I have just reinstalled XP Pro. Since reinstallation Windows Explorer will only open in Folders view and in My Documents. I have tried a few of the suggestions here, however nothing will change how Windows Explorer opens.
This is how to make my computer open with folder view. Maybe you could try reversing it somehow for what you want. Don't forget to do a system restore just in case it is not what you want & you can't get back.
How to Make My Computer Open in Explore Mode With Folder List
In My Computer click Tools menu, and then click Options.
Click the File Types tab. In the list of file types, highlight "(NONE) Folders"
Click Advanced button, In the Actions box, highlight "Explore" Click "Set Default"
