The Serial Numbers feature in PC Guard is a comprehensive system designed to identify and track individual copies of protected software, proving particularly useful when software is distributed through indirect channels like resellers or retail stores. This feature is compatible with the REMOTE, PLAIN, and USB protection methods but is explicitly unavailable for the NETWORK protection method.

This article synthesizes the core application protection capabilities offered by Software Protection Labs' PC Guard, focusing on its encryption and password protection features. The primary goal of these features is to enhance application security against unauthorized access and malicious modification.

The PC Guard software protection suite includes a comprehensive "Demo mode" feature designed to create robust trial versions of applications. This mode operates by imposing one or more limitations on the protected software, which can be combined as needed. There are four primary types of limitations: a finite number of executions (number of runs), a set number of days from the first launch, a fixed calendar period, and a cap on total application runtime.

The PC Guard security feature set provides a multi-layered defense mechanism designed to protect software applications from tampering, reverse engineering, and unauthorized usage in specific environments. The protection strategy is built around a core of integrity checks and anti-debugging measures that are enabled by default, ensuring a robust baseline of security. Key default features include self-checking for modifications, memory anti-dumping, debugger detection, and the renaming of executable sections.

The General Settings for PC Guard provide a comprehensive suite of options for managing application compatibility, security, and licensing behavior. The configurations address common issues arising from the software protection process, particularly for non-standard applications and specific operating environments.

The "Application info" settings within PC Guard are foundational for defining a protected application's identity, licensing behavior, and update strategy.

This article provides a comprehensive analysis of the redistributable files required for applications protected by SOFPRO's PC Guard software. While PC Guard embeds its core protection and licensing code directly into the protected application, certain configurations and features necessitate the distribution of additional files.

This blog post synthesizes the best practices for implementing software protection. The central recommendations focus on robust project configuration, enhanced security measures, and a seamless end-user experience.

The PC Guard software protection suite features a robust command line interface (CLI) designed to fully automate the application protection process. By invoking the PC Guard executable with specific parameters, developers can integrate protection into build scripts, batch files, and other automated workflows.

This document provides a comprehensive overview of the PC Guard software protection technology, a solution designed to prevent reverse engineering, illegal distribution, and unauthorized use of Windows applications. PC Guard operates as an "out-of-the-box" system, wrapping compiled applications in a secure envelope without requiring source code modification, making it accessible to developers of all skill levels.
