Memory History Tool is a free memory monitor for the Windows operating system that provides you with real-time and historic information about a device's memory use.
While desktop memory is cheaper than ever nowadays, considering that you can get 16 Gigabytes of RAM for less than $50, it is still something that is of major concern to many computer users.
Reasons for this are manifold, from running systems with low memory over devices with fixed amounts of memory, to going crazy if half the memory is used up by the operating system even though plenty is still available.
Memory History Tool can be downloaded from the developers website. You can run it right after you have downloaded it from the developer's website as it is a portable application.
It is recommended to run it with administrative privileges as it won't be able to include all processes in the monitoring otherwise. Still, it can be run as a normal user as well.
To do that right-click on the executable file in the root directory of the package, and select run as administrator from the context menu.
Memory History Tools displays the following information in its interface on start:
While the screen is useful in itself, for instance to quickly see if the available memory is sufficient for everyday tasks, it is the program's other features that increase its usefulness.
Memory History Tool keeps track of processes, their memory use and load, while it is running. and displays a list of top processes on demand.
This is quite useful as it provides you with information even if the program is just running in the background and not visible all the time. You may use the menu to open the root folder of the process or the file properties.
One useful option is to run the program for a day or even week, and check the top process listing afterwards to analyze memory use and load on the system.
It can reveal to you if the memory is sufficient, or if the system might benefit from extra memory.
You may open the running process history as well, but it is less useful as it provides no information that the Windows Task Manager supports as well.
Other useful features
You can pause the monitoring at any time without closing the program, and may open csv files which the program creates automatically to access the information in spreadsheet programs such as Excel.
You may export the process list or individual information to csv files on top of that.
Process History Monitor is a handy program if you want to monitor a system's memory use and load over time.
While you may use the Windows Task Manager for that as well, at least partially, it may not be as easy to go through and use, especially since the Task Manager won't reveal the top processes over time.
