# Activate-MicrosoftOffice
**PowerShell tool to activate Microsoft Office 2016 - 2024 via static Professional Plus KMS client keys.**

_(Note: this works on **local** installations of Microsoft Office, and has nothing to do with cloud-based Office 365)_

## Description

_"What are KMS keys?"_
> Essentially, Key Management System (KMS) client keys are static enterprise keys designed to handle large-scale activation within an organization.  They generally rely on a local KMS activation server, allowing organizations to activate multiple clients on their network via volume licensing, rather than each individual client connecting to Microsoft for activiation.
>
> In contrast, consumer keys (such as retail or OEM) are essentially dynamic, one-time-use keys intended for small-scale, individual user activation.  These are what you usually use when you activate your product.

This project modifies local versions of Microsoft Office to utilize Microsoft's static KMS client keys rather than one-time-use consumer keys.  The Office instance is then activated with a Professional Plus KMS client key via a publicly available KMS activation server.

This PowerShell script supports Microsoft Office 2016, 2019, 2021, and 2024 -- and has been tested on both Windows 10 and Windows 11.

- **Script Features:**
  - Supports both 32-bit and 64-bit versions of Office.
  - Supports Microsoft Office 2016, 2019, and 2021.
  - Script works with both Desktop PowerShell and PowerShell Core.
  - Contains moderate error correction.
  - **[Version 1.1.0]** Supports custom KMS servers and ports.
  - **[Version 2.0.0]** Remove `GET GENUINE OFFICE` banner via version rollback & disabled auto-updates.
  - **[Version 2.0.1]** Minor visual formatting adjustments.
