What are all these updates im downloading?

Its becoming almost every weekday that i have to download 100s of MB patches. Im wondering if these are EVE files or are they Vanguard files? Is Vanguard installed by default? How would you get rid of it?

While it doesnt take too long to update the game its annoying having to do it almost every day. Game is less stable than ever btw, im crashing on docking and opening fitting tool quite often now. Plz gib download that fixes the game instead of breaking it more.
