Has anyone been brave enough to attempt this with W10 technical previews yet?
 
EDIT: well, what a great thread. All the hard work done by MackTheKnight and dustriplin. Eventual solution copied below. Follow these steps to the letter, and all will be well.

IT WORKED!!! I have the 700 running right now in Windows 10.  Still testing it for stability and have a few things I have yet to install... but so far so good.
 
Process I used (Many thanks to MACK for getting this far )  Will be a bit loquacious here, because I'm still not exactly where in this process I went wrong in my first attempt.  I took the liberty to go back up and copy much of Mack's helpful suggestions so we have everything in one place now.
 
My current system is an INTEL(R) Core(TM) i7 CPU  [link=mailto:920@2.67]920@2.67[/link]GHz with 9.00 GB (64-bit Operating System, X64-based processor) running Windows 8.1.  I'm running a fully updated version of Sonar Platinum Producer.
 
While still in Windows 8 I did the following steps (1-4):
1.  I uninstalled my 700 drivers and made sure my 700 was turned off (but didn't unhook it)
2.  I transferred my copy of the 700 V2.02 to the desktop.
3.  in the  \vs700_w81d_v202\vs700_w81d_v202\Files\64bit\Files\ folder I found the  RDIF1089.inf file and opened it in Notepad.  
4.  I cut and copied the following (from Mack's work above) into the [Manufacturer] section:
;---------------------------------------------------------------;
[Manufacturer]
%MfgName%=Roland,NTamd64.6.2,NTamd64.10
;[ControlFlags]
;ExcludeFromSelect=*
[Roland]
;; Windows7 - Windows XP 64
;; not supported

;; Windows8
%RDID0089DeviceDesc%=RDID0089Install, USB\VID_0582&PID_00FD ; VS-700
%RDID0090DeviceDesc%=RDID0090Install, USB\VID_0582&PID_00FE ; VS-700 M1
%RDID0091DeviceDesc%=RDID0091Install, USB\VID_0582&PID_00FF ; VS-700 M2

%RDID0091DeviceDesc2%=RDID0091Install, USB\VID_0582&PID_0101 ; VS-700 M2
[Roland.NTamd64.6.2]
;; not supported
;---------------------------------------------------------------;
5. Installed Windows 10 (At the end I had a NVIDIA GeForce GTX 650 card that did not load up so my video looked wonky.  Also the second monitor isn't working because of this... but I'm ignoring this for now)
6. Went into the Device Manager (right click the Microsoft logo on the bottom left and open the Device Manager) and disabled everything that was in the sound, video, and game controllers folder (I have an onboard audio, MOTU 2408 PCI card, and NVIDIA options here that you might not have)
7. Turned off the driver-signing signatures:  I'll outline the procedure here for Windows 10.
-Find the power options on the Start Menu (the microsoft symbol in the bottom left).
-Hold down the SHIFT key while you click Restart.
-Once your computer has rebooted you will be able to choose the Troubleshoot option.
-Head into Advanced options.
-Head into Startup Settings.
-You will select the restart option.
-After it restarts again, you will be given a list of startup settings. The one we are looking for is “Disable driver signature enforcement”. To choose the setting, you will need to press the F7 key.
-Your PC will then reboot and you will be able to install unsigned drivers without any error message.
8.  Run the setup.exe from the VS700_w82d_v202 directory \vs700_w81d_v202\vs700_w81d_v202\Files\64bit\ folder and install as you would normally.  When prompted plug in/turn on your 700 interface. (Note, if you've already installed the driver before, the install tool may prompt you to uninstall and reboot - if this happens, you'll have to turn-off driver signing and reboot again!) (I did try this and it does work to uninstall and reinstall...)
Once detected, you should get a warning about installing unsigned drivers.  Just accept the risk and let the driver install.
 
If all goes well, after a few minutes, drivers will install and the installer program will run to completion... 
 
I went and started my Sonar Platinum program and everything worked perfectly except for Addictive Drums which now didn't recognize my computer!  Reran the XLN Online Installer and added the computer to the profile and after some waiting had it running again in SONAR.
 
I now will install the NVIDIA graphics drivers and see about getting my monitors back and start using this puppy again... let you know if I run into anything else that's crazy...

I have the technical preview installed in an old DAW but never tried to connect my VS700 because, as far as I know, Roland codes it's drivers for only official Windows OS.  There's is a hack you can do but I've never bothered to try it.

I'm sure Roland will be updating the drivers. We likely won't see them for a week or so after the Windows 10 release. I'm more concerned with how Sonar will play in Win10. I'd assume fine since there won't be any major code changes to the OS.

I have V100 and am wondering how long I wil be able to use it.

I use the VS100 on this computer and the 700 on the studio computer. Not worried about it at all. They have been good about getting the updated drivers. Just don't freak out if they aren't there day 1.

Roland will update both the 700 and 100 drivers for Win10.

Resurrecting this question, now the hour is almost upon us. Anyone tried this yet?

I contacted Roland a few weeks ago and they were just waiting on the driver to be sent to them from Roland Japan. The request was already in for it. :)

Ah, marvellous.
 
What I am curious about though, is if anyone's already got it working. Noel mentioned in another thread that there were reasonably good odds it would just work if you did an upgrade to Windows 10 rather than a clean install, as the only real barrier to it working is the driver's installer, not the driver itself. Of course, I want somebody else to take that gamble first :)
