Microsoft's Windows 95 was the first operating system to make use of wizards. The most commonly-used wizard at the time was the Internet Connection Wizard, which was renamed to the "New Connection Wizard" in later versions of Microsoft Windows. This wizard guides the user through the process of creating a connection to the Internet, or to a Virtual Private Network. Wizards had become commonplace in most consumer-oriented operating systems. In Mac OS X, for example, they are called "Assistants"; some examples include the "Setup Assistant", which is run when one boots the Macintosh for the first time, and the "Network Setup Assistant", which has similar function to the aforementioned "New Connection Wizard".

Web applications, such as an airline booking site, also make use of the wizard paradigm to complete lengthy interactive processes.

By contrast, expert systems guide the user through a series of (usually yes/no) questions to solve a problem, and tend to make use of artificial intelligence or other complex algorithms. Some consider expert systems as a general category that includes all problem-solving programs including wizards.

Wizards were controversial among user interface designers when they first gained widespread use, because they encourage modal windows, which some consider antithetical to proper human interface design. Supporters of the wizard paradigm argue that compliance with what they consider to be arbitrary laws should be secondary to ease of use in interface design.

Quality Process Automation

Karomi ENTERPRISE: Although not widely available today, service-oriented architectures are an umbrella term for a move in IT systems towards providing greater Quality Process Automation access and exchange of functionality between systems. The idea is that both previous and future IT systems will be re-engineered to provide standard interfaces, thus allowing themselves to be linked more easily and flexibly. However as these standard interfaces can only be delivered relatively slowly, it will be some time before SOA can be viewed as an immediate option for delivery of process automation.
