A google search about the fish; Under Water screensaver,
show me that a lot of others, also got some problems
with that old screensaver, so here is a batch file:

@echo off
echo.
echo. Press any key to copy the Underwater Screensaver.
pause > nul
cls
echo.
copy "Underwater.scr" C:\Windows\System\
copy "Underwater.dll" C:\Windows\System
copy WL32DLL.DLL C:\Windows\System
copy WILDLB32.DLL C:\Windows\System
echo.
echo. In WinXP, right click the file:
echo. Windows\System\Underwater.scr
echo. and select Install from menu.
echo.
echo. Press any key to open the folder, C:\Windows\System
pause > nul
explorer "C:\Windows\System\"
cls
