Each time I install JDK/JRE I feel that my system has a bit more overhead to it and it feels a bit "heavier" than before. Are there any services that startup with JDK or Java related that get installed to my system and if they do, is there a way to disable them?

Thanks!

This question makes no sense. The services that are installed are only ran when they are needed. My guess the "heavier" feel, whatever that means, it just a imaginary loss in performance. –  Ramhound Mar 28 '12 at 12:01

One resident process that is installed alongside the JRE is the Java Updater.

The linked page also shows how to disable it:

III. Configure Java Updates

Automatic Update Feature

  1. Click Start > Settings > Control Panel (For Windows XP)
    Click Start > Control Panel (For Windows Vista and Windows 7)
  2. Double-click Java icon. The Java Control Panel appears.
  3. Click the Update tab
    Note:
    • The Update tab may not be available if your network administrator has disabled the Java Update feature during installation.
    • If you are not logged in to system as administrator then options to change Java update notifications will be greyed out and user will not be able to change it.
  4. To enable Java Update to automatically check for updates, select the Check for Updates Automatically check box.
  5. To disable Java Update, un-select the Check for Updates Automatically check box.

Obviously, it will also install ActiveX components and such, which might have a minor impact on overall system performance. But I don't think they should be noticeable. And if you wanted to get rid of those, then I don't think the JRE will still work.

I always have issues on Windows Machines used for developing java applications. I think I'll just use Linux for my Java apps cause I simply don't trust the way MS WIndows work.. –  polyglot Mar 28 '12 at 15:25

Run msconfig from the 'Run..' prompt, go to startup, and see if anything in there is starting that you don't need. You can turn pretty much everything off, except for things like firewalls and virus scanners. You might see JDK/JRE in there, but I doubt it.
