I have found that it could be a problem in solr.cmd.
It works after I replace this line in Solr 5.3.0
IF NOT "%EXAMPLE%"=="" goto run_example
With this segment of the code from Solr 5.2.1
IF "%EXAMPLE%"=="" (
IF NOT "%SOLR_HOME%"=="" (
REM Absolutize a relative solr home
IF EXIST "%cd%\%SOLR_HOME%" set "SOLR_HOME=%cd%\%SOLR_HOME%"
)
REM Otherwise SOLR_HOME just becomes %SOLR_SERVER_DIR%/solr
) ELSE IF "%EXAMPLE%"=="techproducts" (
mkdir "%SOLR_TIP%\example\techproducts\solr"
set "SOLR_HOME=%SOLR_TIP%\example\techproducts\solr"
IF NOT EXIST "!SOLR_HOME!\solr.xml" (
copy "%DEFAULT_SERVER_DIR%\solr\solr.xml" "!SOLR_HOME!\solr.xml"
)
IF NOT EXIST "!SOLR_HOME!\zoo.cfg" (
copy "%DEFAULT_SERVER_DIR%\solr\zoo.cfg" "!SOLR_HOME!\zoo.cfg"
)
) ELSE IF "%EXAMPLE%"=="cloud" (
set SOLR_MODE=solrcloud
goto cloud_example_start
) ELSE IF "%EXAMPLE%"=="dih" (
set "SOLR_HOME=%SOLR_TIP%\example\example-DIH\solr"
) ELSE IF "%EXAMPLE%"=="schemaless" (
mkdir "%SOLR_TIP%\example\schemaless\solr"
set "SOLR_HOME=%SOLR_TIP%\example\schemaless\solr"
IF NOT EXIST "!SOLR_HOME!\solr.xml" (
copy "%DEFAULT_SERVER_DIR%\solr\solr.xml" "!SOLR_HOME!\solr.xml"
)
IF NOT EXIST "!SOLR_HOME!\zoo.cfg" (
copy "%DEFAULT_SERVER_DIR%\solr\zoo.cfg" "!SOLR_HOME!\zoo.cfg"
)
) ELSE (
@echo.
@echo 'Unrecognized example %EXAMPLE%!'
@echo.
goto start_usage
)
Could there be some issues with this line [IF NOT "%EXAMPLE%"=="" goto
run_example] in Solr 5.3.0 (line 601 in solr.cmd)?

Edwin
