I've just installed the latest Windows 10 updates, and rebooted, and the RAM usage is extremely low. On my 6GB laptop, memory usage is sitting at just 46% with 42 tabs open in Chrome. Actually, I'm using 360 Extreme Explorer, but it by default it renders just about all pages with Chrome. This is really impressive considering I have two antiviruses, and hundreds of programs installed. For example, there are 17 icons in the system tray, and around 30 third party services running.
