Installed Windows 10 this morning... The 700 drivers didn't work out so well!  Uninstalled the drivers, reinstalled... still hasn't connected right... it's stalled at the ... the driver will install automatically" window.  The device driver has the exclamation points and the VS-700 is showing up under "Other devices". 
I have all other sound devices disabled ....
 
So from my perspective... be careful my friends!!

There's a tricky workaround that some people used to get the v700 working in Windows 8, before the driver update, that might work the same for Windows 10. It's a bit techy, so only for the brave: http://www.alphr.com/blog...s-to-work-in-windows-8

John T - Thanks for the link.  I was able to use the Win 8.1 driver with the help of that article.  You do have to disable driver signatures, which is pretty easy to find in windows 10.   I modified the VS100 V202 drivers with notepad and disabled driver signatures.  The driver installed and my VS100 is working again.
 
You need the find the [Manufacturer] line in the RDIF1099.inf file and modify it as follows
;---------------------------------------------------------------;
[Manufacturer]
%MfgName%=Roland,NTamd64.6.2,NTamd64.10
;[ControlFlags]
;ExcludeFromSelect=*
[Roland]
;; Windows7 - Windows XP 64
;; not supported
[Roland.NTamd64.10]
;; Windows8
%RDID0099DeviceDesc%=RDID0099Install, USB\VID_0582&PID_00EB ; VS-100
[Roland.NTamd64.6.2]
;; not supported
;===============================================================;
 
Note the bold text, which are the only lines I changed.
 
Time will tell as to how stable it is, but it's a work-around for the time-being.  I don't think I'd recommend anyone running a pro studio to depend on this as a reliable fix...
 
Cheers,

Folks... it is easy to roll back to Windows 8.1 if you find yourself in the same boat as I was with the 700 drivers ()  I'm now back to where I was... waiting for Roland to bring us new drivers!

Sorry here's a url:  
 

Won't let me put the url in... just google "uninstall windows 10 tom" and the first hit will get you there.
 

I'd try the INF hack before rolling back, personally...  Windows 10 is pretty good, imho.

Ah, so that works.

I'll admit to being a cowardly soldier, huddling at the back of the line here, but if that method works, I think I'll do the upgrade. Just too busy with work right now to chance it not working. So thanks to you for going first
:)

 I've messed around with it over the pre-release period on other people's computers, and I like it a lot. As long as I can get all my audio stuff working ok, I definitely want to upgrade. I think it's a really impressive update, in design and usability terms.

I'm digging it.  Love the window snap features and the multiple desktops.  (Yes I know it's been standard in Linux & MAC OS for years)
 
So far all seems stable with Sonar X2 & my trusty VS-100.  The only thing I haven't been able to get working is the control surface link on the VS100.  That may be a deal-breaker for the 700 owners...
