I tried it a couple of years ago on my old Win7 machine, found it unstable and caused me BSOD too many times, as I recall not just at system boot. As other users in this thread have documented, it is not without its problems. Seems to me you need to be very confident with your IT skills to safely use it. I am not that confident, which is why I installed it in the first place. It caused me too many headaches in my normal working routine, so it was uninstalled after a couple of months.
