Best-Selling Microsoft Software Licenses
US Trusted Tech offers a curated selection of Microsoft software licenses for customers in the United States. Whether you need a Windows license for a personal PC, an Office suite for home or business use, or server software for your organization, this collection brings together the most in-demand Microsoft products in one place.
Browse and compare editions, licensing options, device requirements, and product specifications across Windows 11, Windows 10, Microsoft Office 2024, Microsoft Office 2021, Windows Server, SQL Server, Microsoft Visio, Microsoft Project, Client Access Licenses (CALs), and Remote Desktop Services (RDS) licenses. Each product listing includes the details you need to choose the right license for your setup.
Windows 11 & Windows 10
Windows 11 and Windows 10 remain the most widely used desktop operating systems for home users, professionals, and businesses across the US. Understanding the differences between editions helps you choose the right license for your device and use case.
Windows 11 Home is designed for personal use on compatible PCs and laptops. It includes core features such as the redesigned Start menu, Microsoft Teams integration, and improved security through TPM 2.0 requirements.
Windows 11 Pro adds features suited to professionals and small businesses, including BitLocker encryption, Remote Desktop, Hyper-V virtualization, and Windows Sandbox.
Windows 10 Pro remains a practical choice for organizations running hardware that does not meet Windows 11 system requirements. Browse all available Windows 11 and Windows 10 licenses to compare editions and device requirements.
Microsoft Office 2024 & Office 2021
Microsoft Office perpetual licenses give you access to a specific version of Office applications without a recurring subscription. This is different from Microsoft 365, which requires an annual or monthly payment and includes cloud storage, regular feature updates, and multi-device access.
A perpetual Office license — such as Office 2024 or Office 2021 — is a one-time purchase that covers the version you buy. It does not automatically upgrade to future major versions.
Available editions include the Office 2024 Home & Business – Lifetime License Key and Office 2024 Professional Plus. Browse all available Microsoft Office licenses to compare editions, platforms, and included applications side by side.
Windows Server
Windows Server licensing is structured differently from consumer Windows licensing. Organizations need to account for the server edition, core licensing, and Client Access Licenses (CALs) for users or devices connecting to the server.
Windows Server 2025 is Microsoft's current server platform, offering improvements in security, hybrid cloud integration, and performance. Windows Server 2022 and Windows Server 2019 remain widely deployed in enterprise and SMB environments.
Before purchasing, review the edition (Standard or Datacenter), core count requirements, and whether your environment requires additional CALs. The Windows Server 2025 Standard – 16 Core License is one of the available server options — check the product listing for full specifications and CAL requirements.
SQL Server
SQL Server licensing depends on your deployment model, edition, and how users or applications connect to the database. Microsoft offers SQL Server under both per-core and Server plus CAL licensing models, and the right choice depends on your infrastructure and user count.
Browse available SQL Server products including the SQL Server 2025 Enterprise – 16 Core Perpetual License. Review each listing carefully for edition, core coverage, and included CAL details before purchasing.
Microsoft Visio & Project
Microsoft Visio is a diagramming application used by IT professionals, business analysts, engineers, and organizations to create flowcharts, network diagrams, org charts, and process maps. Microsoft Project is a project management tool used by project managers and teams to plan, track, and report on projects.
Both are available as perpetual licenses. Browse the Microsoft Visio Professional 2024 and Microsoft Project Professional 2024 listings for edition details and device requirements.
CALs & RDS Licenses
A Client Access License (CAL) is required for each user or device that accesses a Windows Server. CALs are not included with the server license itself and must be purchased separately based on your licensing model (User CAL or Device CAL).
Remote Desktop Services (RDS) CALs are required when users connect to a Windows Server remotely through Remote Desktop Services. RDS CALs are separate from standard Windows Server CALs and are required in addition to them. The number of CALs you need depends on your server environment, the number of users or devices, and your chosen licensing model.
