I have a 2i2 focusrite and I upgraded to windows 10.  There are no drivers, none period. doesn't work.  I will be back to windows 7 by morning if I don't have an answer soon. 

I'll go Mac before I even consider Windows 10. But would rather go Linux before Mac... Does Sonar even have a 'nix option?

I'm having some issues with my 18i20 and Windows 10, but the drivers recognize the interface.  I was checking out the Focusrite beta driver page and saw something about problems with the 2i2 and Windows 10 and the beta driver may offer a solution.  Here's a link to the page: http://beta.focusrite.com/
Scroll down to the drivers 3.2.2

Also, I ended up rolling back to Windows 7 so I have something working, but I set up a dual boot with Windows 10 to see if I can resolve the issue.  It seems that if you want to keep current with the Sonar updates, Windows 10 is inevitable.  If you have enough hard drive space, it might be worth setting up a dual boot system.

I'm using a Scarlett 2i4 on Windows 10 x64 with no issues here.
The USB driver 2.5.1 works fine with Windows 10

It also says that the 18i20 works with 1.8, but it doesn't work (well) for me.  It's very unreliable.

no more koolaid please!  This forum is amazing.  I am already back to windows 7-- Yeah!  everything works- I have drivers I have addictive drums (another problem).  I do a lot with this machine (too much).  I run most of my business applications, my MS office applications, and sonar with about 60 projects.  I did this upgrade this morning and all day I was like- why?  bottom line- if I have to do something like this with this machine where it does all it does I will hire a tech for about 2-300$ to do it all.  wow, you guys are great!  thanks and thanks

Same here, 2i4, W10, no probs.

 I guess I will move out of the Focusrite fan club.  This company is often quite good when it comes to driver support. There really shouldn't be any issues with a USB 2 audio interface.  Windows 10 should be able to use the W7/W8 drivers with no issues.

It won't be much different. W10 is going to be an evolving OS.  People went through hell with El Capitan. I got emails warning Mac users to avoid that update until developers could make their stuff work. Linux will always be a dead end and only the delusional ones will try to prove everyone wrong.
 
 There will be advantages to Windows 10 as there will be support for new lower latency platforms.
