If you don't have it yet, go to Windows Update and click on the "Learn More" link. I just did, and it took about an hour and 15 minutes to download and install.
I use two computers, one a laptop and the other a desktop that I rescued from my son and fixed somehow or other (I didn't write down what I did and don't remember specifics. I was trying to fix an overheating problem and I did.) The laptop, a Lenovo Z710, had a rough time downloading the Anniversary update and installing it. Took over 3 hours. The laptop did have the update available on the 2nd and I just did what I always do with an update. I actually gave up on the update and just let the laptop sit while I ran out for some errands. It was up and running correctly when I got home.
While I was working on the laptop update I ran downstairs and checked the desktop and it didn't have an available update. That morning I had received an email from one of the web sites that detailed how to hit that "Learn More" link and I did that. The desktop downloaded the update and installed it in an hour and a half. Pretty big difference in the two downloads. When I left the house I was of the opinion that the update had destroyed the laptop and I was working myself up to buy a new laptop. Don't need to do that, the laptop is running just as well as it always has.
I guess I did the "rescue" of the desktop properly...
