Question: What is the modern equivalent of Windows NT Workstation?
The modern equivalent of Windows NT Workstation is Windows 10 Pro.
Windows NT Workstation was a version of Windows NT that was designed for use on individual workstations, rather than server environments. It was released in 1993 and was succeeded by several other versions of Windows, including Windows 2000 Professional, Windows XP Professional, Windows Vista Business/Ultimate, Windows 7 Professional/Ultimate, Windows 8 Pro, and finally Windows 10 Pro.
Windows 10 Pro includes many of the features that were available in Windows NT Workstation, such as advanced networking capabilities, support for domain join, and remote desktop access. However, it also includes many new features and enhancements that were not available in earlier versions of Windows, such as improved security, virtual desktops, and the Windows Subsystem for Linux.

How to upgrade clients running Windows NT Workstation 3.51 or 4.0 when running Windows legacy operating systems..
Because Windows NT Workstation 3.51, Windows NT Workstation 4.0, and Windows 2000 Professional share common registry, file system, security, and operating system kernel structures, nearly all applications that run on Windows NT Workstation 4.0 will run without modification on Windows 2000 Professional. In addition, upgrading from Windows NT Workstation to Windows 2000 Professional is easier than upgrading from other Windows operating systems for of the following reasons:

1. Almost all peripherals and devices that work with Windows NT Workstation 4.0 will work with Windows 2000 Professional.
2. The version of NTFS used in Windows NT Workstation 4.0 is transparently upgraded to the version of NTFS used in Windows 2000 Professional during the upgrade process.

There are some differences between the version of NTFS used by Windows NT 4.0 operating systems (NTFS 4) and Windows 2000 operating systems (NTFS 5). This may prevent some of the programs you have used in Windows NT 4.0 from working properly in Windows 2000.
For example, anti-virus programs that work in Windows NT 4.0 may not be able to handle "reparse points" that they might encounter if you have created Volume Mount Points. This incompatibility may not be reported by the Upgrade Evaluation tool.

The Windows 2000 Setup Wizard generates a compatibility report similar to the reports that are generated on client computers running Windows2000 and Windows 98. This report is automatically saved in the systemroot folder in a file called Winnt32.log, as shown below.

To upgrade clients running Windows NT Workstation 3.51. or 4.0 to Windows 2000, follow the steps shown the following simulation:

Windows Server 2008 R2, codenamed "Windows Server 7", is the fifth-generation operating system produced by Microsoft for servers. It belongs to the Windows NT family of operating systems and was released on July 22, 2009, becoming generally available on October 22, 2009, shortly after the completion of Windows 7. As a successor to Windows Server 2008, this server operating system is derived from the Windows Vista codebase and was later superseded by Windows Server 2012, which is based on Windows 8.

Windows Server 2008 R2 comes with new and enhanced features to deliver an improved experience to enterprises. The new functionalities include advanced features for Active Directory, management features for virtualization, and support for up to 256 logical processors. Additionally, the version 7.5 of the Internet Information Services web server is a part of this server operating system.

Windows Server 2008 R2 is built on the same kernel as Windows 7, the client-oriented operating system from Microsoft. However, it is the first server operating system released by Microsoft not to support 32-bit processors, marking a shift to more advanced hardware.

Windows Server 2008 R2 marked a significant milestone for Microsoft as it introduced new functionalities for virtualization and Active Directory. It was the most comprehensive server operating system available for enterprises, offering advanced features to support their needs. Although it has been superseded by newer versions of Windows Server, Windows Server 2008 R2 continues to be a widely used server operating system globally.

In Windows Server 2008, Microsoft delivers a server operating system that is something more than the sum of its parts. Windows Server 2008 isn’t just a server operating system or a network operating system. It is a best-of-class operating system with the foundation technologies necessary to provide networking, application, and online services that can be used anywhere within your organization. From top to bottom, Windows Server 2008 is dramatically different from earlier releases of Windows Server operating systems. Windows Server 2008 is in fact so different from its predecessors that Microsoft considers earlier releases of Windows Server to be legacy operating systems, or admittedly at the very least to have legacy components. The way you approach Windows Server 2008 will depend on your background and your implementation plans. If you are moving to Windows Server 2008 from an earlier Windows server operating system or switching from UNIX, you’ll fi nd that Windows Server 2008 is a signifi cant change that requires a whole new way of thinking about the networking, application services, and the interoperations between clients and servers. The learning curve will be steep, but you will fi nd clear transition paths to Windows Server 2008. You will also fi nd that Windows Server 2008 has an extensive commandline interface that makes it easier to manage servers, workstations, and, indeed, the entire network using both graphical and command-line administration tools.

1. From the Run command, type in the path to the winnt32.exe file, either on the Windows 2000 CD-ROM or a network installation share point, and click OK.
2. The Welcome to the Windows 2000 Setup Wizard page appears. Select the Option to Upgrade to Windows 2000 (Recommended). Then click Next.
3. Read the License Agreement, then select the I accept this agreement option button. Then click Next.
4. Enter the 25-character Product Key. After entering the product key, click Next.
5. If your boot partition is FAT, you will be presented with the opportunity to upgrade it to NTFS 5. Select Yes, upgrade my drive. Then click Next.
6. Setup then copies the installation files. If you are using a CD-ROM, the copy phase is fairly quick, because only base system files required to start the installation during bootup are required. If you install from a network installation share point, all the files in the i386 folder will need to be copied to your machine in order to complete the installation.
7. When the file copy phase completes, the computer will reboot. From this point next, the upgrade and installation process will continue without user intervention.
