Package manager console crash in visual studio 2015 enterprise just after start with error:
Windows PowerShell updated your execution policy successfu
I had the same issue and found solution that worked for me: set execution policy to "Undefined" in all scopes (Remove registry key for Machine and User scopes if they are set by domain policy) and then restart VS and open Package Manager Console.
Edit: path to key I deleted:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\PowerShell
Key: ExecutionPolicy
This command line can be used to automate the process (run as admin), until issue is fixed:
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\PowerShell /v ExecutionPolicy /f
