    The most common problem for the “This PC” delays is networking. A network drive that was once connected is not present.

    If you boot your PC with the network cable disconnected, then the “This PC” will open instantly if you have this issue.

    This is because when you start your PC with networking enabled the “This
    PC” shortcut execution shows you a dialog with all of your drives and
    other system elements. It also invokes a parsing agent that looks for
    all those previous network locations to “fire them up” and “prepare
    them” for your viewing pleasure.

    You most likely have this delay caused from orphaned network locations
    if when you start your “This PC” it first shows a few icons then after a
    few seconds, waits and then shows a status bar. At the same time the
    status bar starts, the “Items count” appears. This is the local “This
    PC” telling you how many items there are and that it is done opening the
    “This PC” window. This is where the bug comes in. Now it is going to
    have a status bar while it tries to connect up to all those previous
    network locations. The rest of the time it is networking and parsing to
    find those previous network locations.

    I have not found a way to turn this parsing off yet. I am still
    looking. My PC did not do this until I used it for 3 weeks and
    discovered some network locations. Turning on and off sharing and
    network discovery does not seem to change “This PC” network parsing and
    discovery issues.
