Uninstall all Java in batch

I usually have Java 6, 7 and 8 installed on my (Windows) machines, but whenever an update comes out, I have to manually, one-by-one uninstall them from the control panel. For 64 bit systems, this is doubled. However, I found a command which can do this automatically and for multiple versions at the same time.

You only need to create a batch file with the following content, and run it as administrator:


wmic product where "name like 'Java(TM) 6%%'" call uninstall /nointeractive
wmic product where "name like 'Java(TM) SE%%'" call uninstall /nointeractive
wmic product where "name like 'Java 6%%'" call uninstall /nointeractive
wmic product where "name like 'Java 7%%'" call uninstall /nointeractive
wmic product where "name like 'Java 8%%'" call uninstall /nointeractive
wmic product where "name like 'Java SE%%'" call uninstall /nointeractive

Java security update

Java security has been improved again. I strongly recommend updating your Java to 7u9. In addition, if you have Java 6 installed as well, update it to 6u37.

Recent Java vulnerabilities

It seems Java is under more scrutiny than before. Several critical vulnerabilities have been identified in the last few months. Since Open-IG requires Java, these events may concern you.

You may want to disable Java browser plugins until the situation is resolved. I expect Firefox to release a killbit for up to versions 1.7u7 soon. Chrome usually asks for your permission, therefore, don't let any untrusted site run any Applets.
