rem -----------------------------------------------------------------
rem Restore Windows networking stack settings toward stock defaults.
rem Target: Windows 8 / 8.1 / 10 / 11 and newer, with runtime feature

echo =====================================================================
echo.
echo This script is intended to undo common network "optimizer" / tweak changes.
echo.
echo It will reset as much of the Windows networking stack as can be safely and
echo consistently reset from batch on Windows 8/8.1/10/11 and newer, including:
echo.
echo   - Winsock catalog and TCP/IP stack state
echo   - IPv4 and IPv6 user-configured stack settings
echo   - TCP global / heuristics / security / supplemental template settings
echo   - UDP global settings if the local Windows build supports them
echo   - Dynamic client port ranges for TCP and UDP, IPv4 and IPv6
echo   - Teredo / ISATAP / 6to4 / IP-HTTPS state where supported
echo   - WinHTTP proxy and portproxy configuration
echo   - Common registry tweaks used by "gaming" / "latency" scripts
echo.
echo Important:
echo   - A backup is created on your desktop before changes are applied.
echo   - Because Windows IP reset commands restore user-configured settings,
echo     static IP, DNS, gateway, WINS, and some route settings can be cleared.
echo   - The PC will restart automatically after you acknowledge the final prompt.
