Java Runtime Environment is a must-have plugin for various web-applications, this powerful cross-platform web-application architecture is also one of the most exploited ones and can pose serious security risks if not updated regularly. The problem is, even if you have the latest updated Java version with new features, vulnerability fixes and performance improvements older version may still be there on your computer which can get compromised. We shared the JavaRa utility earlier, which takes care of this security risk allowing users to remove older Java versions from their computers. Oracle has now made available an online Java applet which allows users to check for older Java versions on their computers and uninstall them.

You could encounter the "Windows Java Installer Error 1723" during JRE installation, chances of this error are even higher when trying uninstallation of a newer Java version followed by installation of an older version. Things get really annoying when the solution provided (deletion of registry key) at Java and other websites/forums fails to solve the issue. After a lot of hit and trial, I finally got it solved as instructed ahead.

Java is a versatile powerful programing language allowing users to enjoy interactive web-content, powerful multi-platform applications and much more on their computers, Java Runtime Environment (JRE) allows users to run applications and applets written in Java on their computers, being a powerful and widely used programming language Java is often a primary target for Malware authors who use vulnerabilities in JRE to spread the infection, Java advises users to always have the most updated version of Java Runtime Environment (JRE) on their computers to enjoy latest feature additions, better performance and fixed security vulnerabilities, however at the same time Java updater retains older versions for backward compatibility, and if you don't want this, open-source utility JavaRa is the solution, the portable utility lets you automatically remove all the older Java Runtime Environment (JRE) versions and update to the latest with ease.
