📦 Intro

This repository publishes a standalone offline Windows x64 distribution intended for the Microsoft Office Ultimate workflow. The package bundles the document editing, spreadsheet, and presentation components into a single self-contained setup for Windows 10 and 11. Every artifact is versioned and reproducible from the release page.

The build is aimed at operators who deploy office productivity tooling into air-gapped workstations, bandwidth-constrained environments, or reproducible lab images. Because the distribution ships as a single offline bundle, the same file can be staged on a local share and applied identically across a fleet without fetching components from the network at install time.

The distribution supports document and spreadsheet formats, bundled templates, and both portable and installed deployment modes. A single Microsoft Office Ultimate on Windows deployment covers both modes from one package, which keeps staging and validation consistent.

02 · ✨ Features

📝 Document Authoring Rich text editing with styles, tables, headers, and page layout controls for structured reports.	📈 Spreadsheet Engine Formula evaluation, pivot summaries, and cell formatting for tabular analysis workflows.	🎞 Slide Deck Builder Presentation canvas with layouts, transitions, and speaker notes for review meetings.
🗂 Template Library Bundled document, sheet, and deck templates staged locally so no network fetch is required.	💾 Portable Mode Self-contained run mode that keeps user data beside the binary for removable-media deployment.	🔐 Hash Verification Every release artifact ships with a SHA256 digest so operators can validate staged copies.

03 · ⚙️ How it works

The installer delivers the application binaries into a versioned program directory and stages shared runtime libraries alongside them. User documents, templates, and preferences are written to the user profile, keeping system directories untouched by default.

On first launch the build registers its file associations and shell integration entries for the current user through the Windows registry. Default configuration is seeded from the bundled template set on first run, and no components are fetched from the network during initialization.

At runtime the build operates fully offline; document processing, spreadsheet recalculation, and slide rendering all happen locally on the host. Updates are applied by running a newer versioned installer over the existing install, which preserves the profile data and template customizations already on disk.

Integration with Windows is limited to per-user registry keys for file associations and Start menu shortcuts. The build can coexist with other installations of similar office suites because each version writes to its own program directory and does not claim global file handlers unless the operator opts in.

04 · 🧩 Compatibility

The build targets Windows 10 and Windows 11 on x64 hardware only. Both Home and Pro editions are supported, and no specific minimum build number is enforced beyond a current-servicing Windows 10 or 11 release. 32-bit Windows targets are out of scope.

PowerShell 5.1 and PowerShell 7 or later are both supported for the installer wrapper. The wrapper uses standard cmdlets for hash validation and directory staging, and does not require any external PowerShell modules.

The build runs on typical modern office workstation hardware and is comfortable on machines with a standard amount of memory and free disk space for the application and user documents. Exact resource use depends on document size and number of concurrently open files.

Portable and installed modes coexist cleanly because each maintains its own configuration path. When a second version is installed, the operator controls which build owns file associations through the per-user registry entries, so Windows opens documents with the intended installation.

06 · ❓ FAQ

🔒 Is this standalone build safe to install on Windows?

[!CAUTION] On first run, Windows SmartScreen may warn for unsigned installers. Click More info, then Run anyway to continue. The build is an offline setup file; keep your antivirus enabled as usual.

🪟 Which Windows versions does the build support?

[!NOTE] The build runs on Windows 10 and Windows 11 on x64. Older Windows releases and 32-bit targets are not supported.

📡 Can I use the build offline?

[!TIP] Yes. After install, the build runs without a network connection. Only the initial retrieval step needs internet access.

🔄 How do updates work?

[!NOTE] Updates ship as a newer versioned installer; running it over the existing install preserves your documents, templates, and preferences. No separate updater service is required.

🗑️ How do I uninstall it on Windows?

[!WARNING] Open Settings, then Apps, then Installed apps, find the entry in the list, and choose Uninstall. Personal document files remain on disk unless you remove them manually.

⚙️ What are the technical specifications?

[!IMPORTANT]

• System load: Light to moderate, scaling with open document size and number of concurrent files.
• File formats: Imports and exports common document, spreadsheet, and presentation formats used in office workflows.
• Portable build: A portable variant is available for removable-media deployment alongside the standard install.

🔐 How do I verify the file with SHA256?

[!CAUTION] Open PowerShell in the folder with the installer and run Get-FileHash setup.exe -Algorithm SHA256. Compare the output with the hash published alongside the release. If they do not match, delete the file and fetch it again.

🛡️ Does the build require administrator rights?

[!TIP] Standard user access is sufficient for the default install location. Administrator rights are only requested if you choose a system-wide install path during setup.

📂 Where does the build place its files?

[!NOTE] By default, the installer uses the per-user program directory for the application and the user profile for configuration. No files are written to Windows system directories.

📶 Does the build collect telemetry?

[!TIP] This standalone build does not include telemetry or usage reporting. All processing happens locally on the Windows host.

🐛 How do I report an issue?

[!NOTE] Open a new issue on this repository with Windows version, build hash, and the reproduction steps. Include any installer log lines from %TEMP% if available.
