The command window isn't as easy to find as on my Windows 7 desktop, but I finally found it.
Windows 10 Home
Version 1607
OS Build 14393.0
Mind you, this is after yesterday's massive update. And I haven't tried Word Mobile or Excel Mobile since the update, because I had already uninstalled them. My plan is to use my third "seat" of an Office 2010 Home & Student 3-pack and put Word 2010 and Excel 2010 on the tablet. I hope it works, but it's upsetting that I have to use up a bought-and-paid license for the entire suite to get functionality that was supposed to be included in the purchase of the device.
