Under Tools – Options – Environment – Startup, you’ll find the At startup: combo box.  You can select to open to

• whatever your web browser home page is set to.  (Note: this option is found in Tools – Options – Environment – Web Browser)
• the last loaded solution
• to show the open project dialog
• to show the new project dialog
• to open with nothing opened (show empty environment)
• or to show the start page (default)

When I was working on either my test cases or the automation framework, I would have the “last loaded solution” option set.  When I was doing ad-hoc testing (just randomly testing for bugs), I would have “Show empty environment” or “Show the new project dialog” set.
