Do version upgrades use $unisntal folders?

    There are a couple of freeware/shareware apps that make deleting the
    $uninstall folders easier. They make a good argument that it is extremely
    rare to need to uninstall a patch after Windows has been running for a few
    days. And they take up GB of space!! But I wondered if, say, when you
    install a new version of Office or Windows Explorer, does the process do an
    uninstall of the previous version, needing access to those folders?

    Windows Explorer is built in to XP and any update(s) to it will store
    the uninstall information in a $NtUninstallKBxxxxxx$ subfolder. It's
    technically not an upgrade, it's been updated.

    If you meant an upgrade to Internet Explorer 7/8, it's uninstall files
    are in a subfolder of Windows named ie7/8 and it's updates uninstall
    subfolders are in ie7/8updates. Technically speaking, the "process" does
    not uninstall the previous version as it will leave it's files in place
    but, the path to IE will point to the newest version and the older
    version will not be able to run.

    AFAIK, Office does not uninstall older versions of it.
