Assuming you mean the Windows Advanced System Settings screen, then right click on My Computer and choose Properties. On the left side of the screen you will see a link for Advanced System Settings.
You can also call them directly my pressing the windows key and R (which will bring up the run box) and typing
control sysdm.cpl
Let me know how you get on or if you mean something else.
Good Luck & Enjoy Windows 7
