Diablo – Playing Diablo 3 Hardcore with Windows 10 Automatic Update

diablo-3windows 10

I almost exclusively play hardcore mode, and I much prefer it. The only downside, as I see it, is that lagging out or disconnecting may kill you (I'm fine with any other kind of death).

Now, I recently updated to Windows 10, and with that comes the fact that you cannot disable automatic updates. Now, I could totally see a situation where a download suddenly starts and causes me to lag in-game. This could apply to other online games as well.

Is there anything built into Windows 10 that prevents this from happening with online games? I could imagine they would want to disrupt the user experience as little as possible. If no, is this something I should realistically worry about, and what (if anything) can be done about it?

(I'm not interested in answers suggesting switching from Windows 10)

Edit: As said in comments, online games have different needs from other types of media, such as being more dependent on latency than bandwidth. This question was specifically intended to ask how gaming is affected by the changes presented in Windows 10, and for this particular question I'm only interested in facts about the operating system as a gaming platform, and how it directly affects my gaming experience.

Honestly, Windows Update shouldn't lag your game, unless your internet connection is slow. I have a 256kB/s connection, and it doesn't seem to have any effect while playing games online.
If at all, Windows Update tries not to affect the speed of your any other connections to the internet while it's updating.

If you're really worried about Windows Update lagging up your system by downloading updates in the background, you can disable it by disabling the wuaserv service.

Note: You cannot disable it through the Control Panel or Settings App. The only way to do it is to go "under the hood".
