# Comprehensive MAS Command-Line Switches and Parameter Reference > **MAS (Microsoft Activation Scripts) supports unattended activation via command-line switches that invoke specific modules (HWID, Ohook, TSforge, Online KMS) and modify activation behavior without user interaction.** - Repository: [MASSGRAVE/Microsoft-Activation-Scripts](https://github.com/massgravel/Microsoft-Activation-Scripts) - Tags: api-reference - Published: 2026-02-24 --- **MAS (Microsoft Activation Scripts) supports unattended activation via command-line switches that invoke specific modules (HWID, Ohook, TSforge, Online KMS) and modify activation behavior without user interaction.** The `MAS_AIO.cmd` script from the **massgravel/Microsoft-Activation-Scripts** repository serves as the central dispatcher, parsing global flags and delegating to specialized activation modules. This reference documents every documented switch extracted directly from the source code, enabling fully automated Windows and Office activation workflows. ## Global Switches (MAS_AIO.cmd) The master script `MAS/All-In-One-Version-KL/MAS_AIO.cmd` processes the following switches before routing to the appropriate activation module. - **`-el`** – Forces administrative elevation. If the current session lacks privileges, the script re-launches itself using `runas`. Implemented as `if /i "%%A"=="-el" set _elev=1`. - **`/HWID`** – Invokes the HWID activation routine. The script detects this in the unattended block and calls `:HWIDActivation`. - **`/HWID-NoEditionChange`** – Runs HWID activation without automatically changing the Windows edition. Useful on editions that natively do not support HWID. Sets `_NoEditionChange=1`. - **`/Ohook`** – Invokes the Office Ohook activation routine. Detected in the unattended block and calls `:OhookActivation`. - **`/K-…`** – Invokes the **Online KMS** activation routine. Any switch beginning with `/K-` triggers `call :KMSActivation` and is parsed inside `Online_KMS_Activation.cmd`. - **`/Z-…`** – Invokes the **TSforge** activation routine. Any switch beginning with `/Z-` triggers `call :TSforgeActivation` and is parsed inside `TSforge_Activation.cmd`. ## TSforge Activation Switches (/Z- Parameters) The `MAS/Separate-Files-Version/Activators/TSforge_Activation.cmd` module handles the most extensive switch set, supporting Windows, ESU, Office, and advanced activation methods. ### Product Selection Switches - **`/Z-Windows`** – Activate Windows only (default HWID-style activation). Sets `_actwin=1`. - **`/Z-ESU`** – Activate **Extended Security Updates (ESU)** for Windows 10/11. - **`/Z-Office`** – Activate **all Office products** including Project and Visio. - **`/Z-ProjectVisio`** – Activate **Project & Visio** only. - **`/Z-WindowsESUOffice`** – Activate **Windows + ESU + Office** in a single operation. - **`/Z-WinHost`** – Activate the **Windows KMS host** (csvlk). - **`/Z-OffHost`** – Activate the **Office KMS host** (csvlk). - **`/Z-APPX`** – Activate **Windows 8/8.1 APPX sideloading** (APPXLOB). ### Advanced Method Switches - **`/Z-ID-`** – Force activation of a **specific activation ID**. Multiple IDs can be supplied by repeating the switch. The parser detects the `/Z-ID-` prefix, extracts the GUID, and appends it to the `tsids` variable. - **`/Z-Reset`** – **Reset** the re-arm counter, evaluation period, tamper state, and/or key-lock. - **`/Z-SCID`** – Force the **Static CID** activation method, overriding auto-selection. Sets `_actmethod=SCID`. - **`/Z-ZCID`** – Force the **Zero CID** activation method. Sets `_actmethod=ZCID`. - **`/Z-KMS4k`** – Force the **KMS4k** activation method, used when internet connectivity is unavailable on newer builds. Sets `_actmethod=KMS4k`. ## HWID Activation Switches (/HWID Parameters) The `MAS/Separate-Files-Version/Activators/HWID_Activation.cmd` module processes hardware-based activation. - **`/HWID`** – Activate Windows using the **HWID** method. Sets `_act=1`. - **`/HWID-NoEditionChange`** – Skip automatic edition-change logic. Essential for Windows editions that do not support HWID activation. - **`-el`** – Request elevation (global flag, also accepted here). ## Ohook Activation Switches (/Ohook Parameters) The `MAS/Separate-Files-Version/Activators/Ohook_Activation_AIO.cmd` module handles Office activation. - **`/Ohook`** – Activate **Office** (including Project/Visio) via the Ohook method. Detected globally in `MAS_AIO.cmd` and delegated to `:OhookActivation`. - **`-el`** – Request elevation. ## Online KMS Activation Switches (/K- Parameters) The `MAS/Separate-Files-Version/Activators/Online_KMS_Activation.cmd` module parses switches beginning with `/K-`. The switch set mirrors the TSforge options: - **`/K-Windows`** – Activate Windows via an online KMS server. - **`/K-Office`** – Activate Office (including Project/Visio) via online KMS. - **`/K-WinHost`** – Activate the Windows KMS host (csvlk). - **`/K-OffHost`** – Activate the Office KMS host (csvlk). - **`/K-APPX`** – Activate Windows 8/8.1 APPX sideloading via online KMS. - **`-el`** – Request elevation. ## Practical Usage Examples Execute these commands from an elevated Command Prompt or PowerShell session. Run HWID activation unattended with automatic elevation: ```batch MAS_AIO.cmd /HWID -el ``` Activate Windows, ESU, and Office simultaneously using the Static CID method: ```batch MAS_AIO.cmd /Z-WindowsESUOffice /Z-SCID -el ``` Force activation of specific activation IDs (multiple IDs allowed): ```batch MAS_AIO.cmd /Z-ID-55c92734-d682-4d71-983e-d6ec3f16059f /Z-ID-43c9f5a8-3d2c-49f9-b2a5-6bff5b3d78ab -el ``` Reset evaluation periods and re-arm counters, then activate via HWID: ```batch MAS_AIO.cmd /Z-Reset /HWID -el ``` Activate Office only using the Ohook method: ```batch MAS_AIO.cmd /Ohook -el ``` Activate Windows via online KMS: ```batch MAS_AIO.cmd /K-Windows -el ``` ## Summary - **Global dispatcher**: `MAS_AIO.cmd` parses `-el`, `/HWID`, `/Ohook`, `/K-…`, and `/Z-…` switches, then delegates to the appropriate activation module. - **TSforge flexibility**: The `/Z-` prefix offers the most granular control, supporting specific product activation (`/Z-Windows`, `/Z-ESU`, `/Z-Office`), custom activation IDs (`/Z-ID-`), and method overrides (`/Z-SCID`, `/Z-KMS4k`). - **Edition safety**: Use `/HWID-NoEditionChange` when activating editions that do not natively support HWID to prevent unwanted SKU changes. - **Elevation handling**: The `-el` switch ensures the script runs with administrative rights, re-launching via `runas` if necessary. - **Unattended mode**: Supplying any activation switch automatically sets `_unattended=1`, suppressing interactive menus. ## Frequently Asked Questions ### What is the difference between /Z-SCID, /Z-ZCID, and /Z-KMS4k? These switches force specific TSforge activation methods. **`/Z-SCID`** uses the Static CID method, **`/Z-ZCID`** uses the Zero CID method, and **`/Z-KMS4k`** uses the KMS4k method designed for scenarios where internet access is unavailable on newer Windows builds. By default, the script auto-selects the appropriate method unless overridden. ### Can I combine multiple activation targets in a single command? Yes. You can combine product selectors like `/Z-WindowsESUOffice` to activate multiple products simultaneously, or chain individual switches such as `/Z-Windows /Z-Office`. You may also combine activation with reset operations using `/Z-Reset` to clear evaluation states before activating. ### Does MAS require administrative privileges to run? Yes. While the script can launch without elevation, activation operations require administrative rights. Use the **`-el`** switch to force elevation; if the current session is not elevated, `MAS_AIO.cmd` will re-launch itself with the necessary privileges using `runas`. ### How do I activate a specific Windows edition that is not currently installed? Use the **`/Z-ID-`** switch with the specific GUID of the target edition. This bypasses edition detection and forces activation of that specific ID. You can specify multiple IDs in a single command by repeating the switch with different GUIDs.
