A power user is a user of computers, software and other electronic devices who uses advanced features of computer hardware, [1] [2] [3] operating systems, [4] programs, or websites [5] which are not used by the average user. A power user might not have extensive technical knowledge of the systems they use [6] but is rather characterized by competence or desire to make the most intensive use of computer programs or systems.
In enterprise software systems, "Power User" may be a formal role given to an individual who is not a programmer but a specialist in business software. Often these people retain their normal user job role but also function in testing, training, and first-tier support of the enterprise software. [6] [7]
Some software applications are regarded as particularly suited for power users and may be designed as such. Examples include VLC media player, a multimedia framework, a player, and a server, which includes complex features not found in other media player suites. [8] [9]

User testing for software often focuses on inexperienced or regular users. [10] Power users can require different user interface elements compared to regular and minimal users, as they may need less help and fewer cues. A power user might use a program full-time, compared to a casual or occasional user. Thus a program which caters to power users will typically include features that make the interface easier for experts to use, even if these features might be mystifying to beginners.
A typical example is extensive keybindings, like Ctrl+F or Alt+Enter; having keyboard bindings and shortcuts for many functions is a hallmark of power-user centric software design, as it enables users who put forth more effort to learn the shortcuts to operate the program quickly without removing their hands from the keyboard.
Power users typically want to operate the software with little interaction, or as fast as possible, and be able to perform tasks in a precise, exactly-reproducible way, whereas casual users may be happy if the program can be intuitively made to do approximately what they wanted. To aid in the automation of repetitive tasks during heavy usage, power-user centric interfaces often provide the ability to compose macros, and program functions may be pre-conceived to with the intention that they will be used programmatically in scripting.
Interface design may have to make trade-offs between confusing beginners and minimalists versus the elaborate needs of experts and power users. These concerns may overlap partially with the blinking twelve problem, in which a complex user interface causes users to avoid certain features. It may be extremely difficult to both appeal to new users, who want user interfaces to be intuitive, and experts, who want power and flexibility.
However, there are solutions for these problems, such as:
Users may also erroneously label themselves as power users when they are less than fully competent, [11] further complicating the requirements of designing software which caters to the desires and needs of those users.
A simple intuitive interface often increases the technical complexity of a program and impedes its efficient use, while a well-designed but complex-seeming interface may increase efficiency by making many advanced features quickly accessible to experts. For example, a program with many advanced keyboard shortcuts may seem to be needlessly complex, but experienced power users may find it easier and quicker to avoid long sequences of mouse clicks to navigate menus and popups. Such menus and popups may exist to intuitively guide new users along a desired course of action, but they are often overly-simplistic by design so that novices might easily grasp the required steps. Providing both interfaces simultaneously is an option but requires greatly extended development time, so trade-offs are often made.
SAP and Oracle are enterprise systems that require a complex set of training to gain professional certification. Because of this, and also to encourage engagement with the systems, many companies have created a "Super User Model" (also called Power User, Champion) to take regular users and raise them to a level of leadership within the system. Doing this accomplishes three objectives: [6] [7]
Extensive research has been done with the Super User Model in SAP, specifically in regard to the role they take in training and supporting end users. Currently, more than 70% of SAP companies utilize a form of the Super User Model.
In Microsoft Windows 2000, Windows XP Professional, and Windows Server 2003, there is a "Power Users" group on the system that gives more permissions than a normal restricted user, but stops short of Administrator permissions. If a user is a member of the Power Users group, they have a greater chance of exposing the system to malware over a normal user and can promote their account to an Administrator by purposely installing malware. [12] Thus, the Power Users group should be used with trustworthy and knowledgeable users only; it is not suitable to contain untrustworthy users. The Power Users group was made obsolete in Windows Vista as part of the consolidation of privilege elevation features in the introduction of User Account Control. [13] In Windows Vista Business l or higher, you can still create a "power user" via local users and groups, but there is no difference from a standard user because all the ACL entries of the file system are completely removed.
Software that power users may employ to optimize their workflows include the following:
A graphical user interface, or GUI, is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.
Microsoft Windows is a product line of proprietary graphical operating systems developed and marketed by Microsoft. It is grouped into families and sub-families that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to third-party hardware manufacturers who sell products bundled with Windows.
In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
In computing, a symbolic link is a file whose purpose is to point to a file or directory by specifying a path thereto.
In computing, an icon is a pictogram or ideogram displayed on a computer screen in order to help the user navigate a computer system. The icon itself is a quickly comprehensible symbol of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the actual entity it represents. It can serve as an electronic hyperlink or file shortcut to access the program or data. The user can activate an icon using a mouse, pointer, finger, or voice commands. Their placement on the screen, also in relation to other icons, may provide further information to the user about their usage. In activating an icon, the user can move directly into and out of the identified function without knowing anything further about the location or requirements of the file or code.
Computer accessibility refers to the accessibility of a computer system to all people, regardless of disability type or severity of impairment. The term accessibility is most often used in reference to specialized hardware or software, or a combination of both, designed to enable the use of a computer by a person with a disability or impairment.
In computing, a keyboard shortcut is a software-based assignment of an action to one or more keys on a computer keyboard. Most operating systems and applications come with a default set of keyboard shortcuts, some of which may be modified by the user in the settings.
The taskbar is a graphical user interface element that has been part of Microsoft Windows since Windows 95, displaying and facilitating switching between running programs. The taskbar and the associated Start Menu were created and named in 1993 by Daniel Oran, a program manager at Microsoft who had previously collaborated on great ape language research with the behavioral psychologist B.F. Skinner at Harvard.
In computing, text-based user interfaces (TUI), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent of bitmapped displays and modern conventional graphical user interfaces (GUIs). Like modern GUIs, they can use the entire screen area and may accept mouse and other inputs. They may also use color and often structure the display using box-drawing characters such as ┌ and ╣. The modern context of use is usually a terminal emulator.
In human–computer interaction, WIMP stands for "windows, icons, menus, pointer", denoting a style of interaction using these elements of the user interface. Other expansions are sometimes used, such as substituting "mouse" and "mice" for menus, or "pull-down menu" and "pointing" for pointer.
A software wizard or setup assistant or multi-step form is a user interface that leads a user through a sequence of small steps, like a dialog box to configure a program for the first time. They are used to make complex, unfamiliar tasks easier by breaking them into smaller pieces.
Job Access With Speech (JAWS) is a computer screen reader program for Microsoft Windows that allows blind and visually impaired users to read the screen either with a text-to-speech output or by a refreshable Braille display. JAWS is produced by the Blind and Low Vision Group of Freedom Scientific.
The Start menu is a graphical user interface element that has been part of Microsoft Windows since Windows 95, providing a means of opening programs and performing other functions in the Windows shell. The Start menu, and the Taskbar on which it appears, were created and named in 1993 by Daniel Oran, a program manager at Microsoft who had previously collaborated on great ape language research with the behavioral psychologist B.F. Skinner at Harvard.
A voice-user interface (VUI) enables spoken human interaction with computers, using speech recognition to understand spoken commands and answer questions, and typically text to speech to play a reply. A voice command device is a device controlled with a voice user interface.
The Windows shell is the graphical user interface for the Microsoft Windows operating system. Its readily identifiable elements consist of the desktop, the taskbar, the Start menu, the task switcher and the AutoPlay feature. On some versions of Windows, it also includes Flip 3D and the charms. In Windows 10, the Windows Shell Experience Host interface drives visuals like the Start Menu, Action Center, Taskbar, and Task View/Timeline. However, the Windows shell also implements a shell namespace that enables computer programs running on Windows to access the computer's resources via the hierarchy of shell objects. "Desktop" is the top object of the hierarchy; below it there are a number of files and folders stored on the disk, as well as a number of special folders whose contents are either virtual or dynamically created. Recycle Bin, Libraries, Control Panel, This PC and Network are examples of such shell objects.
In computing, a keyboard shortcut is a sequence or combination of keystrokes on a computer keyboard which invokes commands in software.
In computer interface design, a ribbon is a graphical control element in the form of a set of toolbars placed on several tabs. The typical structure of a ribbon includes large, tabbed toolbars, filled with graphical buttons and other graphical control elements, grouped by functionality. Such ribbons use tabs to expose different sets of controls, eliminating the need for numerous parallel toolbars. Contextual tabs are tabs that appear only when the user needs them. For instance, in a word processor, an image-related tab may appear when the user selects an image in a document, allowing the user to interact with that image.
A user is a person who utilizes a computer or network service. A user often has a user account and is identified to the system by a username . Some software products provide services to other systems and have no direct end users.
In user interface design and software design, the principle of least astonishment (POLA), also known as principle of least surprise, proposes that a component of a system should behave in a way that most users will expect it to behave, and therefore not astonish or surprise users. The following is a corollary of the principle: "If a necessary feature has a high astonishment factor, it may be necessary to redesign the feature."
Comparison of user features of operating systems refers to a comparison of the general user features of major operating systems in a narrative format. It does not encompass a full exhaustive comparison or description of all technical details of all operating systems. It is a comparison of basic roles and the most prominent features. It also includes the most important features of the operating system's origins, historical development, and role.
