Thank you.
The process did eventually finish (ca. 6hrs), and initially the results looked good -- start-up was quick. However, some WMI configuration or objects needed for Hyper-V have disappeared; so my two VMs, which are at the core of my consulting business, are inaccessible. I restored the registry, as you recommended, without any problems, but also without any improvement.
I have been trying to restore from a restore point all morning. The one I requested to be made during the Windows Repair process is nowhere to be found, and Windows has had trouble with the two previous restore points I have selected. It's working on the third one now.
Do you have any recommendations for me on the Hyper V problems? I have been down nearly 24 hours.
Thank you
