For years, it was the default tool for opening PDF files on Windows and Mac systems. Among its many iterations, stands out as a significant release that introduced modern features while marking the end of an era for Adobe's naming conventions.

However, as a legacy product that has not received a security update since 2017, its utility has passed. While it served millions of users faithfully during the early 2010s, it has no place on a modern, secure computer.

Security was a primary concern for Adobe, as PDFs had become a common vector for malware. Reader XI introduced "Protected Mode" (and later "Protected View"), a sandboxing technology that prevented malicious PDF files from executing code outside the Reader environment.

In previous versions, the free Reader was often limited in how users could interact with a document. Adobe Reader XI expanded the "Comment" pane, allowing users to use sticky notes, highlight text, draw shapes, and stamp documents. This transformed the free reader from a passive viewing tool into an active collaboration tool, provided the PDF author had enabled these permissions.
