10 runtime updates

I have about 10 updates showing in my install programs window, using around 1 gig of hardrive space. Is this really necessary? Can I delete some of these since they are taking up so much space?

You may not need all of them, but be careful about deleting them. Some applications are specific with which version they are certified with. Just keeptrack of what you have, and if any app starts to break, re-install those again.

Wouldn't it be better to have one installed version rather than several? I recieved an update to java today, making my total installed updates 11.

Doesn't this seem a little much?

Each update is cumulative of all bug fixes to date. However, application vendors

can specify which specific version that their app needs. So this isn't a problem

with your update, or the version of JRE you just installed. It's an issue with

application vendor hardcoding the version of JRE they need. This is why you

need to be careful about removing older versions.

Here's a more detail readup:

(read first question)

And if you evern need older version, read later question about how to obtain

those.

Hope this helps.
