Can't Enable Hyper-V on Windows 10 Enterprise

Question

I have a machine running Windows 10 Enterprise.  It used to have Hyper-V enabled, but I disabled it to run VirtualBox.  I've now removed virtualbox.  Every attempt I've made to enable Hyper-V results in error 0x80073701 (assembly not found).  I've tried every suggestion I could find to get it working with no luck.  Here is my systeminfo:

Hyper-V Requirements:      A hypervisor has been detected. Features required for Hyper-V will not be displayed.

I've been able to successfully install the Hyper-V manager, but not the platform. 

I've tried everything I could here.

I tried running the wu10.diagcab tool with no luck.

The system seems to think that virtualization software is already running, but it isn't.  Is this contained in a registry key somewhere?
