    Hello Larry,

    Thank you for taking the time to post a comment. This Fix it actually disables USB storage devices.

    Are you attempting to block access to your storage device or are you not able to get a storage device to work?

    Thanks,

    -brian

    This Microsoft Fix it does not change any permissions on the machine. It only changes the Start value data to 4 as described under the Let me fix it myself section of the Knowledge Base article.

    To set the USBSTOR service back to the default settings you can edit the registry and change the Start value to 3.

    1) Click Start, and then click Run.

    2) In the Open box, type regedit, and then click OK.

    3) Locate and then click the following registry key:

        HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesUsbStor

    4) In the details pane, double-click Start.

    5) In the Value data box, type 3, click Hexadecimal (if it is not already selected), and then click OK.

    6) Exit Registry Editor.

    I’m confused.  The knowledge base article, "How can I prevent users from connecting to a USB storage device?" located at http://support.microsoft.com/kb/823732 lists resolutions for both:

    If a USB storage device is not already installed on the computer

    -and-

    If a USB storage device is already installed on the computer

    This fix it tool is listed to rectify "if a USB storage device is already installed".

    What is not clear to me if the fix it tool resolves if a "device is *not* already installed" and prevents those as well.  The title of this tool "Disable USB storage devices" leads you to believe it does, but by what means?

    Does the tool change the permissions for Usbstor.pnf and Usbstor.inf as described for the "not already installed" solution?  I found that to not be the case on my system after running the tool.

    It would be very helpful if after accepting the license agreement for the tool to actually be given a description of what the tool is about to do and give the user the opportunity to continue or cancel.  As it is now, it just runs with no further warning or info.

    It would also be very helpful to be able to undo this action.  There are no information or means to reverse this action provided.  I was hoping this blog would include this information, but it does not.

    We have blocked the USB access to the limited user in domain using group policy & batch file . This policy is working fine with USB drives which are alreay used but whenever user not having USB access connect a new USB drive it detects the USB drive automativally & user get the access & after restarting the system the access get blocked.

    So How can be blocked detection of new USB drive for the USB disabled users in domain ?

  15. Vince says:

    To lock down USB ports for mass storage devices:

    •         Sign on as administrator

    •         Open Windows Explorer & show hidden files & extensions for know file types (tools, folder options, view tab)

    •         Open the properties for C:WindowsInfUsbstor.inf & C:WindowsInfUsbstor.pnf

    •         On the security tab, deny all options for all users, including SYSTEM & Administrators

    •         Hide hidden files & hide extensions for known file types again

    •         Run Regedit & change the value data box to 3 for the following:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesUsbStorStart

    Someone is installing a keylogger on my computer, can these instructions stop it from working?

    I also don’t want anyone to be able to use my dvd/cd recorders (or whatever they are called) to copy anything from my computer.

    What do i do?

    Thank you very much.

    Peggy

    The best-kept secret in the fight against viruses and keyloggers is a company called HonorPC! They feature one-key recovery that leaves your documents, music, pictures, videos, and favorites intact! It works even if you have a problem that won’t allow Windows to start. I have done online banking on my HonorPC for almost three years and have never installed antivirus. I bought my HonorPC for $1,000, which included a 22” LG monitor and laser mouse. I recently got a Windows 7 upgrade from HonorPC and I’m very happy with it. Their web site is http://honorpc.com and they have their phone number right on the home page. You should check them out before they are bought out by a big computer company and banished from the face of the earth!
