HWiNFO is a system summary tool that displays all information about your computer- from the CPU temperatures to fan voltages. This is not just a program that can monitor your system performance or temperature, but it also includes a user-friendly interface that allows you to customize different settings for your system profiles.

You will also be able to see if there are problems related to cooling by reading values like Delta T (temperature difference) and RPM (fan speed). This application does not come free of charge; however, for the features and many customization options it offers, we think that it’s completely worth its price.

Performance Monitor

Performance Monitor is a powerful tool that administrators can use to examine how programs running on their computers affect the computer’s performance. It can be used in real-time and also be used to collect information in a log to analyze the data at a later time.

It captures different types of system data, including CPU utilization, memory utilization, disk I/O activity, network activity, process information, and power state transitions.

Administrators may find this useful for troubleshooting purposes as it provides detailed insight into what is happening with their computers such as which applications are using up most of the resources or draining the battery quickly.

The administrator may then take action by shutting down unneeded services or processes if they’re causing problems or simply decide not to install those particular programs to reduce how much resources they take up and to avoid future problems.

Performance Monitor is a built-in tool found in Windows operating systems and can be accessed by going to Start > Run, typing “Perfmon” (without quotations), and hitting Enter on your keyboard.

Reliability Monitor

The Reliability Monitor is a tool to investigate crashes and errors on your PC. Although it has been around since Windows Vista, Microsoft has continued to improve the program and add more features. It’s a good idea to run this diagnostic tool once in a while to keep an eye on things and fix potential issues that may be present within your computer.

It can find in the Control Panel > System & Security > Security & Maintenance > Maintenance > View reliability history.

The Reliability Monitor will show potential causes for these errors and give you step-by-step instructions on how to fix them which should avoid future problems from occurring again in the future.

WiFi Analyzer

WiFi Analyzer is a software suite for Windows that enables users to analyze the wireless environment.

It collects information about nearby access points and displays them in a number of graphical formats on the screen, including charts showing signal strength over time, maps of access point locations with signal strength overlaid, and heatmaps depicting areas where there are many or few access points.

It also generates reports listing all detected networks and their properties (such as SSID) which can be saved for offline viewing. WiFi Analyzer is available as both an app for Android devices running 4.3 or higher, and an application for Mac OSX 10.8 or higher running on Intel processors only; it requires administrator privileges to run on either platform because it needs to install a kernel-mode device driver in the operating system. It is free, open-source software released under the GPLv2 license.


CrystalDiskInfo is a free, open-source program that provides information about the hard disks installed on your computer. It supports SSDs and HDDs of any size, including ATA/ATAPI (PATA), SATA, SCSI, and USB drives. The interface presents an overview of the disk’s health with separate tabs for SMART status, temperature, and drive security features. To access more detailed information simply click on the tab you’re interested in. A good way to use this tool is to periodically check it while running other programs – if you notice unusual behavior or some kind of warning message then it might be time to take steps before things get worse.
