Why buy ram when you can download it?
Guys, let me tell you a tip. Microsoft knows that they can't make enough money off of Windows and Xbox alone, so they planted in System 32, which literally takes up up to 32 GB of RAM at a time. Microsoft also owns several RAM downloading sites, including Download More RAM. They know that if they implanted a program to consume RAM, they can get shitloads of money just off the RAM purchases. But I don't like their way of taking our computer's hostage, so that's why I'm going to tell you a tip.
In order to free up your RAM again, you have to delete System 32 as it's the program that is taking up all your RAM. To do this, you have to open up "Computer" or "My Computer" from the Start Menu or Metro or whatever you have. Then you have to search for "system 32" in the search bar in the corner. Just wait for everything to load and then delete all of that. Just remember to delete it all at once, not bit by bit, or it'll try to install the missing files again, which takes up even more RAM.
