<Domain\User>could not be authenticated when changing Authentication Type to Windows Authentication in SL 2015 CU1

Running SL 2015 CU1 on Windows 10 (my PC for testing). When I try and change to Windows Auth I get the following error:

<Domain\User> could not be authenticated. Please enter a valid windows user name with privileges to the domain SQL Server is running.

The domain user I am trying to use is what I use to login to the PC. I can also using Windows Auth in SQL Management studio to connect to SQL Server (again using my windows Id). I do see my domain user under security|logins in SQL Server. Running SQL Server 2014 developer edition.
