Out of interst, what do people install java for on windows 7 nowadays? Are there specific sites and apps which require something like it to be installed.
I have 7 since launch, purposely never installed java, thus have never updated it, or I hope been subject to issues arising from its installation.
I am unaware of internet sites that don't work for me when running ie8 in protected mode from a user account with UAC on.
What am I missing out on?
It's a common misconception, but Javascript is not Java. The common browsers all have Javascript interpreters built-in, it's not something you install. If you want to see the web without Javascript you can disable it in your Internet Options/security tab.
Some sites do require actual Java which will download the bytecode and run it on your machine in the browser window, but you don't see them very often.
