PCI-Z is a simple information application that displays details of installed PCI family expansion cards and other components of the motherboard (including newly installed ones that have not yet been recognized). In practice this includes PCI Express and PCI-X cards, motherboard controllers (sound cards, network cards, SATA interfaces, etc.). Additionally, the program displays basic data about the computer:

its name, currently logged in user, installed processor, amount of available memory and version of the operating system. The data displayed includes the name of the manufacturer of the equipment, specific device symbols, type and subcategory, and status. It will tell you, first of all, whether the devices have been properly configured and whether you need to install newer drivers.

If so, we can search them directly from the application using the options in the context menu, but in practice it consists in automatically generating a query to Google search engine and displaying a list of all the results in the default browser. The final selection of the appropriate driver, as well as its download and installation, will therefore be at the user's discretion. A convenient addition may be the option to export data in the form of a report (in TXT, CSV or JSON format) and the ability to send a report by e-mail, although in this case, the configuration of the account from which the message will be sent was unnecessarily complicated to several steps in separate windows.

For this reason, although it is a simple activity, in practice it seems to be too time-consuming.
