The Control Panel subkey in the registry tutorial

The Control Panel subkey in the registry is where many of the Control Panel applets store settings and defaults. The number of sections may vary depending on installed components.Things that affect the number of sections include special mouse support, screen savers, and installed optional components. There may be some differences between a Windows Server and a Windows workstation installation. This subkey also includes data stored in the win.ini and system.ini files on Windows 3.x and earlier.

Appearance Holds settings for Windows XP's appearance and the schemes used for display configuration.
Cache Appears to control how Control Panel applets are cached—don't you just hate it when there is a component that is both undocumented and apparently unused? I checked every system I could,and the Cache subkey was empty on all systems—both XP Professional and Server.
