echo.

echo                  GameBar, Widgets
echo                  (frees RAM and CPU from background noise)
echo.
echo   Windows Update : Service stopped + disabled temporarily
echo                    (prevents mid-game update downloads)
echo.
echo   Defender     : Real-time scan disabled temporarily
echo                  (eliminates game file scanning overhead)
echo.
echo   TCP Tweaks   : TcpAckFrequency=1, TCPNoDelay=1
echo                  (reduces network latency / ping)
echo.
echo   Process Priority : Win32PrioritySeparation=38
echo                      (more CPU time to foreground apps)
echo.
echo   GPU Priority : Games task = High scheduling category
echo                  (Windows schedules GPU work sooner)
echo.
echo  RESTORE (Option 2):
echo  --------------------
echo   Reverts ALL 6 changes to exact Windows defaults.
