Which w10 build are you on? if things are freezing I think you should consider doing a refresh (settings > update > recovery > refresh and keep files)
If internet speed is your main issue, try a program like netbalancer..
If all of that fails, there is a way to turn off windows updates, but it isn't recommended or you should at least turn it back on every other day or night so that the necessary updates can download... Try the other solution first tho
