FWIW
I have the latest Win 10 Preview version 10130 installed. Testing, Sonar Platinum and my Roland Studio Capture work OK in Win 10. I just installed my Frontier Tranzport, in a Windows 7 compatibility mode, and it checks out OK in Sonar. The last drivers issued for the Tranzport were Vista drivers.
Microsoft must be getting close to the "final" Windows 10 version. I have a triple boot system, Win 7, Win 8.1 and Win 10 Preview. In all prior Win 10 Preview versions, in the OS boot selection menu it was listed as "Windows 10 Preview". With the latest 10130 version it is now just listed as "Windows 10".
