sql server EXPRESS instance with windows authentication does not have any permissions to create a db

sql server EXPRESS instance with windows authentication does not have any permissions to create a db.

i have installed VS 2008. so i got SQLEXpress installed. and then separately i installed management studio 2008.

When i connect to the instance using windows login, it connected. but It does not have permissions to create any db or create any login.

I had the exact same problem. When I completely reinstalled SQL Server 2008 Express and Management Studio the problem was missing. Also when you install the SQL Server you can add password for 'sa' user.
