Removing items using the registry

To be much more efficient, you can run regedit and remove the items stored in:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\ProjectMRUList

Bear in mind that if you only want to remove a subset of items, you'll have to reorganize the list to maintain the proper sequence (no numbers skipped).
