I'd love for Windows to be more secure and stable. What I don't love is Microsoft's pathological need to change the control interface on _every_ single new release. This is such a pain in the neck. Windows 2000 had it mostly right: instant access to network and most-often-used control panel items. XP came along and decided it needed to "group" these - burying the ones used most (like desktop resolution and network settings) under more layers. Vista and 7 only made this worse (at least 7 has the neat registry hack to expose ALL the control panel tools). Now more of the same.

If there is one thing Microsoft should have learned from Google and Apple with regards to a touch device, it is that you need to make it easy to access. Burying these deeper and deeper just frustrates admins and users who have to search and search to find the tool they need.
