Before doing anything as drastic as a complete re-installation,
have you tried to replace the missing files? Reboot into Safe Mode and
Click Start > Run, and type "SFC /scannow," (without the quotes), and
press <Enter>. Have your installation CD handy.
If that doesn't work, a repair installation (a.k.a. In-Place
Upgrade) should preserve your settings.
