    on my laptop I have many versions of .NET installed.
    I have .NET 1.1, .NET 1.1 Hotfix (both 1.45GB), and .NET 2.0 (slightly less than 100MB). Do I have to keep the 1.1s? also what about Java? I have SE Runtime 6 Update 1, 2 Runtime Environment SE v1.4.2_12, 6 Update 2.

    These are taking up a bit of space on my HDD so I was wondering which would be OK to remove. Thanks

    Only if you're using .NET applications that specifically require 1.1 (2.0 doesn't include 1.1, they can be installed in parallel).

    See above. Do you use any Java applications that require a specific, older JVM version? Keep in mind that most people probably don't use any Java applications at all, just browser applets (and even those seem to be pretty rare these days), so general advice is to have only the latest version installed. That would be JRE 6 Update 7, and you should make sure to uninstall all older versions manually (the installer won't update/remove them) because the older ones usually contain security vulnerabilities.

    You might want to double-check to make sure you don't have any apps that depend on any of the .NET frameworks before you delete them. First I'd check on Microsoft's website to see what they have to say about whether or not it's safe to uninstall/delete these frameworks, second I would be inclined to use Sysinternal's Dependency Walker to double check on the dlls for the earlier frameworks to see if you've got any apps that might depend on those earlier frameworks.
