As the gadget nerd I am, when running Windows 10 Insider in the fast ring can give some challenges.
The build 17084 that come out yesterday gave me lots of trouble.
So today I had to rollback to get my Senneheiser MB 660 UC to work again.
So now I am running build 17074 after a quick restore. Hope the next version will be better :-)
Have a great one.
