The Windows 10 operating system has a new feature called “Windows Update Delivery Optimization” (or “WUDO”). This feature allows a lot of people to download very big files at once. However, it can also hinder the performance of your internet connection. WUDO works a lot like bit torrents in that it allows other computers from around the world to download a little bit of the update code from your computer. While this peer to peer network may help to deliver updates to others faster, it is using your bandwidth to do it. This is not a problem if you are not using your bandwidth at the time, but if you need the internet while others are downloading Windows 10 or Windows 10 updates that creates a problem.
This sharing method uses your Internet without telling you because it’s automatically enabled in Windows 10 Home, Pro, Enterprise, and Education editions. If you are using Windows 10 and have slow Internet, we recommend you turn off this “WUDO” feature. The following links have step-by-step instructions to disable the feature.
BTW, every time you download an update you may need to turn WUDO off again. If you need additional help, please let us know.
