Hi Susan -
MS was probably referring to a Repair Install
which reinstalls the OS while keeping all programs, settings and files in place. It's a same-version Upgrade install done from the desktop and may require uninstalling SP1 if you can't find an installer for your version with SP1 included.
However be aware that reimporting settings is a corruption path and inferior to a clean reinstall.
Here are the steps to get a perfect clean reinstall of factory OEM Windows 7, based on hundreds done here. You may not be ready to do it now, but at least you'll know what's involved and be prepared: Reinstalling Windows 7
