Explorer spazzing out

    What causes this? Every couple of hours, the system becomes jittery and
    slow. Digging into the details, Explorer is using upwards of 40% CPU and
    short-lived DLLhost.exe processes labeled "COM surrogate" are repeatedly
    being spawned, one every ten seconds or so.

    The parent process of the DLLhost.exe processes is a svchost.exe hosting
    two services: DCOM Server Process Launcher and Plug and Pray. This
    svchost.exe shows mildly elevated CPU use.

    I've turned off indexing and most of the other annoying things that
    randomly grab CPU and slow the system down. Indeed I find filename only
    searches faster with the indexer off than with it on (and with the
    indexer on, I sometimes even get false negatives with filename searches).
    That includes disabling the relevant services.

    Any idea what could be causing this Explorer/DCOM/PnP/DLLhost spasm to
    recur every few hours? It lasts up to ten minutes and in particular makes
    gaming impossible until it's over.
