That doesn’t mean though it is not possible, just that it takes a bit more effort. Whatever your reasoning for turning off Windows 10 update you can’t just go to Windows update and turn them off anymore. Peer To Peer also means that you will received files from other users meaning that if, or maybe when ( this is how it could be done, another old example, the latest scare), someone manages to break the security there is a small risk that you could get unwanted files, virus/malware, that way. There also is the risk that the patch is faulty meaning that you cannot wait when a update is released to see if anyone reports an issue. While the updates are set to only run while the computer is idle there still is the risk that an update will download it the wrong moment botching up something important you are working on. There are however also downsides with this. Peer To peer means that you can get parts of files from people closer to you and if you for example have several computers in your local network it should only have to download the updates to one computer and the rest then get the files from that computer. Google has done this with Chrome OS and Chrome for quite a while. Automatic updates will finally maybe make sure your computer illiterate friend or family finally have an updated OS instead of finding them with about 300+ of security patches waiting to download. Both these features does have some good thinking behind them.

Windows 10 brings a host of new changes and among them is the fact that Windows Updates now are mandatory, you cannot turn them off, and that it can take advantage of Peer To Peer functionality.
