (WUDO), how to control its behavior, and what you can do to minimize the likelihood of running over your ISP account’s bandwidth limit.

In some ways, WUDO is similar to the Branch Cache Distributed Cache Mode we already have in Windows Server and Windows Client OSs.

The first common complaint with WUDO is that the feature is enabled by default in all editions of Windows 10.

Depending on the Windows 10 edition, WUDO functions in one of two modes: Ouch!

I agree that opening up my private Windows 10 machines to receive Windows updates from random Internet hosts disturbs me a bit.

Microsoft explains in its literature that cached updates are encrypted, verified, and authenticated to ensure that only original, non-tampered bits make their way from a stranger’s PC to yours.

Nevertheless, you probably want to learn how to override the defaults.Meanwhile, the second popular WUDO criticism is that computers with metered Internet connections may consume more bandwidth than the owner expected due to the background participation in WUDO peer-to-peer updates.As of this writing in October 2015, WUDO and deferred updates are the only Windows Update for Business features that are surfaced in Windows 10.We’re expecting additional features and functionality in November’s “Threshold 2” update—we’ll have to wait and see on that.Specifically, WUDO allows businesses to save Internet bandwidth by using a peer-to-peer model for delivering Windows updates.The idea is that one Windows 10 box actually downloads the updates, either directly from Microsoft or from a local WSUS server, and then serves the bits with other Windows 10 clients on the same network.
