1. Both VDI and console are black screen.

2. Windows Explorer is not running.
Try to find whether the windows explore is running with following steps
2.1  Call Ctrl+Alt+Del from the tool bar
2.2  Then click the "Task Manager"
2.3  From the Users tab, check whether the process Windows Explorer is running.

3. Try to manually start the Windows Explorer with following steps, but return missing MSVCP120.dll or MSVCR120.dll
3.1  Task Manager -> File -> Run new task
3.2  Enter cmd
3.3  Run the following command in the cmd

C:\Windows\explorer.exe

 

Need to check whether security software quarantined these 2 files.

To recover the Virtual Machine , the workaround is to recover the missing dlls:
1. Use the Process Monitoring tool to find out the path where the windows explorer try to find the MSVCP120.dll

2. Find a normal VDA(same type) and try to find out the path of the MSVCP120.dll.  For example "C:\Windows\System32"

3. Copy MSVCP120.dll and MSVCR120.dll in C:\Windows\System32 from the normal VDA to the issue VDA(if unable copy to C:\windows\System32, try to copy to C:\Users\userid\AppData\Local\Microsoft\WindowsApps)
