    100% CPU caused by WUDFHost.exe

    All of a sudden this past week (12/10/2007) my Thinkpad laptop is exhibiting
    intermittent 100% cpu usage every few seconds. Looking at Task Manager in
    the Processes tab I can see WUDFHost.exe pop up to the top of the CPU usage
    list every few seconds corresponding to the pinning of the cpu meter in the
    sidebar.

    My guess is this started after this weeks updates from Microsoft because I
    haven't loaded anything new on this machine.

    It appears that this behavior is slowing down my machine too.

    Can anyone explain this situaton or provide a fix?

    Do a Google search for "WUDFhost.exe" and there is a host of explainations,
    with which you should be able to solve your problem.

    I did a Google search as you suggested but all I found were a bunch of sites
    offering to run a free registry scan. I don't know about you but I won't run
    a program from a random website.

    If you think you know a solution please post it rather than suggest that I
    do a google search.

    Hi Ron

    The post I sent to you gave a source of information regarding your problem,
    and a possible remedy.
    Did you go into Task Manager and disable the action, to see if it was the
    actual cause of you problem.
    If you do not wish to use the actions mentioned to solve the problem thats
    fine by me.
    As you maybe aware all people offering advise in these discussion groups are
    user just like you & I, some have vast experience & knowledge, but none are
    employees of MS.
    On these discussion groups you will sometimes get direct directions on how
    to solve a problem and sometimes a referral to an website/discussion group
    which may assist to solve a problem better.
    I rarely post in discussion groups if I have a problem, a lot problems have
    happened before and a web search will in a lot of cases provide information
    or possible solution.
    The advise given in these discussion group should be considered as general
    advise in nature and not personal/individual professional advise.
    Professional advise cost us all money.

    Happy Computing

    I don't think it makes any sense to go to task manager and disable
    WUDFHost.exe as you suggested. WUDFHost.exe is "Windows User Mode Driver
    Foundation" which sounds like something essential to running Windows.
