I really wish they would re-work the system from the ground up. The bottomless backwards compatibility is such a drag at this point. Just include a very good XP virtual machine with it... To me windows is such a mess, with settings, services, options, updates, capabilities spread all over, sometimes arbitrarily, a lot of it because of legacy It boots for ages, runs slow, insists on doing stuff behind my back, there is so much opaque problems

I run Ubuntu now and yes, there are problems that go with that, but surprisingly hardly any with the OS itself (my arduino refuses to sync with usbtty, one or two odd, but harmless bugs, some really annoying ones Octave cant print most graphs(if they have too much dataon them) to anything different than pdf) - the core is solid, able to work with most cases straight away. Windows?(I work with win 7) You want rar? How about converting .xps to anything useful? Just from the top of my head

Disentangling some stuff(yay, regular start menu updates! Does it even matter?) from the piecemeal core won't fix the most glaring problems, IMO
