Windows 10 Update Management

since the last two weeks I have been trying to update my windows 10(a 3gb file). But this update interface of windows settings is so unstable that every time the wi-fi disconnects for a second its cancels the whole download and I have to restart it from the beginning. They should have made it like a download manager where we can pause and resume the downloading of such huge sized files. It's been a very annoying experience. I tried downloading it from the browser but its unavailable there too. Despite of my urge to download the update I am unable to do so.
