option is selected within the lower pane of the System Policy Editor (see the discussion of PART and the code example below).

If not specified otherwise, the value will be written in the following format when any administratory checks or unchecks the option:

Checked: REG_DWORD with a value of 1

Unchecked: Removes the value completely

Other options can specify what the user selects from and what gets written to the registry.

Use the keyword PART to specify options, drop-down list boxes, text boxes, and text in the lower pane of the System Policy Editor. PART is similar to CATEGORY, and uses the syntax:

PART !!MyVariable FLAG

...

END PART

where FLAG is one or more of the following:

TEXT— Displays text only, for example:

PART !!MyPolicy TEXT END PART

NUMERIC— Writes the value to the registry with data type REG_DWORD, for example:

PART !!MyPolicy NUMERIC VALUENAME ValueToBeChanged

END PART

DROPDOWNLIST— Displays a list box of options to choose from, for example:

PART !!MyPolicy DROPDOWNLIST VALUENAME ValueToBeChanged

ITEMLIST

NAME “First” VALUE NUMERIC 1 NAME “Second” VALUE NUMERIC 2 NAME “Third” VALUE NUMERIC 3 NAME “Fourth” VALUE NUMERIC 4 END ITEMLIST

END PART

EDITTEXT— Writes the value to the registry with data type REG_SZ, for example:

PART !!MyPolicy EDITTEXT VALUENAME ValueToBeChanged

END PART

REQUIRED— Generates an error if the user does not enter a value, for example:

PART !!MyPolicy EDITTEXT REQUIRED VALUENAME ValueToBeChanged

END PART

EXPANDABLETEXT— Writes the value to the registry with data

Windows NT 4.0 specifications

Microsoft Windows NT 4.0, released on July 29, 1996, marked a significant milestone in the evolution of Microsoft's operating systems. As the successor to Windows NT 3.51, this version brought a range of enhancements and features that appealed to both enterprise users and consumers.

One of the standout characteristics of Windows NT 4.0 was its introduction of the Windows 95 user interface, which significantly improved user experience and accessibility. This graphical interface made it easier for users to navigate the operating system, transitioning from the more complex interfaces of previous NT versions. The integration of familiar elements such as the Start menu and taskbar helped bridge the gap between professional and personal computing environments.

Windows NT 4.0 was built on a robust and secure architecture. It utilized the NT kernel, which provided improved multitasking and stability compared to its predecessors. This operating system was designed to handle multiple user sessions simultaneously, making it suitable for servers as well as workstations. The inherent stability of NT 4.0 made it a favorite in enterprise environments, particularly for critical applications and systems.

Another defining feature of NT 4.0 was its support for a wide range of hardware, making it versatile across various machine configurations. It included compatibility with numerous devices and peripherals, which facilitated its adoption in diverse settings.

In addition to user interface enhancements and hardware compatibility, Windows NT 4.0 introduced powerful networking capabilities. The operating system supported TCP/IP natively, alongside NetBEUI and IPX/SPX protocols. This meant that it could seamlessly integrate into existing network environments, providing essential services for file and printer sharing, domain management, and remote access through features like Remote Access Service (RAS).

Security was another key focus area for Windows NT 4.0. Built around security principles, it employed a discretionary access control system, allowing administrators to define user permissions and manage access to resources effectively. This was particularly appealing to businesses that needed to enforce strict security policies.

Windows NT 4.0 also included improved support for backup and recovery, through the inclusion of the NT Backup utility. The operating system allowed for the creation of scheduled backups and simplified data recovery processes, enhancing data integrity and reliability.

As NT 4.0 entered its later years, it laid the groundwork for future Windows operating systems, influencing the design of later versions, particularly Windows 2000. It combined user-friendly features with enterprise-level robustness, ultimately shaping expectations for modern operating systems across various industries.
