An window 10 driver for ua25ex is released by roland. Just connect your PC to internet with ua25ex plugged in, the driver download is automatic. There is an earlier thread about win 10 driver for ua25ex about a week ago. Alternately you can go to device manager and right click ua25ex, select update device from the drop down menu. Cheers.

I just installed Win 10 and the UA25-EX works fine in advanced mode.  hooray!

You have 30 days to roll back to your previous OS from Windows 10...

Is it because they have released drivers that are now automatically recognised in Win 10?   I wonder how likely it is my UA-25 can use  UA-25EX drivers for Win10.

I uninstalled the device through device manager, removed ,usb cable, restarted windows, this time windows saw it, and installed it in sound and video devices, and cakewalk also discovered it, but only as an output device (Speakers),
and no input device.  So I uninstalled it again, downloaded Vista64 bit (As I saw it on some site, cant remember) drivers from Roland site, reconnected USB cable to Edirol ua25, when it asked for drivers, pointed at the unzipped folder for the Vista 64 bit drivers, then opened cakewalk, """"""""Wow""""""", the input device is now also Edirol 25, and an input from my mic, moves the levels, and I have signal coming through to my cakewalk, so I assume, I can record now. It is also with advanced button pushed in! So windows 10(64) drivers for Edirolua25 are the same as vista64
