All the lagging and refusing to work, is why I disabled automatic updates. It still ticks me off when I am in the middle of something, and it starts looking for updates. Or, when it decides to disconnect from my Wi-Fi.
It was worse before I switched internet providers. Imagine trying to do anything with 0.1 Mbps! I'm sure I'd get reported if I mentioned which company screwed me over like that. I used to get 10 Mbps from that company, but they decided to make all their customers pay a much higher price for that internet speed, calling it an "upgrade". Now, that really made me cuss and yell.
