As has been said, the real question is are your hardware devices, particularly audio interfaces (with ASIO drivers) compatible. If you are running Win 8-8.1 they are likely to be fine. If you are running Win 7, they may be OK, but you should check with the manufacturer to see if they have Win 8 drivers available. If you are running XT and the manufacturer's support stops there, you are probably out of luck... or have a good incentive to buy a newer, probably better interface. BIAB itself should run fine. Mine does. The program itself does not run all that much better than on Win7, but I like Win10 better generally and I hated Win8.

I am the sort of guy who can't resist trying the latest stuff, but if you are not that sort of guy, you might hold off the upgrade for a few months until you can learn more about the compatibility of your system and Win10 settles in.
