Inside WSA Installer: The 6 Automated Phases

Why a Tool at All?

Installing WSA correctly means enabling Windows features, downloading the right build, extracting a 7z archive, patching binaries, registering the subsystem, and integrating Play Store. WSA Installer automates every step through a 5-step frameless wizard.

Phase 1 — Smart System Scan

The installer detects VT-x, Hyper-V, VirtualMachinePlatform, HypervisorPlatform, and WSL using five methods (CPUID, wmic, systeminfo, PowerShell, registry). If anything is missing it offers to enable it automatically with admin rights.

Phase 2 — Auto Configuration

Required Windows features are turned on via DISM and the system may prompt for a restart. No BIOS hunting, no manual feature dialogs.

Phase 3 — Parallel Chunked Download

The WSA archive is fetched in 30 parallel chunks with resume support, live speed, and ETA. The same engine powers the self-update system.

Phase 4 — Extract & Patch

The 7z archive is extracted with tar.exe, WsaClient.exe is binary-patched for Windows 10 (WSAPatch), and the package is verified against filelist.txt before registration.

Phase 5 — Play Store Patching

MindTheGapps 13.0 is merged via MagiskOnWSALocal. ADB authorization is automated through pywinauto GUI scripting, so Play Store appears in the Start Menu without manual commands.

Phase 6 — Complete & Background Service

Shortcuts are created, WSABackgroundService is registered as a Windows service, and the subsystem launches. The background service keeps ADB and file shares alive and auto-restarts on failure.
