If you want to quickly take a look at what all is there in your computer in terms of hardware, software and other components, here’s a neat trick – type msinfo32 in the start search bar (Run box for Windows XP) and you get a cool System Information Window that shows you all the details!
You get comprehensive information on hardware resources, components and software environment present in your Windows PC.
You can expand the options in the left sidebar and get detailed information on various system parts, the drivers that make them work, manufacturer, version and much more.
Overall, a nice option that can come in handy if you are on phone with a tech support. You could quickly tell him all the details he wants about your system by looking at this window.
