LKY_OfficeTools
一键自动化 下载、安装、激活 Office 的利器。
A one-click Windows utility that automatically downloads, installs, and activates Microsoft Office. Detects your architecture, lets you pick which components to install, and removes old Office versions. For personal study only, not commercial use.
LKY Office Tools is a Windows utility written in C# that automates the process of downloading, installing, and activating Microsoft Office. Instead of visiting Microsoft's website, selecting the right installer, running it manually, and then working through activation separately, this tool handles the entire sequence in one click. It is free, open source, and the authors describe it as containing no malware.
When you run the tool, it automatically detects your Windows architecture, either 32-bit or 64-bit, and fetches the matching Office build. You start by installing the core apps, Word, PowerPoint, and Excel, and during that process the tool also prompts you to optionally add Outlook, OneNote, Access, Visio, Project, Publisher, Teams, OneDrive, and Lync/Skype. You choose which components you want before anything downloads.
The activation method is described as a genuine activation mode that does not alter any system files. If your computer already has multiple older or redundant versions of Office on it, the tool can detect them and, with your consent, remove or upgrade them automatically so you end up with a clean, single installation.
The project requires Windows 10 version 1703 or later, and works on both x86 and x64 machines. Older Windows releases from before July 2016 are not supported because they cannot run the current versions of Office that this tool installs.
The repository is open source, but the authors are explicit that the auto-activation feature is meant for personal learning and programming study only. Using it for commercial office work is not within the stated scope. For any business or organizational use, the authors recommend purchasing a license from Microsoft directly. Redistribution or resale of the tool is prohibited.
Where it fits
