While both paths converge on the identical `MAS_AIO.cmd` logic, they handle elevation, architecture detection, and prerequisite validation differently. ## How PowerShell Execution Works in MAS ### Prerequisites and Launch Command The PowerShell method requires **Windows PowerShell 2.0+** running in **full language mode** (not *ConstrainedLanguage* or *RestrictedLanguage*). The standard one-liner downloads a remote wrapper that embeds the batch script: ```powershell # Standard execution irm https://get.activated.win | iex ``` For environments where DNS or ISP blocks interfere, use the DoH-wrapped variant: ```powershell iex (curl.exe -s --doh-url https://1.1.1.1/dns-query https://get.activated.win | Out-String) ``` According to the source code in `MAS/All-In-One-Version-KL/MAS_AIO.cmd` (lines 28‑48), the PowerShell wrapper validates the execution environment before proceeding. It checks for constrained language modes that would prevent script execution and exits with a troubleshooting link if detected. ### Environment Validation and Elevation When administrative rights are missing, the PowerShell script calls `Start-Process` with the `-Verb RunAs` parameter (lines 18‑24) to relaunch with elevated privileges. The wrapper also handles **architecture re-launching** via `re1` and `re2` flags (lines 53‑70) to ensure the batch file runs under the correct process bitness (x64, ARM64, etc.) before handing control to the underlying `MAS_AIO.cmd` logic. ## How CMD Execution Works in MAS ### Direct Batch File Entry Point The CMD method requires no PowerShell installation. Users download `MAS_AIO.cmd` directly from the repository or extract it from the release bundle, making it suitable for offline or restricted environments. The batch file serves as the primary entry point rather than a wrapper: ```cmd :: Direct download example curl -L -o MAS_AIO.cmd https://dev.azure.com/massgrave/Microsoft-Activation-Scripts/_apis/git/repositories/Microsoft-Activation-Scripts/items?path=/MAS/All-In-One-Version-KL/MAS_AIO.cmd&download=true :: Interactive execution MAS_AIO.cmd ``` As implemented in `MAS_AIO.cmd` (lines 72‑82), the script performs its own PowerShell availability checks solely to provide helpful error messages, but does not require PowerShell for core functionality. ### Architecture Handling and QuickEdit Disabling Unlike the PowerShell path, the batch file manages **re-launch logic** internally (lines 53‑70) to match the OS architecture. It also disables **QuickEdit mode** independently (lines 32‑40) using `reg` commands and optionally relaunches via `conhost.exe` to prevent terminal pauses during activation. For elevation, the batch checks `fltmc` (lines 18‑24) and calls `start cmd.exe -arg '/c "!_PSarg!"' -verb runas` to request administrator privileges without external dependencies. ## Key Differences Between PowerShell and CMD Methods - **Internet dependency**: **PowerShell** requires a live connection to fetch the remote script; **CMD** works entirely offline once the batch file is local. - **Language mode constraints**: **PowerShell** fails early if running in *ConstrainedLanguage* mode (lines 34‑48); **CMD** has no such restriction. - **Entry point**: **PowerShell** uses a transient wrapper that writes `MAS_AIO.cmd` to a temp location; **CMD** executes the batch file directly. - **Update checking**: Both methods perform version checks (lines 46‑77), but the PowerShell wrapper handles this before the batch launches, while the batch file contains identical logic for standalone use. ## Code Examples for Both Methods ### PowerShell One-Liners ```powershell # Basic remote execution irm https://get.activated.win | iex # DNS-over-HTTPS variant for blocked networks iex (curl.exe -s --doh-url https://1.1.1.1/dns-query https://get.activated.win | Out-String) ``` After execution, the wrapper: 1. Saves the embedded batch content to a temporary file. 2. Invokes the batch with user-selected activation parameters. ### CMD Execution with Parameters ```cmd :: HWID activation for Windows MAS_AIO.cmd /HWID :: Office activation via Ohook MAS_AIO.cmd /Ohook :: Online KMS for both Windows and Office MAS_AIO.cmd /K- :: TSforge activation (Windows/ESU/Office) MAS_AIO.cmd /Z- ``` The batch file automatically detects the OS version, elevates if required via `fltmc` checks, and performs built-in diagnostics (Internet connectivity, Windows Update service status) before attempting activation. ## Summary - **PowerShell method** (`irm...|iex`): Best for quick, one-line execution when internet access is available and the remote source is trusted. Validates language mode early but requires unrestricted PowerShell. - **CMD method** (`MAS_AIO.cmd`): Ideal for offline environments, restricted networks, or when local control over parameters and silent operation is required. No PowerShell prerequisite. - **Convergence**: Both methods execute identical logic from `MAS/All-In-One-Version-KL/MAS_AIO.cmd` after handling environment-specific prerequisites. - **Troubleshooting**: Use `MAS/Separate-Files-Version/Troubleshoot.cmd` to diagnose PowerShell language mode issues or missing modules regardless of the chosen entry point. ## Frequently Asked Questions ### Do both methods run the same activation logic? Yes. The PowerShell one-liner downloads a wrapper that extracts and executes `MAS_AIO.cmd` with the same arguments (`-el …`) used in direct CMD execution. The HWID, Ohook, TSforge, and KMS activation routines are identical regardless of how you launch the script. ### Which method should I use if PowerShell is blocked? Use the **CMD method**. Download `MAS_AIO.cmd` directly from the repository or Azure DevOps artifacts. The batch file includes its own elevation and architecture detection logic and does not require PowerShell to complete activation. ### Can I run MAS offline? Only with the **CMD method**. The PowerShell one-liner requires internet access to fetch the remote script. Once you have a local copy of `MAS_AIO.cmd`, all activation methods function without network connectivity, though online KMS activation naturally requires internet access to reach Microsoft servers. ### How does architecture detection differ between methods? In **PowerShell**, the wrapper handles re-launching for correct bitness (x64 vs. x86 vs. ARM64) via `start … re1` / `re2` flags before invoking the batch. In **CMD**, the batch file manages this internally (lines 53‑70) using the same flag system, ensuring the activation logic runs under the appropriate process architecture without external assistance.
