For what it's worth, just about any Win 8.1 device driver will work with 10, and on a couple of new machines recently, I've just installed Win7 drivers that worked OK. But it's worth repeating, MS needs to back off on the sales pitch. BTW, currently, you can do a clean installation and activation with a Win7 or 8.x product id., so you no longer have to update, then activate, then perform a clean install.
