I like these updates, but the one issue that still persists are the duplicate programs. There is a settings app and the control panel, and Microsoft needs to only have one setting app for Windows (2 gets confusing).
Unless I'm just not seeing them, there are still features in the control panel of Windows 10 that aren't present in the metro-style Settings, such as most of the advanced power plan settings.
I agree that there should only be one of these programs. Having two repositories containing (hopefully all of) the same things is wasteful.
Right now, my biggest complaint with Windows 10 is probably the lack of proper control over Windows Update. I couldn't figure out how to stop it from restarting without my permission, let alone let me choose what updates to install and when to install them. Right now, I've only managed to force it to let me stop the automatic restart using a command line workaround.
