Introduction

Windows remains the dominant desktop operating system worldwide, powering millions of PCs in homes and offices. While Windows ships with a comprehensive set of native tools and applications, many users find these built-in apps sometimes lack speed, features, or customizability. Fortunately, a robust ecosystem of free, open source software exists that can replace or supplement default Windows apps, granting users more control and improved productivity without spending a dime.
