To check the memory on a Windows Vista computer, open the Task Manager. To do this, press Ctrl+Shift+Esc or right-click the taskbar and select “Task Manager.” The Task Manager will show you how much memory is being used by your computer, as well as how much memory is available.
It is important to check your computer’s memory usage regularly to ensure that your computer is running smoothly. If your computer is using too much memory, it can slow down or even crash.
