Windows RT vs. Windows 8: Understanding the Differences

Understanding Windows RT: A Distinct Edition of Windows 8
Windows RT represents a unique version of the Windows 8 operating system. It is specifically designed to function on ARM processors.
You can locate devices powered by Windows RT alongside those utilizing Intel x86 processors in retail environments.
Key Differences from Traditional Windows
Despite sharing a similar name, Windows RT exhibits substantial differences compared to the standard Windows experience.
These distinctions are significant enough that Microsoft has communicated to Mozilla that Windows RT should not be considered the same as conventional Windows.
Importance of Differentiation for Consumers
When considering a purchase of a Windows-based system, it’s crucial to understand the distinction between Windows RT and other iterations of Windows 8.
Being aware of these differences will help ensure you select a device that aligns with your specific needs and expectations.

ARM vs. x86
During its development phase, Windows RT was internally referred to as Windows on ARM, abbreviated as WOA. This represents a fundamental adaptation of the Windows operating system, transitioning it from the Intel x86 processor architecture to the ARM processor architecture.
Currently, x86 processors are prevalent in conventional laptops and desktop computers. Conversely, the majority of smartphones and tablet devices utilize ARM processors for their operations.
As a result of being a ported version of Windows designed for a distinct architecture, it lacks compatibility with older, legacy software. This means programs originally created for the standard Windows environment are not directly supported.
The designation “Windows RT” arose because it exclusively supports applications developed for the Windows Runtime, or WinRT. It’s important to note that “WinRT” describes the runtime environment functional across both architectures, while “Windows RT” specifically identifies the operating system limited to ARM processors.
These Windows Runtime applications were commonly recognized as “Metro apps” by users.

A Desktop Environment Exists, Yet…

Windows RT incorporates a desktop interface, mirroring those found in other Windows 8 versions. Access to the desktop allows utilization of traditional Microsoft applications, including the Control Panel, Windows Explorer, and Internet Explorer. Furthermore, each Windows RT device is pre-loaded with touch-optimized Microsoft Office applications for desktop use.
However, a key limitation exists: Windows RT desktops cannot execute applications from developers other than Microsoft. It’s a common misconception that these applications are simply not yet compiled for the ARM processor. But Microsoft actively prevents the installation of third-party desktop applications on Windows RT.
Essentially, the Windows RT desktop is a restricted environment, exclusively designed for Microsoft-developed software. Installing desktop applications not created by Microsoft is not possible.
While Windows Media Player is a common component of the Windows experience, it is not included with Windows RT.
Limitations on Third-Party Software for Windows RT
Within the Windows RT operating system, all applications originating from third-party developers are required to adhere to the Metro application standard. These Metro applications must undergo a review and approval process through the Windows Store, overseen by Microsoft.
Consequently, Windows RT devices are restricted to executing only those applications that have received Microsoft’s authorization. This parallels the application ecosystem of Apple’s iPad, which similarly limits users to Apple-approved software.
This restriction extends to the selection of web browsers. On Windows RT, the Metro edition of Internet Explorer possesses exclusive access to the device’s system Application Programming Interfaces (APIs).
This exclusive access prevents developers from companies like Mozilla and Google from creating native browsers specifically for Windows RT. Both Mozilla and Google have voiced their concerns regarding this limitation.
Users of Windows RT devices will, therefore, be reliant on Internet Explorer for their browsing needs. This situation mirrors the iPad experience, where Safari is the primary browser option.
Any third-party browser available for the iPad functions as an interface built upon Safari’s core functionality. Similarly, all alternative browsers intended for Windows RT will operate as wrappers around Internet Explorer.

Windows RT: A Device-Focused Operating System
The design of Windows RT is demonstrably influenced by the iPad, and the similarities in restrictions are intentional. Microsoft conceptualizes Windows RT-powered machines as “devices” rather than conventional personal computers.
A retail purchase of Windows RT as a standalone product will not be possible; it will exclusively be offered pre-installed on systems utilizing ARM processors. Initially, these ARM-based systems will primarily consist of Windows tablets.
However, there’s no inherent limitation preventing Windows RT from being deployed on laptops and even desktop computers equipped with ARM chipsets in the future.
Restrictions and Secure Boot
Further limitations will be imposed on Windows RT devices. Microsoft requires that Secure Boot functionality on these devices remains non-configurable by the user.
This means users will be unable to replace Windows RT with alternative operating systems like Linux or others.

- Windows RT is designed for ARM-based devices.
- It is not available for purchase separately, only pre-installed.
- Secure Boot cannot be altered by the user.
The intention is to create a more controlled ecosystem, similar to that of Apple’s iOS. This approach prioritizes security and stability by limiting user modifications to the core operating system.
Limitations for Business Users
Windows RT presented several shortcomings regarding features crucial for enterprise environments, which historically contributed to the widespread adoption of traditional Windows. Specifically, Windows RT-based devices were unable to integrate with Active Directory or function within a domain.
This lack of compatibility also extended to the absence of Group Policy support, hindering centralized management through established Windows infrastructure.
Further Feature Deficiencies
Beyond domain integration, Windows RT omitted a range of functionalities considered standard in professional settings. These included technologies like Storage Spaces for flexible data management.
Furthermore, features such as BitLocker drive encryption, remote desktop hosting capabilities, and encrypted file systems were not available on Windows RT devices.
A comprehensive overview of these limitations can be found in Microsoft’s official announcement detailing the various Windows 8 editions.
Distinguishing Windows Tablets: Not All Utilize Windows RT
A significant portion of Windows tablets, particularly those readily available at retail upon the launch of Windows 8, are not powered by Windows RT. Instead, these devices employ conventional x86 Intel processors and operate with a standard edition of Windows 8.
This configuration ensures compatibility with third-party desktop applications and the full spectrum of Windows functionalities.
For users prioritizing support for existing desktop software, selecting a tablet with an x86 processor is crucial, as opposed to an ARM-based device.
Furthermore, those seeking robust enterprise-level features should generally avoid Windows RT options.
Cost Considerations for Windows RT
Recent reports suggest that the licensing cost for Windows RT is anticipated to be approximately $85 per unit for manufacturers.
This pricing structure positions Windows RT as a more expensive operating system compared to other Windows 8 versions.
Consequently, Windows RT tablets are projected to have a higher price point than iPads.
It is even plausible that these tablets will exceed the cost of more comprehensively equipped Windows 8 tablets featuring x86 processors.
- Key takeaway: Windows RT tablets may be pricier than both iPads and full Windows 8 tablets.
Understanding these distinctions is vital when choosing a Windows tablet to ensure it aligns with your specific needs and budget.
