| `setup-windows.bat` | Entry point. Runs the winget installs, then the non-elevated script, then launches the elevated half and prints its log. |
| `setup-windows-no-uac.ps1` | The non-elevated, per-user half: WinMerge and BinSkim on the user `PATH`, and the global git config (identity, plus `core.sshCommand`). Can also be run directly from an ordinary prompt. |
-| `setup-windows-with-uac.ps1` | The elevated half, started via UAC by the batch file. Enables `ssh-agent`, installs and starts OpenSSH Server, installs `rsync.exe` to the machine `PATH`, then installs Visual Studio 2022 Community with the required components, the WDK, and the Windows Performance Toolkit. Can also be run directly from an Administrator prompt. |
+| `setup-windows-with-uac.ps1` | The elevated half, started via UAC by the batch file. Enables `ssh-agent`, installs the OpenSSH Client and Server capabilities and starts `sshd`, unpacks the `rsync-windows` release zip for this architecture (`rsync.exe` plus the `ssh.exe` it runs) into `C:\Tools\rsync` on the machine `PATH`, then installs Visual Studio 2022 Community with the required components, the WDK, and the Windows Performance Toolkit. Can also be run directly from an Administrator prompt. |
## Usage
a profile. Key auth needs `~/.ssh/authorized_keys` ACL'd to just you and
`SYSTEM`; accounts in the Administrators group use
`C:\ProgramData\ssh\administrators_authorized_keys` instead.
+- **rsync brings its own `ssh.exe`.** That release ships as one zip per
+ architecture — `rsync-windows-x64.zip` / `rsync-windows-x86.zip`, each holding
+ `rsync.exe`, an `ssh.exe`, `COPYING.txt` and `NOTICE-ssh.txt` — and the
+ elevated half picks the zip for the OS bitness, verifies it against the
+ published `.sha256`, and unpacks the pair together. Together is the point:
+ `rsync.exe` prefers an `ssh.exe` sitting in its own directory, and the release
+ builds one because the client Windows ships reads its stdin 3 KB at a time,
+ which holds a transfer *from* the box at ~17 MB/s however fast the link is.
+ Nothing else about it differs — same `~/.ssh`, same `ssh-agent`, same
+ `known_hosts` — and a bare `ssh` still resolves to the in-box client, which
+ sits ahead of `C:\Tools\rsync` on the `PATH`. It links against the
+ `libcrypto.dll` the **OpenSSH Client** capability puts in `System32` (Windows'
+ own LibreSSL, which uses AES-NI) and ships no copy of its own, so the elevated
+ half installs that capability first and falls back to `rsync.exe` alone,
+ warning, on an image that will not offer it.
+- The `rsync` download follows the `releases/latest/download/` redirect rather
+ than the GitHub API: unauthenticated API calls are rate-limited to 60/hour per
+ IP, which a provisioning run behind a shared NAT can genuinely exhaust. To hold
+ a box on a known build, pin the tag in `$RsyncUrl`
+ (`.../releases/download/<tag>/<asset>`) instead.
