Actually, the reason is opposite in my case. I keep nothing of value on C: simply because once every few years the current version of them Windowses will crash, and I'll lose the registry, sometimes the whole partition. Whenever moving to a new set of disks, I give some space to the OS and to those apps which don't ask where to install and pretty much write that off. That's not my space, that's Redmond tax.
