Hi Steve,
You have the original backup image file that we created.
You can reload from that, follow the install procedure used to get the VS700 working... and then skip the anniversary update from Win10.
This is one obvious example of why you want to create and keep an up-to-date backup image file of your boot drive.
Things like this can happen over time... and it's a quick/easy way to remedy the situation.
I'm available if you need assistance.
