When installing JDK or JRE 6.0u3 msi and cab files are left behind in
C:\Documents and Settings\Administrator\Application Data\Sun\Java\jdk1.6.0_03
C:\Documents and Settings\Administrator\Application Data\Sun\Java\jre1.6.0_03
The size matches the JRE/JDK offline installation file (14mb/65mb).
This content of the JRE directory is being removed completely
when deinstalled. In the case of JDK a file named sb160030.cab (8mb) is left
behind even after deinstallation
However, while JRE/JDK is installed on a win pc, disk space is being wasted
unnecessarily. See also: 6422501
