Have your Windows 10 computer running slowly? Maybe it’s time to upgrade the memory or add a new memory if the slot is still available. But first, you need to make sure if the cause that makes your computer running slowly is really the memory.
There are several ways to check the memory usage in Windows 10. The easiest way to check the memory usage in Windows 10 (and other Windows versions) is via Task Manager. Task Manager allows you to check the memory usage of each running app as well as the available memory. To get started, open Task Manager and make sure to expand its window by clicking More details on the bottom side of the Task Manager window.

Once the window expanded, you can see the memory usage of each running app on the Memory column under the Processes tab. You can also see the overall usage (percentage) of the memory on the column header.

If you want to see the more human-readable numbers, you can go to the Performance tab and click the Memory label on the left panel. From here, you can see the exact number of the available memory as well as the RAM speed and available slots.

In addition to Task Manager, you can also check the memory usage on your Windows 10 computer using another built-in tool of Windows, Resource Monitor. To open the Resource Monitor window, you can type rsmon
on the Run dialog box. You can check the memory usage by clicking the Memory tab on the Resource Monitor window.

You can see stats of the memory usage on the bottom side. Resource Monitor also allows you to monitor the memory usage in real-time via the monitoring tool available on the right side. If you use a system-cleaning tool like CCleaner, you might also check the memory usage from within the app window.
