+# Windows Setup by Paravis — C++ port
+
+Native Win32 port of `Windows_installer_NEW\setup.au3`.
+
+## Build
+
+Requirements: Visual Studio 2022 (Desktop C++) and CMake 3.20+.
+
+```bat
+build.cmd
+```
+
+Outputs:
+
+```
+build_x64\Release\setup_x64.exe
+build_x86\Release\setup_x86.exe
+```
+
+The executables use a static CRT, are GUI subsystem, and use the same
+`asInvoker` manifest / Common Controls 6 as the AutoIt builds.
+
+## Preview
+
+- `setup_x64.exe /preview` or an executable named `setup_preview*.exe`
+  starts preview mode: fixed 307×259 position, all buttons enabled, no
+  `src_*.exe` helper, preview wallpaper.
+- The ported `setup_preview.exe` in `..\Windows_installer_NEW` is the x64
+  build used this way.
+
+## Deployment
+
+On a PARAVIS flash the two Windows Setup WIMs are:
+
+- `\efi\Paravis\Boot\ws64.wim`, image 1, `\Windows\Setup.exe` — x64 build
+- `\efi\Paravis\Boot\ws86.wim`, image 1, `\Windows\Setup.exe` — x86 build
+
+`Winpeshl.ini` in both WIMs already launches `%SYSTEMROOT%\setup.exe`.
+The launcher starts the real setup from `X:\sources\setup.exe`.
+
+The window is layered with color key `0xABCDEF`. The Montserrat fonts are
+embedded as RCDATA; the 1024×768 wallpaper is embedded as a lossless PNG and
+decoded with GDI+ at startup. This keeps each executable around 1 MB.
+The UI is the same 376/410/360-wide layout as the AutoIt version, with native
+buttons. GDI+ and ole32 are standard components of the Windows Setup boot.wim
+(verified in the target image).
+
+## Behaviour
+
+- Searches all drives for `\WindowsESD\NOT.DEL` or
+  `\efi\Paravis\Windows\NOT.DEL`.
+- Warns and exits if both image folders are present.
+- Finds `\efi\Paravis\Boot\NOT.DEL` for `src_x64.exe` / `src_x86.exe`
+  and Total Commander.
+- Uses `%WINDIR%\SYSWOW64` to select the x64 UI; `firmware_type` selects
+  Legacy vs UEFI for the x86 UI.
+- Builds the same `X:\sources\setup.exe /installfrom:... /m:... [/unattend:...]`
+  command lines as AutoIt.
+- Disables Windows buttons when the corresponding ESD image is missing.
+- Reboot button exits the launcher (the WinPE startup script performs the
+  reboot).
+- Debug log: set `PARAVIS_DEBUG_LOG=1` to write
+  `%TEMP%\winsetup_cpp_debug.log`.
