    Difference between clean install and upgrade (files only)?

    Just a curiosity of mine - Is there a difference between a clean install and performing an upgrade while keeping only the files? In other words, is this sort of upgrade the same as a clean install, only with the files restored to 'documents', desktop, etc.? Or, does the new windows folder contain remnants of the previous install.

    Unless I am totally wrong, an upgrade keeps a copy of previous settings so you can revert back to previous version if you wish (windows.old keeps previous settings)

    clean install wipes everything except what you ask it to keep
