If you've been around previous Windows versions you more than likely remember some of the hideous desktop patterns that were available. They're still here in XP waiting to be resurrected. Hey, they can't be any worse than the default XP scheme, can they? On second thought, maybe they can.
The desktop patterns from previous versions are stored in the registry under HKEY_CURRENT_USER\Control Panel\Patterns. The names and values are shown in the screen capture below:
[Start] [Run] [Regedit] Registry Key: HKEY_CURRENT_USER\Control Panel\Desktop Modify/Create the Value Data Type(s) and Value Name(s) as detailed below. Data Type: REG_SZ [String Value] // Value Name: Pattern Setting for Value Data: [Use the data value from the chart above or Key HKEY_CURRENT_USER\Control Panel\Patterns] Exit Registry and Reboot
