The Microsoft Java Virtual Machine, or MS Java VM, is used to run Java applets that can be found on web sites. When you visit a web site that has a Java applet, the MS JVM will compile and execute that applet on your machine. Microsoft no longer supports the MS JVM and it has become obsolete. There have also been known security issues with un patched version of the MS JVM we advise that you remove it and install the safer SUN JVM as an alternative. If you have Windows XP SP1a installed on your computer, then you do not have the MS JVM installed on your machine.

 Procedures to follow

Start—> Run—>In the Open: field Type the following command click ok

RunDll32 advpack.dll,LaunchINFSection java.inf,UnInstall

The un-install process begins. Click Yes to confirm.


Reboot when prompted.

After the machine restarts, delete the following items:

the \%systemroot%\java folder

the file java.pnf from the \%systemroot%\inf folder

the two files jview.exe and wjview.exe from the \%systemroot%\system32 folder

the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Java VM registry subkey

the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AdvancedOptions\JAVA_VM registry subkey (to remove the Microsoft Internet Explorer (IE) options)

Microsoft Java is now removed.

Now you can download and install sun java from here
