Windows CE 5.0

Windows CE 5.0 (codenamed "Macallan") is a successor to Windows CE 4.2, the third release in the Windows CE .NET family.

It was first released on July 09, 2004. Like its predecessors, Windows CE 5.0 is marketed towards the embedded device market and independent device vendors. Windows CE 5.0 is billed as a low-cost, compact, fast-to-market, real-time operating system available for x86, ARM, MIPS, and SuperH microprocessor-based systems. Windows CE 5.0 builds on previous Windows CE releases in its adoption of shared source. Since 2001, Microsoft has been steadily expanding the available Windows CE source tree with embedded system developers. Windows CE 5.0 is the most open Microsoft Operating System to date, though not all of the system is available under shared source agreements. Developers have the freedom to modify down to the kernel level, without the need to share their changes with Microsoft or competitors.

Windows CE 5.x is the base OS for Windows Mobile 6.0, 6.1 and 6.5. On the x86 platform, Windows CE 5.0 competes against Microsoft's other embedded Operating Systems, Windows XP Embedded and its predecessor Windows NT Embedded.

Platform Builder IDE for Windows CE 5.0 is the last builder tool available as standalone product.
