but they work on Win10 with older drivers.

I tried using the old Presonus FirePod Windows 7 drivers on Windows 10.  They would only give me 2 channels (Yes, I did try "compatibility" mode. It simply would not work...

Did the W10 upgrade last night ( Win7 64> in place upgrade to Win10)
No issues; surprisingly effortless with exception of having to reauthorize XLN Addictive Drums 2.
Otherwise, most of my settings and customizations were in tact and all seems to work well.
I was overly concerned about the switch-over. Hope it goes as smoothly for others.

On my PC Win 10 works quite good.
