Windows 10 Professional (often called Windows 10 Pro) is the business-focused edition of Microsoft's Windows 10 operating system, part of the Windows NT family and designed for desktops, laptops, workstations, and 2-in-1 devices. It was first released on July 29, 2015, alongside Windows 10 Home, and has since received regular feature updates, with version 22H2 being the final major release.

Windows 10 Pro includes all the core features of Windows 10 Home plus additional business-oriented capabilities such as BitLocker device encryption, Windows Information Protection (WIP), Remote Desktop, Group Policy management, Hyper-V virtualization, and support for Windows Update for Business and Azure Active Directory domain joining. It supports up to 2 TB of RAM (64-bit) and allows connection to on-premises Active Directory domains, making it suitable for small to medium businesses and power users.

Microsoft officially ended mainstream support for Windows 10 Home and Pro on October 14, 2025, meaning no further free security or quality updates are provided after that date for standard installations. However, Microsoft introduced an Extended Security Updates (ESU) program that allows eligible consumer and commercial devices to continue receiving critical security patches through October 12, 2027, for a fee. Enterprise LTSC editions have separate, longer support lifecycles extending into 2027 and beyond.

Because Windows 10 is now in its end-of-life phase, buyers on cdkeycompares.com should carefully consider whether a Windows 10 Pro license is appropriate for their use case. For new builds or long-term deployments, Windows 11 may be a better choice, while Windows 10 Pro remains relevant for legacy systems, specialized hardware, or environments where ESU coverage is planned.
