Constant updates?

I just hate it how everything always wants to update… and then restart all the damn time!

First things first:

This pops up telling me it’s doing a 309.6MB Adobe Reader Update! Which to me is just crazy… Surely the constant updates shouldn’t be a million times larger than the actual initial install file for the application?

I just click Cancel and then do this..

Not a minute later and this little guy pops up!
Will it ever end????
