how to revert back to java 6?

Question

I upgraded to java and set to following advance envirnment variables frrom windows UI(not by command prompt)

JAVA_HOME = C:\Program Files\Java\jdk1.7.0_51
PATH = %JAVA_HOME\bin%

when i do java - version it reflects the right java version as "1.7.0_51"

but when i try to revert back to jav java 6 after reverting java_home (from windows UI )back to

JAVA_HOME = C:\Program Files\Java\jdk1.6.0_43
PATH = %JAVA_HOME\bin%

i opened new commad prompt but java - version still reflects the java version as "1.7.0_51"

should it not reflect java version as.6.0_43 ? Can't i go back to java 6 just by reverting java_home?

Answer 1

There is probably a java.exe in your C:\WINDOWS\System32\ folder leftover from the previous installation. Replace it with the one in C:\Program Files\Java\jre6\bin.
