Replace Microsoft JVM with Sun Java Runtime
Microsoft’s Java Virtual Machine (JVM) contains several flaws, and with WinXP SP2 the JVM have been removed. If not using WinXP SP2 then one should consider to remove the JVM manually and replace it with the Sun Java Runtine. Test Java Runtime Engine.
Note Microsoft have withdrawn their removal tool for public download, instead one have to contact Microsoft to acquire the tool. Majorgeeks.com is friendly enough to provide a mirror of the tool.
