Interesting. I didnt know this. I wanted to stop the program from using so much ram because when I play even simple games like CS:GO, it seems to fill up to 3.5 gigs, leaving hardly no room for anything else.
Yes but that's ok because that's exactly what Windows is supposed to do. You have 4gb available so it's going to use it, if you need more RAM for something else then Windows will switch out of RAM what it's not using and load in what it needs on the fly. RAM works in timings down to the nanosecond so by the time you've opened task manager and your eyes have processed the information it's already changed it!
Don't be concerned it's normal behaviour, the time when not enough RAM is an issue is when you notice RAM being constantly 95% + full and significant disk activity when running a program or switching between programs resulting in a slow down of performance. If you check the machine is not running a disk intensive process at the time (like a virus scan) then this is usually the machine having to use the swap file (page file) and swapping basically information it needs out of RAM because it needs to put something else in there. But 4gb of RAM is usually enough for Windows 7 do handle standard office applications, browsing and light gaming. It depends on your machine usage.
