System Information Viewer is a small but powerful software that displays information of your computer's hardware and software. It basically gives you access to fully change the Windows behavior, according to your preferences.

Once you have installed the application, it will place itself in the system tray, so you have quick access to all its functions. The main interface of the program is standard - it consists of a single window and a bunch of buttons.

System Information Viewer offers thorough information on your system - Windows, machine, sensors, USB Bus, network, SPD, volumes, Wi-Fi and PCI Bus. So, this tool is designed for power users only.

You can view data about resource usage, processors, volts, temperature, power, memory, CPU and GPU (available and utilized), Cache-0 Latency, and others.

But you can also see what applications and services run at startup, what are your system's base DLL files, what font families you have installed, view a code pages, access the registry editor etc.

Furthermore, you can tune Windows (e.g. disable firewall notifications, override firewall, disable updates alerts) and the system (e.g. disable Task Manager, enable shutdown without logon, set screensaver grace period), and more.

Any information in System Information Viewer can be copied, and you can also access a very extensive help file if you don't understand any of these technical terms.

In our case, the program could not access Windows hotfixes and the clipboard. Also, the dozens of options found here could had been better organized. But System Information Viewer uses a low amount of system memory, it doesn't freeze or crash, and the level of detailed information it offers is extraordinary. We definitely recommend it to hardcore users.
