Disabling Superfetch in windows 7 and 8

You know, when you open task manager, in performance tab, you’ll see a new line than in windows xp, there is “cached memory”.
This is supposedly so when you open the application again, it will be faster, but the side effect is that it eats up your RAM, and disastrous result in low physical RAM since it will drive your free RAM to 0, thus snailing your computer.
So to disable it, it will makes your system lag a bit, but at least your RAM will not be reserved for cache…
There are two steps, first is editing the registry and second is disabling the service.

– Editing the registry:

Even though we doubt it as the source, the windows 7, continue to give pop up warning that windows command processor need to be run, since we already suspect something, we choose no. it happened several times that it started to be annoying.
