How to Increase RAM ?
First of all open any application say MS word file then go to Task manager by pressing Ctrl + Alt + Del. you will see the Word.exe at the near about top of the list in the process tap.Now close it and minimize the world file, don't minimize other application. Now check the memory from task manager process tab which word.exe is using. Surprised? Now it is using less RAM.
So if you will minimize the application it will consume less RAM.
