The service pack apparently set your screen resolution to the highest setting. You just need to reset your computer's video card display properties. I don't recall exactly how it's done with Vista, but with all previous versions of Windows, you can simply right-click on the desktop, and from the pop-up menu, select "Properties". In the next "window" that pops up, click on the "Settings" tab, and there you should see a way to adjust the "Screen resolution". Usually, you just have to drag a pointer to the setting you want, and click the "OK" button. You may have to play with it, (go through it more than once, that is), to get the setting you want. You can do all sorts of other adjustments in that window, and on the other tabs, if you are inclined to do so.
If that doesn't work with Vista, left-click on the start button, and select "Control Panel". From there select "Appearance and Themes", (or whatever the Vista version of that description might be), and in the next window, you should see a menu option that says something like "Change the screen resolution". If you click on that, you should get the same window for making adjustments that you would get by using the first method I described.
If you need help, more details, or whatever, just let me know.
