[Generated for Academic Review] Date: April 14, 2026 Abstract The modern enterprise faces a persistent tension between computational power, data security, and total cost of ownership (TCO). While traditional fat clients (PCs) offer local processing, they introduce vulnerabilities and management overhead. This paper examines the resurgence of the thin client computing model, specifically focusing on implementations running Microsoft Windows operating systems (Windows 10/11 IoT Enterprise LTSC or Windows CE). We analyze the architectural shift from distributed to centralized computing, evaluate the security posture of thin clients in zero-trust environments, and present a quantitative TCO model. The findings indicate that while legacy thin clients suffered from poor multimedia performance, modern Windows-based thin clients leveraging Remote Desktop Protocol (RDP) and Azure Virtual Desktop (AVD) can achieve near-native performance, reduce annual IT labor costs by up to 65%, and significantly lower the attack surface for ransomware. 1. Introduction For three decades, the personal computer has dominated enterprise infrastructure. However, the proliferation of cloud computing, Software-as-a-Service (SaaS), and remote work has exposed the inefficiencies of managing thousands of distributed, stateful endpoints. The thin client—a stateless device that connects to a centralized server for all processing—offers a compelling alternative. We analyze the architectural shift from distributed to
The thin client model saves ~34.6% over three years, primarily through hardware longevity and reduced support labor. The breakeven point occurs at month 14. 6. Performance Case Study Scenario: Engineering firm running AutoCAD LT 2025 and Microsoft Teams. Hardware: Dell Wyse 5070 (Intel Gemini Lake, 8GB RAM) vs. Dell OptiPlex (Core i5, 16GB RAM). Connection: 1 Gbps LAN, 20 ms latency. Introduction For three decades, the personal computer has
