Issue fixed in this update

Windows 10 Version 1607 in-place upgrade freezes in the middle of the in-place upgrade while the Upgrade Operating System task is running. Usually a good indication that you are running into the problem is that Windows Setup freezes during driver inventory.

For example:

Date Time   CONX
Windows::Compat::Appraiser::WicaDeviceInventory::GetInventory (324):   Starting Device Inventory.

Date Time  CONX
Windows::Compat::Appraiser::DriverInventory::GetInventory (204):   Starting Driver Inventory.
