It's possible to move required Windows folders to a separate drive during installation. For the past 10 years, I've had my Users directory on a hard drive, leaving everything else on an SSD. As long as I don't install too many things on the SSD (like games), I've never had to worry about where everything is. Although there's warnings about 'this isn't supported', I haven't been burned.
