What issues were you having?

So I have two issues that are somewhat annoying and one not so much but a preference. So the two I'll start with is at random not sure why but I'll be browsing and I'll say around 40-80 minutes all of a sudden my memory will jump to around 4,000 and cause massive lag, and its happened on a couple browsers like youtube, facebook and such. The next is I'm supposed to have it to where i left off on my previous tab and when I've closed my browser and tried to go back it doesn't remember and I have to go through history and such to get back which i.snt that big of a issue just annoying. And the one I'm least worried about is the task bar and how much it has changed like refresh location, bookmark tab and just the little things that I'm so used to on the last patch.
