File	Summary / Findings
windows/installer/defyx_vpn.iss	Defines the installer. Moderate (2 votes): Startup registration does not quote the executable path, breaking launch from paths containing spaces.
scripts/setup/version.sh	Removes MSIX version updates.
pubspec.yaml	Removes MSIX configuration.
pubspec.lock	Removes MSIX-related dependencies.
.github/workflows/windows.yml	Builds and uploads the EXE installer.
.github/workflows/build.yml	Formatting-only workflow changes.
.github/release_message.md	Updates the installer link. Moderate (2 votes): Existing releases may retain a stale .msix link because the release body is not regenerated.

• The app creates HKCU\Software\Microsoft\Windows\CurrentVersion\Run\DefyxVPN when launch-on-startup is enabled (windows/runner/registry_manager.cpp:23-35), but this installer has no uninstall cleanup for that value. Uninstalling after enabling the option removes the executable while leaving Windows to try launching the missing path at every login. Add an uninstall-time deletion for that exact Run value.
