System Information

'System Information' (also known as msinfo32.exe) shows details about your computer's hardware configuration, computer components, and software, including drivers.

System Information.

You can get to 'System Information' by clicking 'Start', and typing 'System Information' or 'msinfo32.exe' into the search box, and then pressing 'Enter' on the keyboard.

When you open 'System Information' you will see details including the Operating System & version, CPU, and the amount of system memory (RAM) on your computer.

You will also see the following:

Hardware Resources:
This will detail your hardware and what resources they use such as memory and IRQs, and lists which hardware shares these.

An IRQ is an Interrupt Request which allows a hardware device to interrupt the processor (CPU) to handle certain events. For instance, when you press a key on your keyboard it sends an Interrupt Request to the processor so that the CPU will see which key was pressed and will take the appropriate action. In this way you are able to do several tasks on the computer seemingly at the same time, such as moving the mouse, using the keyboard, sending output to the screen, and reading or writing data etc. There are different levels of IRQ which determine their priority.

This shows details of your hardware components. For example if we select 'Display' then it will show the name of your Graphics Card along with how much GDDR memory it has, and the installed device driver and version. It will also show the current display resolution as well as other useful information.

It also details information on your Drives such as the name, drive letter, size of the disk and how much space remains, and file system used.

Software Environment:
This will display all the 'startup programs', 'services', current 'running tasks', 'print jobs, currently running, 'system drivers', and 'network connections' etc.
