Which of the following is NOT considered a key workstation in the financial market?

In the context of financial markets, key workstations are specialized technological platforms that provide critical analytical tools, real-time data, and information to help financial professionals make informed decisions. Eikon, CapIQ, and FactSet are all recognized as major financial data and analytics platforms widely used by professionals in the finance industry for a variety of purposes including market analysis, portfolio management, and financial research. These systems are specifically tailored to meet the needs of finance professionals and often incorporate real-time market data, financial modeling tools, and access to various financial resources.

In contrast, Windows is an operating system that serves as the underlying software environment on which various applications, including financial platforms, run. While Windows is essential for facilitating the operation of financial applications, it does not provide specialized financial analytics or market data itself. Therefore, it does not fit within the defined category of key workstations that are integral to the financial markets. Its primary function is to support software applications rather than provide direct financial insights or data analysis capabilities. This distinction is why Windows is identified as the option that is not considered a key workstation in the financial market context.
