Well I would look for drivers if they are needed but I see if I do a search on Blue Yeti that someone posted they are having issues with it in Windows 8.1. So that points to it may need drivers or it lists all these OS's like XP & 8.1. Well XP is basically a 32 bit OS and 8.1 is 32 or 64 bit. I imagin the Tech Preview is 64 bit so maybe it requires a 32 bit OS?
