There is no registry in Linux so there can't be a registry editor.

Hardware panels and task managers do exist (and they come in more windows-like distros), they're just different to Windows ones. I do concede that hardware management in Windows is much easier.

Task manager for Windows absolutely blows though. It doesn't show real data, just estimates that sometimes are wildly wrong.

Well Linux doesn't have a registry, so an editor would also not exist, to be fair.

I disagree on the task manager. I like the KDE Plasma monitor application for instance. Very convenient way to sigterm or sigkill.
