After upgrading to Windows 10, the Windows Phone 8 and 8 Update 1 emulators are not working, they are stuck at the message.
I tried deleting the VMs but still getting the same message. I also tried to repair the emulator installations but still the same problem. Please help.
---update----
I also uninstalled the Emulators, allowed the XDE.exe process through the Firewall and Windows defender, deleted the VMs in Hyper-V, but now am getting the following error messages:
I click OK and after a while this error comes and the Emulator shuts down.



That is difficult to say without the access to the computer, but i encountered the same error when updated from the Windows 8 to Windows 10 with the installed emulator. What i did to solve was to completely wipe out the emulator leftovers. I suspect that the migration was not very smoothless, and emulator was not able to detect the old virtual machines properly.
I would suggest you to do the same. Try to uninstall everything emulator-related and then go to
(or something like that, check both Program Files) and move VMs files to the different place. Then, install the development tools again - should work.
