Windows and Linux/Unix are so fundamentally and thoroughly different that this is like asking "Which parts of a helicopter do you prefer over a jet-ski?" You could say that Windows is an instance of "Windows-like" operating systems and Linux is an instance of "Unix-like" operating systems. So features of Windows are really features of the "shape" or "likeness" of Windows. And ditto for Linux. If you're designing an OS from scratch, you'll find many points where you must choose between "Windows-like" or "Unix-like". The Windows-like features fit together naturally, and the Unix-like features fit together naturally. This even extends to the development model. A corporation will find it easier to create a Windows-like OS than a Unix-like OS. But a distributed group of developers will find it easier to make a Unix-like OS.
