Help Needed!! Micros WS6 610 Help Needed!! Micros WS6 610 Tsmtbo2011 (Vendor) (OP) 3 Jun 21 08:51 Does anyone know how to change the WS6 610 mainboard from Windows 10 to be able to run Win 8.1? I dont have any of the WIN 8.1 boards left to compare switch settings etc. I'm almost certain the boards are the same but it will not run a Win 8.1 HDD. Thanks in advance. RE: Help Needed!!
