    Mouse And Keyboard Not Working After April Updates.

    First, I appreciate what you are doing here. Second, my keyboard and mouse
    don't work when I start my computer. This is what I know:

    a. Everything worked and I have all my drivers up to date.
    b. I tried with both; a combo bluetooh set and an USB conected one.
    c. it keeps asking me for a driver for an "unknown device"
    d. if i boot the sysem in "safe mode". The bluetooh combo; mouse and
    keyboard work just fine (in fact that's how I'm typing right now), even
    thought it keeps asking me for the "unknown device" driver".
    e. I tried unistalling the update KB938371 after I unistalled the other ones
    in safe mode. The computer or windows doesn't let me do that. Because is
    the only one I cannot unistalled and the problems repeats itself I am almost
    sure that's the problem or very related to that.
    Please, help.

    I have the exact problem. After the recent Microsoft Updates, 3 stages, my
    mouse and keyboard are not recognized. I did system restore back to 4/6 and
    then back to 4/2 and the problem does not go away. I have a Dell desktop
    (less than 1 year old) with Vista Home Premium. I spent several hours on the
    phone with Dell support, and they couldn't figure it out either, and I am
    waiting for a call-back. The mouse/keyboard work when I boot from the DVD,
    but now I can't even use them in safe mode.

    Thanks for the article. I hope to be able to install SP1 in the future. DO
    you have any suggestions for my situation? With neither a mouse nor a
    keyboard operating, there appears to be no way to update the drivers or to
    "uninstall/reinstall" them.

    I am having the same exact problem - but it was post SP1. I had SP1
    installed via TechNet for about a week before this update (KB938371)
    came out - and things were working fine.. (Yes, I was allowed to
    install it - I don't know where this talk of KB938371 being a
    prerequisite for SP1 comes from, although I do read things about
    (another version?) of KB938371 being released sometime in feb?)

    Regardless, after the install, my mouse and keyboard are dead,
    internal touchpad and keyboard on my laptop show as "unknown device",
    whereas my external mouse shows as "USB HID Device" and is

    The external mouse dies after the update is installed, and the
    keyboard and internal touchpad die after the subsequent reboot when
    the drivers are hosed.

    I cannot change drivers to generic ones, and when I try to install
    drivers for what is available (sorry MS guys, I do not have a
    "keyboard driver", sheesh!) I get messages such as "access denied" or
    "the file cannot be found" or "this driver was designed for windows 95
    or later."

    This is a very bad one - especially since many people aren't even able
    to mention this online, since they can't get into their computers. I
    submitted a support request to MS, so we shall see. However, I sense
    a form letter with "please contact the manufacturer of your computer"
    in my future.

    Unfortunately it won't.. They told me simply to call in to support;
    their "current fix" was to reinstall and not install KB938371.

    MS are looking into the problem.

    Since you have KB938371 could you please forward the following files to Eric -


    You might have to boot from the DVD to get into the computer. It may work.

    Well, I do not have KB938371 installed anymore, since I had to restore
    from a backup in order to use my machine at all.. I have work to do
    this weekend, and that includes catching a flight early tomorrow
    morning, so I'm not about to kill my machine again right now in order
    to troubleshoot tonight, unless this is something that's already on my
    machine. Maybe I can try that again Sunday, but I can't promise it.

    Are you asking for the setupapi.log AFTER KB938371 was installed? Even
    if I were to reapply the patch, that would be difficult, as I can't
    even log in after that update is installed..

    Booting from the DVD gets me recovery options, but I don't have a
    floppy in my computer so I can't exactly copy off those files with
    recovery console or something. Any other ideas?

    I imagine I could reapply the patch, copy the files to another
    partition, then restore from backup again.. Honestly, I don't have the
    time to do that tonight. I'm on a tough work schedule and this thing
    has cost me enough time. I appreciate this TaurArian and Eric, but
    unfortuantely I just don't have the time to get those files now..
    (Sorry everyone else - can anyone else get the logs after installing
    the patch?)

    Are you saying that microsoft can't re-create this in-house, or the
    fix may not be universal, to the point where users have to send in
    individual setupapi.log files?

    I contacted Eric, to see if there was anything else I could do in the
    meantime or if he had any updates...

    An idea I did have.. I could RDP into my machine from another in order
    to grab those files... Unfortunately I won't be able to try that until

    I have the same problem. After installing the Update for Windows Vista
    KB938371, which is 2/3rds installed before the computer shuts down then boots
    and installs the last 3rd, my Logitech G5 Laser mouse won't work so I have to
    use the Microsoft key and go to System Restore to use my computer.

    Also, I have Bitdefender antivirus so I don't use Windows Defender. But
    Windows Update keeps askng me to imstall the latest Defender virus
    definitions though I've tried to install them several times. I think it may
    be related that when I boot my computer, I gat a menu that says "Application
    failed to initialize 0x800106ba" (?).

    For your Windows Defender problem:

    Error message when you run Windows Defender: "Error Code 0x800106ba"

    I was extremelly frustrated with the whole thing and the lack of solution
    from both DELL and Microsoft so I went ahead and "play around". If you have
    a DELL computer this is what I did. Its kind of extreme, but it worked for

    a. I backed up all my data; documents, etc. into a flashdrive. I used a USB
    mouse instead (make sure is want you don't need a driver for -- I know
    finding one is a pain in the neck). The good part is that you can do the
    rest of this without a keyboard.

    b. When you are booting your computer press F8 and follow instruction to get
    the system to be restored to the way it was when left the factory. If your
    computer has a manual it will guide you step by step. I have an DELL XPS 420
    and I have been told most computers from DELL have this 2006. Please, check
    with your manufacter.

    c. It took a little bit but it does restore the computer to how it when I
    received the system.

    d. I set it up so it wouldn't update critical updates.

    e. I downloaded all the new drivers (If I didn't have the latest) from DELL.
    Focus specially in the ones related to your keyboard/mouse and memory cards
    (and bluetooh hardware if you have it). I first checked with the "Device
    Manager feature" to see what I really got in my computer. Also, you should
    have a blue CD with the original drivers so you can compare. What you have
    in that CD with a check mark should be the same you have at that moment in
    the computer. Also, one of the files was a firmware (in my case) for the
    bluetooth/19-1 card reader. Notice: if you have an antivirus I highly
    recommend to stop it before installing the drivers.

    f. I did a clean disk and I defragmented the disk(s).

    i. I turned on the antivirus.

    h. I turned on the Windows Updates with both Critical and optional updates
    and with the option to install them automatically, but install them when I

    i. I re-booted my system.

    j. I let all the updates I choose to install (41 of them!), including the
    April ones.

    K. Once it told me that there were ready to be installed I turned off my
    antivirus and I installed them.

    L. Once it rebooted everything worked.

    Now, I have to say that I still don't understand what trigger the issue or
    if it will be a mess when I install SP1 when it is available through the
    Windows Update, but so far I have had not problems. I still believe is a
    Windows Vista issue, not DELLS because I notice I have changes made into my
    registry at levels I didn't expect it. I don't have any extra-software
    except the Pen-icillin as antivirus. Anyway, if this helps anybody it will
    be great. I was so frustrated I couldn't wait any longer. Good luck to

    I am a developer at Microsoft looking into this problem. We have been
    trying to reproduce this issue but no luck for days. However, from examining
    logs, we believe this is happenning because your system lost MSMOUSE.INF
    and/or KEYBOARD.INF from \windows\inf folder.

    Can any of you check your system and see if you indeed do not see these INF
    files in your \Windows\INF folder?

    To fix this issue, you can copy MSMOUSE.INF and/or KEYBOARD.INF from


    to \Windows\INF folder and let PnP takes care of driver install (you may
    need to do "update driver").

    Please let me know if this is what you see?

    I also lost mouse control after installing KB938371., however my keyboard remained active. I have a Microsoft wireless keyboard and mouse.

    I fiddled around for some time trying to find the mouse driver etc but the mouse file had completely disappeared from system management.

    In the end I perfomed a System Restore back to a time before the update was installed. That brought the mouse back to the system. I will now refrain from again installing KB938371.

    My system is a Dell Dimension 5150 running Vista Home Premium.

    Since my last reply I experimentally installed KB938371 again and this time it did not interfere with the mouse or keyboard. I wonder why?

    My system is fully functional.

    My mouse and keyboard were missing from the windows inf so I did as you said
    and copied them into the INF folder. I then updated the drivers. Problem is
    the mouse froze. I had to do a system restore in safe mode to get it back. I
    still can't get this update KB938371 my mouse completely disappears when I try
    to install it. My keyboard is ok though.

    I was looking at the installed updates on my computer and I see that update
    KB938371 was installed on Feb 13 2008. Do I even need the April update of
    KB938371 or is this a patch for the Feb update?

    I'm having this same problem with my touchpad and mouse. I can not get into
    my computer to check my system to see if these files are missing. What
    should I do?

    I can't even get into my laptop. I'm communicating to you through my work
    computer. My keyboard, touchpad and mouse are all not working. When I
    bootup it takes me straight to the restore screen. The arrow keys are not
    working because the keyboard is not working. I'm so frustrated because it
    hasn't been working for a month now. Can you please tell what I can do .

    Yes, April release has some additional updates over Feb release so you will
    need it. However, if you copy msmouse.inf and keyboard.inf to \windows\inf
    folder, you should not lose mouse/keyboard.

    If you copy msmouse.inf from
    to \windows\inf folder, you should be Ok after installing KB938371. Your
    system may have some additional mouse driver (like Logitech driver) that you
    may need to re-install.

    It still didn't work. My mouse still disapears after i restart after I
    download the update.

    Try this out...

    IF YOU HAVE A SYSTEM RESTORE POINT USE IT, and then turn off automatic updates.

    After a specific update which is PRE Service Pack 1. It will cause you to lose your mouse and or keyboard. This issue is more exclusive to wireless devices, and alot harder to fix "in" wireless devices. Now I know someones thinking, "but this happened AFTER SP1". Well I say to you the update that cause it is a pre-req for SP1 and is included in the Stand Alone version. Thus if you downloaded SP1 you wouldn't have had the issue untill.... get this... after the install of SP1.

    The following outlines a solution. However, it isn't 100% for all your devices. I've seen it work on all wired USB mice, but some wireless devices remail unfixed.

    First be ready for alot of trial and error, because we're going to attempt to restore the inf which your mouse is looking for. Thus we will be using a backup file. Now if you're the person who has used a billion mice on his machine... well this is going to suck for you. But, on the contrast if you're the person who's only ever used one mouse it's your lucky day.

    1) Navigate to C:\WINDOWS\INF
    3) If you don't have them don't worry, if you do copy them to your desktop for safe keeping.

    Next we need to locate a backup for this file. There are a few locations you can try see from the list below:


    You can do an advanced search in these locations for the peciously mentioned files (or) you can search via the command prompt. If you're using the command prompt navigate to the specific directory and type:


    You will need to find one of each that have matching dates. Your best bet would be the FILEREPOSITORY, but as mentioned before it's trial and error. Also, please select a file date that is BEFORE you started having the issue. I know everyone "should" have common sense, but you can't count on it.

    Once you've found the files you want to use copy them to your C:\WINDOWS\INF directory. Then lets navigate to the Device Manager... if you don't know where its at type "device manager" in the Start Search Bar.

    Once there we need to locate any "ghosted" entries and uninstall them. To do this you need to goto VIEW > SHOW HIDDEN DEVICES. If you have any transparent listings for mice or HID uninstall them and move on.

    Now reconnect your failed device, and see if the system recognizes it. If it does it should install the driver etc... and hopefully you're good to go. If not it's back to finding a INF that will work for you. It will take several attempts, but you'll get it.

    Also, if the device driver installs correctly and still doesn't work. Check the device manager and ensure the device is enabled. I've seen this happen so you simply have to check that it is... in essence.. turned on. Another note if you have a way to remote into your machine it makes this whole process alot faster, because you have a mouse! Anyways hopefully this helps. Also, should you contact MS support please do not refernce this post.

    * One more thing. * Should you have NO mouse or keyboard this all can be done from the WINRE. It is a pain, but it is possible. Simply boot off your disc and once in the setup enviornment press Shift+F10 for a command prompt. You can go through all these steps in the command prompt to restore your two devices. If your keyboard is failed you will need to look for one additonal file which is MSKEYBOARD.INF.

    Glad to hear Microsoft is looking into the problem. <micrsoft rant/>

    Look this issue has cropped up on my HP nc8430 laptop this week April 10. I
    have no keyboard or touchpad functionality. I'm unable to go back to a
    previous restore point, as the rollbacked failed with an error. The only
    reason I can login to my laptop is via the fingerprint scanner.

    I've tried all the windows/inf suggestions without any luck.

    This is one of the most troubling issues I've come across in some time. I
    really think it is the end of the road for me and Windows, I can't handle the
    pain anymore. Honestly DOS 5.0 would be better than this mess.

    Can microsoft please provide an update on this issue, it have been over a
    month since an offical response on this topic.

    I have an Acer TM5515 laptop with Windows Vista Home Premium SP1 and since a few months I have problems with my touchpad. The cursor is behaving irrational and I can not use the advanced features of the touchpad anymore (I get the announcement: “can’t connect to the driver of the Synaptics pointing device”).
    I tried a bios update and I tried uninstalling and reinstalling the newest drivers, but nothing solved the problem. I cannot reinstall the driver. After trying to install the synapticsdriver I get the announcement that the installation of the Synaptics (HidUsb) HDClass was successful, but the installation of Synaptics (SynTP) Mouse was not successful.
    This week I had to install a new Acer Travelmate laptop (5320) and by installing the Windows Updates one-by-one I finally found out the problem is KB938371. After installing this update on the new laptop, the same problem occurred. Back to the restore point from before installing this update, and the touchpad worked fine again. So on this laptop I did not install KB938371.
    Although I did not miss msmouse.inf and keyboard.inf, I tried on the other laptop (on which KB938371 was installed months ago) Dasukes solution combined with uninstalling and reinstalling the synaptics drivers, but that didn’t help.

    Has anybody an idea about what I can try to solve this probem? Is Microsoft working on a solution? Is there a way to delete KB938371, without having to go back to an image from months ago?

    Here's what Worked for me. I rebooted and held down F8 to access the
    safe mode options. I choose the option Disable Driver Signature
    Enforcement. This worked for me so I started checking my mouse and
    keyboard drivers, they were all signed, I found however that my USB
    ports drivers were not signed, they were some how updated to Windows
    Vista SP2 Beta drivers that are not signed.

    For now I'll run with out driver signature enforcement, unsure if this
    was enabled before or if it was enabled by a patch

    MICROSOFT KEYBOARD ~ Quick Fix Guest


    My husband and I have been experiencing problems with our keyboards
    freezing up within a few days of each other. Both Keyboards are the same
    "Microsoft Wireless Multi Media 1.0A" , they came together with our CTL
    Computers. For about a week we checked the status of the Keyboard which said
    it had a strong connection with the computer, we changed all of the
    batteries, went onto the internet to get advice but nothing helped.
    This morning, I took the Wireless Keyboard and put it next to the
    Transmitter or Reciever and pushed the reset button as I pushed the reset
    button on the bottom of the Keyboard and a quick note came up and said that
    the "F lock" was unlocked, I have no idea what it meant but the Keyboard
    works now. I did the same thing to our other "Wireless Keyboard" and it now
    works also!
    On the bottom of the "Transmitter/Receiver there is a picture of the reset
    buttons being pushed at the same time for the Keyboard & Mouse. Maybe somehow
    they lost their signals.
