I have Windows 10 build 1511, where I have installed SQL Server 2014.
After installation everything is OK.
I\'ve made several times shutdown on Windows 10, a
pay Attention in suffix too
example: if in your user Secedit.msc is as contoso\usersql, in the windows service needs to be the same, I was putting usersql@contoso.com and was having problems to start the service automatic, after change to contoso\usersql, working fine
