The interesting paper (likely from a reverse engineering forum like Woody’s Lounge , Reboot.pro , or a Chinese cracking group) outlines a multi-step process to break those dependencies:

: A powerful, open-source office suite that is natively designed to run from a USB drive and is compatible with Office 2007 file formats ( Microsoft 365

Creators use software like VMware ThinApp, Cameyo, or Spoon Studio to capture a clean installation of Office 2007.

Works seamlessly on any desktop or mobile device.

Before we focus on Office 2007 specifically, let’s clarify the concept of "portable" software. A portable application is one that does not require an installation process. It does not write to the Windows Registry or create system files on the host computer’s main drive. Instead, all settings, configurations, and executables are stored in a single folder.

Office 2007 was designed for hardware from the mid-2000s. It runs incredibly fast on modern computers and takes up a fraction of the storage space required by Microsoft 365 or Office 2021.

To keep the application "portable," developers often remove non-essential components such as Help files, Clipart, and additional language packs. Technical Implementation

Microsoft Office 2007 Portable Edition is a versatile and efficient productivity solution, designed to meet the needs of professionals, students, and individuals on-the-go. With its comprehensive set of tools, plug-and-play functionality, and data protection features, this portable edition offers users a secure and cost-effective solution for managing documents, spreadsheets, presentations, and databases. As technology continues to evolve and mobility becomes increasingly important, Microsoft Office 2007 Portable Edition remains a valuable resource for anyone seeking a reliable and portable productivity solution.

The Legacy, Risks, and Alternatives to Microsoft Office 2007 Portable Edition

Since Microsoft did not create a portable version, how do these repacks function? Most are created using like Cameyo, VMware ThinApp, or Evalaze. These tools wrap the application in a virtual environment that tricks Windows into thinking Office is installed.

Unless you are an enterprise IT professional with legacy software needs, this is not recommended.
