It looks like you wanted a Windows collation during installation, but selected a SQL collation instead. I can not find any windows collations that look like this: latin1_general_CP1_CI_AS. The CP (Code Page) leads me to believe this is a SQL collation. The windows collations don't have a code page.
You have two choices at this point, changing the default server collation (which involves a lot of work) or just remember to specify the collation you want on user databases you create. Be sure to read BOL if you are considering reinstalling SQL and already have user databases set up.
