It does. Recently, I had to make a little clean-up on some of our machines here at work and found lots of entries for different versions of the JRE on the "Add/Remove Programs" applet in the Control Panel. I scratched the back of my head for a moment and then removed the old ones... And yes, it still worked properly afterwards! 
Yes, it seems that the JRE Updates install full versions
so they can be independently removed. I've seen as many as 11 different Sun JREs installed.
In a few cases, older versions, as far back as ver 1.3 are needed to support apps that won't work reliably with anything newer but, for a ( growing ) handful of users, once Java errors start happening, nothing but a re-imaging will resolve the problem.
So, I was hoping that someone could recommend an alternative JVM with in IE browser plug-in. ( Regrettably , some of the organisation's intranet sites don't work properly with Firefox or Opera )

I do corporate desktop support for a company that loads
a custom install of XP and that also relies heavily on Java with IE for their Intranet apps.
Lately, we've been seeing a lot of problems regarding the JVM loading that cannot be fixed by removal / reinstallation.
When IE is messed, we can fall back to Firefox until the user can turn in their laptop to onsite support but I haven't found any alternative JVMs that include browser plugins.
Do anyone know of any?
