 `wsl` enables WSL prerequisites, installs the current official `FedoraLinux-*` distro reported by `wsl --list --online`, stops for reboot or first-launch username creation when needed, then invokes the latest Linux bootstrap release with `--wsl --headless --yes`.

+## Tests
+
+Unit tests run on every pull request via `.github/workflows/unit-test.yml`:
+
+```powershell
+go test ./...
+```
+
+End-to-end integration runs against a real Windows client VM through Vagrant +
+Hyper-V. It is not run in CI (GitHub-hosted runners are Windows Server and have
+no Hyper-V), so execute it locally:
+
+```powershell
+go run ./test/integration
+```
+
+See `test/integration/README.md` for prerequisites, flags, and tuning options.

 ## Current Deferrals

 `Webcamoid` is deferred because no exact `winget` manifest was available during implementation. Native Docker Desktop, Podman Desktop, Buildah, Minikube, Firecracker, QEMU, virt-manager, Windows Terminal, and VS Code are also intentionally excluded from Windows v1.

+# Integration test (Vagrant + Hyper-V)
+
+`bootstrap_windows_env` runs against Windows 10/11 client SKUs only — Windows
+Server (which is what GitHub-hosted runners provide) does not support several
+of the features the bootstrapper exercises (System Restore checkpoints,
+Microsoft Store package updates, the Chris Titus Tech WinUtil flows, etc.).
+The integration test therefore runs locally on a Windows host against a real
+Windows client virtual machine through Hyper-V, driven by Vagrant.
+
+## Prerequisites
+
+On the host machine:
+
+- Windows 10/11 Pro or Enterprise (or Windows Server) with the **Hyper-V**
+  role enabled.
+- The host user must be a member of the **Hyper-V Administrators** local
+  group.
+- [HashiCorp Vagrant](https://developer.hashicorp.com/vagrant/downloads)
+  2.4 or newer in `PATH`.
+- Go (the same toolchain version pinned in `go.mod`) — used both to build the
+  bootstrapper and to run the integration driver.
+- A Hyper-V-compatible Windows client Vagrant box. The default is
+  [`gusztavvargadr/windows-11`](https://portal.cloud.hashicorp.com/vagrant/discover/gusztavvargadr/windows-11),
+  which ships with WinRM enabled and the standard `vagrant`/`vagrant`
+  credentials. To build your own from a Windows 11 ISO, see
+  [`packer/README.md`](packer/README.md) and then set
+  `BOOTSTRAP_BOX=bootstrap-win11` (or edit the Vagrantfile default).
+
+## Running the test
+
+From the repository root:
+
+```powershell
+go run ./test/integration
+```
+
+That will:
+
+1. Cross-build `dist/bootstrap_windows_env.exe` for `windows/amd64`.
+2. `vagrant up --provider=hyperv` against `test/integration/Vagrantfile`.
+3. `vagrant upload` the binary into the guest at `C:\Users\vagrant\bootstrap_windows_env.exe`.
+4. Execute the binary inside the guest via `vagrant powershell -c "& ... --yes --no-wsl"`.
+5. `vagrant destroy -f` regardless of pass/fail (use `--keep` to preserve the VM).
+
+## Flags
+
+| Flag           | Default                       | Description                                                                  |
+|----------------|-------------------------------|------------------------------------------------------------------------------|
+| `--args`       | `--yes --no-wsl`              | Arguments passed to `bootstrap_windows_env.exe` inside the guest.            |
+| `--keep`       | `false`                       | Leave the VM running after the test for debugging.                           |
+| `--skip-build` | `false`                       | Reuse `dist/bootstrap_windows_env.exe` instead of rebuilding it.             |
+| `--provider`   | `hyperv`                      | Vagrant provider name (only `hyperv` is supported).                          |
+| `--timeout`    | `90m`                         | Overall timeout. The Vagrantfile has its own WinRM/boot timeouts on top.     |
+
+## Vagrantfile environment overrides
+
+The Vagrantfile reads these environment variables so you can tune the VM
+without editing the file:
+
+| Variable                  | Default                       | Description                                  |
+|---------------------------|-------------------------------|----------------------------------------------|
+| `BOOTSTRAP_BOX`           | `gusztavvargadr/windows-11`   | Vagrant box reference.                       |
+| `BOOTSTRAP_BOX_VERSION`   | _(unset)_                     | Pin a specific box version.                  |
+| `BOOTSTRAP_HOSTNAME`      | `bootstrap-it`                | Guest hostname.                              |
+| `BOOTSTRAP_CPUS`          | `8`                           | Guest vCPU count.                            |
+| `BOOTSTRAP_MEMORY`        | `16384`                       | Guest startup memory (MB).                   |
+| `BOOTSTRAP_MAX_MEMORY`    | `16384`                       | Guest dynamic-memory ceiling (MB).           |
+| `BOOTSTRAP_BOOT_TIMEOUT`  | `1800`                        | Vagrant boot timeout (seconds).              |
+| `BOOTSTRAP_WINRM_USER`    | `vagrant`                     | Guest WinRM user.                            |
+| `BOOTSTRAP_WINRM_PASS`    | `vagrant`                     | Guest WinRM password.                        |
+| `BOOTSTRAP_WINRM_TIMEOUT` | `3600`                        | Per-WinRM-command timeout (seconds).         |
+| `BOOTSTRAP_WINRM_RETRIES` | `30`                          | WinRM retry attempts during `vagrant up`.    |
+
+## Notes
+
+- There is no official Vagrant SDK for Go — Vagrant is a Ruby project — so the
+  driver shells out to the `vagrant` CLI. This is the conventional pattern for
+  Go programs orchestrating external tools.
+- The Hyper-V provider cannot reliably share folders without prompting for SMB
+  credentials, so the driver pushes the bootstrapper into the guest with
+  `vagrant upload` and disables the default synced folder.
+- This test is intentionally **not** wired up to GitHub Actions: hosted runners
+  do not expose Hyper-V and run Windows Server, which the bootstrapper does

+# Vagrant box build (Packer + Hyper-V + Windows 11 25H2)
+
+Builds a `bootstrap-win11.box` Vagrant box from a stock Windows 11 25H2 ISO,
+ready to use with `test/integration/Vagrantfile`.
+
+## Prerequisites
+
+On the host (must be Windows with Hyper-V):
+
+- Hyper-V role enabled; current user in **Hyper-V Administrators**.
+- [HashiCorp Packer](https://developer.hashicorp.com/packer/install) 1.15+ in
+  `PATH`. HashiCorp does not publish a winget manifest, so use the helper:
+
+  ```powershell
+  # from an elevated PowerShell
+  cd test\integration\packer
+  .\install-packer.ps1                 # installs the pinned default version
+  .\install-packer.ps1 -Version 1.14.0 # or pick a specific release
+  ```
+
+  The script downloads
+  `https://releases.hashicorp.com/packer/<Version>/packer_<Version>_windows_amd64.zip`,
+  extracts `packer.exe` to `C:\Program Files\Packer\`, and adds that directory
+  to the machine-scoped `PATH`. It is idempotent — re-running with the same
+  version just re-asserts the `PATH` entry. See the `param()` block in
+  `install-packer.ps1` for available flags.
+
+  By default the same script also installs **Windows ADK Deployment Tools**
+  to get `oscdimg.exe`, which Packer's `hyperv-iso` builder needs to build the
+  unattended-install secondary ISO from `cd_files`. Only the
+  `OptionId.DeploymentTools` feature is selected, so the install is small
+  (~70 MB) and unattended. Pass `-SkipOscdimg` to opt out (e.g. if you already
+  have `xorriso`/`mkisofs` on `PATH`). After install you may need to open a
+  fresh shell — or run
+  `$env:Path = [Environment]::GetEnvironmentVariable('Path','Machine')` — for
+  `oscdimg.exe` to resolve in the current session.
+- [HashiCorp Vagrant](https://developer.hashicorp.com/vagrant/install) 2.4+ in
+  `PATH` (used for the `vagrant` post-processor and, later, the integration
+  test itself).
+- A Windows 11 client ISO somewhere on disk. Its path is read from `.env`
+  (see below) and is **not** hardcoded in the Packer config.
+- Roughly 90 GB free disk and ~60 minutes of patience for a first build.
+- An elevated PowerShell session for the build (`packer build` shells out to
+  Hyper-V management APIs that require admin).
+
+## Configure the ISO path via `.env`
+
+The Packer config has no default ISO path. Copy the template, fill it in, and
+load it into the current shell before building:
+
+```powershell
+cd test\integration\packer
+Copy-Item .env.example .env
+# edit .env so PKR_VAR_iso_path points at your Windows 11 ISO
+. .\load-env.ps1
+```
+
+`load-env.ps1` reads `.env` line-by-line and exports each `KEY=VALUE` into the
+process environment. `.env` is gitignored at the repo root, so your local path
+never gets committed.
+
+Packer picks the values up automatically through its `PKR_VAR_<name>` env-var
+convention; nothing about the `packer build` invocation changes.
+
+## One-time setup
+
+```powershell
+packer init .\windows-11.pkr.hcl
+```
+
+That downloads the `hyperv` and `vagrant` Packer plugins.
+
+## Compute and pin the ISO checksum (recommended)
+
+```powershell
+Get-FileHash $env:PKR_VAR_iso_path -Algorithm SHA256
+```
+
+Set `PKR_VAR_iso_checksum=sha256:<digest>` in `.env` and re-run `load-env.ps1`.
+Leaving it as `none` skips validation; fine for local builds but loses the "my
+ISO has not been swapped" guarantee.
+
+## Build
+
+```powershell
+packer build .\windows-11.pkr.hcl
+```
+
+Roughly what happens:
+
+1. Packer creates a Gen 2 Hyper-V VM (Secure Boot + TPM + 24 vCPU + 32 GB RAM
+   + 80 GB dynamic VHDX) attached to `Default Switch`. The build VM is
+   throwaway and intentionally claims most of the host for speed; the
+   runtime integration VM uses smaller defaults set in
+   `test/integration/Vagrantfile` (8 vCPU / 16 GB).
+2. It mounts the Windows ISO and a tiny `PROVISION` ISO containing
+   `cd/autounattend.xml` and `cd/scripts/oobe-enable-winrm.ps1`.
+3. Windows Setup performs an unattended install (Pro edition, generic
+   activation key) and creates user `vagrant`:`vagrant`.
+4. FirstLogonCommands enable WinRM (HTTP, basic auth) and set
+   `LocalAccountTokenFilterPolicy=1` so remote admin tokens are not filtered.
+5. Packer connects over WinRM and runs the provisioners in `scripts/`:
+   - `configure-os.ps1`         — UAC token policy, DiagTrack off, NTP resync.
+   - `disable-windows-updates.ps1` — fully disables WU and friends.
+   - `disable-defender-cloud.ps1`  — disables MAPS / cloud lookups.
+   - `install-vagrant-key.ps1`     — drops the vagrant insecure public key.
+   - `compact.ps1`                 — cleans caches, zeros free space.
+6. Packer shuts the guest down cleanly and the `vagrant` post-processor
+   packages the VHDX into `bootstrap-win11.box`.
+
+## Register the resulting box with Vagrant
+
+```powershell
+vagrant box add bootstrap-win11 .\bootstrap-win11.box
+```
+
+Then in `test/integration/Vagrantfile` set:
+
+```powershell
+$env:BOOTSTRAP_BOX = "bootstrap-win11"
+go run ..\..\test\integration
+```
+
+(or just edit the default in the Vagrantfile to `bootstrap-win11`).

+- **Run elevated.** `packer build` opens Hyper-V management APIs; non-elevated
+  shells fail with confusing "access denied" messages midway through.
+- **First build is slow.** Windows Setup + updates trimming + cipher /w on a
+  60 GB volume can take 45–90 min. Subsequent rebuilds reuse the parent VHDX
+  via linked clone and are much faster.
+- **License compliance.** The box uses the public KMS client setup key
+  (W269N-WFGWX-YVC9B-4J6C9-T83GX) to pick the Pro edition during install. The
+  resulting VM is not activated; for short-lived integration runs the eval
+  period is more than sufficient, but redistribute the box only under your
+  own licensing terms.
+- **25H2 OOBE.** The autounattend sets `BypassNRO=1` during `specialize`
+  because 24H2/25H2 removed the `BypassNRO.cmd` helper. If a future Windows
+  update changes the OOBE flow again, the symptom will be a hung
+  `vagrant up` waiting for WinRM; check by opening Hyper-V Manager and
+  looking for an OOBE screen on the VM console.
+- **Secure Boot.** Enabled (`MicrosoftWindows` template). Switch off in the
+  Packer source if you ever need to install unsigned kernel-mode drivers in
+  the box.

+  Unattend file for Windows 11 25H2 (Pro), Hyper-V Gen 2, UEFI + Secure Boot.
+
+  Goals:
+    - Fully unattended install on the only VHDX presented by the VM.
+    - Create local user `vagrant` (password `vagrant`) in Administrators.
+    - Skip every OOBE wizard page (including the network-required screen).
+    - Bring WinRM online with basic auth and unencrypted transport so Packer
+      and Vagrant can talk to the guest.
+
+  The BypassNRO trick is set in `specialize` rather than relying on the
+  removed BypassNRO.cmd script, so this works on 24H2/25H2.

+.SYNOPSIS
+    Installs HashiCorp Packer on Windows by downloading the release zip,
+    extracting it to Program Files, and adding that directory to the system
+    PATH.
+
+.DESCRIPTION
+    Winget does not publish HashiCorp Packer, so this helper does the install
+    by hand. It is idempotent: if the requested version is already installed
+    at the target location it just re-asserts the PATH entry and exits.
+
+    Requires an elevated PowerShell session (writes under Program Files and
+    modifies the machine-scoped PATH environment variable).
+
+.PARAMETER Version
+    Packer release to install (e.g. "1.15.3"). The download URL is computed
+    as https://releases.hashicorp.com/packer/<Version>/packer_<Version>_windows_amd64.zip.
+
+.PARAMETER InstallRoot
+    Directory under which packer.exe is placed. Defaults to
+    "$env:ProgramFiles\Packer". This directory is what gets added to the
+    system PATH.
+
+.PARAMETER SkipOscdimg
+    Skip installing the Windows ADK Deployment Tools (which provide
+    oscdimg.exe). Packer's hyperv-iso builder needs an ISO-creation tool
+    (xorriso, mkisofs, hdiutil, or oscdimg) on PATH when using cd_files,
+    so by default this script also installs oscdimg via the Windows ADK
+    bootstrapper with only the DeploymentTools feature selected (~70 MB
+    on disk).
+
+.PARAMETER AdkSetupUrl
+    Override the URL used to download the Windows ADK setup bootstrapper.
+    Defaults to Microsoft's stable fwlink for the Windows 11 ADK.
+
+.EXAMPLE
+    # Install the default version into "C:\Program Files\Packer".
+    .\install-packer.ps1
+
+.EXAMPLE
+    # Install a specific version.
+    .\install-packer.ps1 -Version 1.14.0

+    # Install Packer only; skip the Windows ADK Deployment Tools install.
