Hi Dustriplin - no, you have to hack the inf after updating to win 10...
 
and no, not hacking the existing inf file in system32.
 
Download the latest 8.1 driver for your V700.   V 2.02 I believe.
 
Unzip the file and where you've extracted look in: \vs700_w81d_v202\vs700_w81d_v202\Files\64bit\Files\
 
In there you will find RDIF1089.inf.  This is the file you want to edit.
 
Once edited & saved, turn-off driver signing, as previously explained.  After you've booted up with driver signing off, make sure your interface is disconnected from the USB connection, or powered off.  Then run setup.exe from the VS700_w82d_v202 directory and install as you would normally.  When prompted plug in/turn on your 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!)
 
Once detected, you should get a warning about installing unsigned drivers.  Just accept the risk and let the driver install.
 
Hope this helps,
Mack

Thanks Mack...confirms what I tried last time ... once I did the procedure you outlined here, the installer got stuck after I plugged in the interface and turned it on... Some things to still try is making sure the USB bank that I use in the motherboard is clean except for the 700 (something that I remembered could trip up the install in the past), making sure that all the other audio interfaces (on board and such) are off as well as any other programs that might be running (antivirus and things), also might pull other USB devices out and install the 700 first,...

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 [Machine] section:

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...
 
Best
Dur
 
 
 

Awesome job, dustriplin!
 
Keep us posted on stability & performance.  I think MY VS-100 is actually performing better in 10, than 8.1.  I seem to be able to run the latency lower without any distortion creeping in....

Fantastic news... good work.

 
It does feel pretty snappy... I finally was able to force my first audio drop at the lowest latency setting (1ms - ASIO) .... a 35 track tune with every heavy WAVES Signature Series plug-ins on about half the tracks , Bus Compression ARC and Ozone mastering  and a spectrum analyzer on the master fader... and me moving a bunch of faders and plug-in dials ... and no Windows optimizations ..  so far so good for what I will need.... pretty pleased right now with my rig and Windows 10.
Again, thanks John T and Mack for working this forum for us.

Well, this has finally prompted me to accept the "reserve Windows 10" thingy, so I assume it'll take a day or so to arrive.
 
Incidentally, I've been meaning to ask: what modifications did Black Lion do to your V700?

John,
I actually purchased Dyonight's full VS700 rig.  He used to be on the 700 forums a lot.  Really great guy, and gave me tons of helpful information on getting everything set up.  Really shortened the learning curve.  I think his Cakewalk thread about the mod was titled "BLA and the VS700-R" From what he said BLA took 10 months to fix to mod it and all he discover that they fixed were the op-amps in the outputs I think.  The Black Lion mod on the MOTU 2408 mk3 (which I use with the ART and Behringer units for big live recording jobs and when I get tired of the sound of the dang 700r fan!) was extensive and really made that unit shine.  The Black Lion Micro Clock that I used to sync everything is very nice as well.

If you want to force the download of Win 10, you can do so from here, and not have to wait on the reservation:

Thanks. I'm kind of busy though, so I think I'll wait. Makes more sense for me to do it some time later next week. Also still being cautious and seeing if any horror stories emerge.
 
It does seem to be going pretty well, this roll out, though.
