uninstall - Are old Java(TM) 6 Updates safe to remove?

I have a PC that when you list the programs installed on it shows:

Java(TM) 6 Update 2
Java(TM) 6 Update 3
Java(TM) 6 Update 5
Java(TM) 6 Update 7
Java(TM) 6 Update 39

Is it safe to delete all but the most recent one?

Answer

Yes you can remove them, it is extremely rare for a program to need a old version of java.

In fact the "safe" thing to do is uninstall 6 update 39 too and install the most current version available from the website.
