Monitoring the bandwidth usage of a computer system can be beneficial in several ways. You can use the data to make sure you stay under a monthly limit, which may be very helpful if you are on a limited plan that is only providing you with a set amount of free traffic per month. A bandwidth monitor furthermore can also be helpful when you are auditing your PC, for instance to find out which programs and services go online.
Cucusoft Net Guard is a free program for the Windows operating system. You can download it freely from the developer website but need to enter an email address during first run to receive a serial number that you need to enter to use the program at all.
Once that is out of the way you will notice the small upload and download realtime widget that is added just above the Windows system tray area. A click on the widget expands it displaying statistics about the day's Internet usage. This includes the overall bandwidth used, the upload and download bandwidth, and the programs that top the upload and download bandwidth statistics for that day.
Note: Pay attention to Netguard's installation dialog, as you may find third-party offers included in it that are not necessary for the program's core functionality. If you do not want those installed, make sure you select decline or skip to do so.
You can hide the floating window and only use the main application window instead which you can open from the operating system's system tray area.
Here you can access information in the following five tabs:
If you are interested in the monitoring aspect only, then Net Guard is an excellent program for that job. It's memory is definitely on the high side though and alternatives like Netmeter or Open Monitor may be more suitable for low-memory systems.
If you want to control the upload and download speed of a process as well, then you should take a look at NetBalancer Free instead which can do exactly that.
