• Win 10 laptop - "wild mouse pointer" syndrome

    From NY@3:633/10 to All on Fri Aug 28 16:39:40 2026
    My Windows 10 laptop has just started exhibiting "wild mouse pointer"
    syndrome - the mouse pointer occasionally jumps horizontally or
    vertically on the screen by an inch or so (rarely in both directions at
    the same time), even when the mouse is kept perfectly still.
    Occasionally I've seen windows change position, as if I'd clicked on a window's title bar to bring it to the foreground. It happens at
    irregular intervals ranging from once every few seconds to once every
    five minutes. Each shift is a permanent one: it's not that the pointer
    moves somewhere else and then returns to its original position.

    It's a USB mouse, and I've tried two different mice of the same type, in
    all three USB ports. It happens both when the laptop is running on
    battery and on mains power.

    It is reliably cured by rebooting the PC, and then it's fine for a few
    hours.

    I can't see any common factor which provokes it: I just do standard
    things like reading or replying to emails in Thunderbird, browsing the
    web in Firefox, running LibreOffice Writer. I'm not aware of having
    installed any software that has started it happening. The laptop is
    about 5 years old and the problem has only just started.

    Somewhere in the mouse settings, on most operating systems, there is a setting to disable
    the touch pad. Some software even goes a bit further and has a check box to disable the
    touch pad when an external mouse is plugged. The latter is the best option since all you
    have to do to activate the touch pad is pull the mouse out.

    I jump around a lot of Linux systems testing them. Or used to. And it took a while to
    get used to booting up a new system and FIRST going to mouse settings and killing the
    touch pad in some way. I lay my hand/fingers on the touch pad a lot.

    Sadly its not that. I turned my touchpad off long ago because I was
    finding that I was getting spurious touches. Not sure how I turned it
    off, because there's nothing obvious in the OS to turn it back on, and
    there's Fn-F11 which toggles it but neither setting makes the touchpad
    move the pointer or respond to its left/right clock buttons. I remember
    even before I disabled the whole touchpad, I turned off "Tapping"
    because if I moved my finger several times across the pad to get the
    pointer from one side of the screen to the other, I often got a spurious left-click.

    I also found reference to the "Enhance pointer position" option in the
    Mouse applet of Control Panel and turned it off. I really thought that
    would work.

    It's very odd. It's only just started happening. And it's very
    irregular: it happens a few times in rapid succession and then behaves
    fine for tens of minutes.

    I suspect this is like my "left control key stops working" (on both
    external and internal keyboards, and sometimes other things happen) -
    just One Of Those Things; you've tried a different mouse and port, so
    doesn't _sound_ like it's hardware. I can't _think_ why a virus should
    do it, but maybe; as for failing memory, Paul is the expert there.

    (Mouse driver? But that wouldn't explain, any more than it would for me,
    why it has suddenly happened.)

    You say rebooting the PC sorts it, for a while at least; especially if
    you're the only user, "Switch User" might work - it does for my problem;
    second option down if you do Ctrl-Alt-Delete, and most things actually
    come back exactly as they were, which is better than a reboot. (I
    usually close Thunderbird, as that sometimes comes back as a tiny
    window.) Strangely, the misbehaving Ctrl key _does_ still work when used
    as part of that "three-fingered salute".

    Does the same thing happen in Linux? To find out, boot your computer
    from a live Linux USB flash drive and check that the mouse works properly.

    Generally, things like kits, you no longer have to download the whole thing, but you do have to figure out which single tick box to tick, to get
    the utilities installed. Right now, I don't have a devcon, and I do have
    at least one kit (partially) installed (Win10, the other disk on this machine).

    "Where to download DevCon

    DevCon (Devcon.exe) is included when you install the WDK, Visual Studio,
    and the Windows SDK for desktop apps. For information about downloading the kits, see

    The %WdkDir% represents the directory where you installed the WDK and X.Y refers

    Microsoft has, on occasion, released filter drivers where the INF
    caused the driver to "bind to all HID devices". An affected individual
    could have started with one OS, got some filter driver installed, and
    it only became an issue when upgrading to some other OS. This could be
    a filter driver intended for a touchpad, that binds to the mouse as
    well. The driver could then be attempting to interpret "virtual buttons"
    on the (non-existent) touchpad, based on X-Y coordinates.

    Generally, optical mice, the array sensor on the bottom is very
    good regarding dirt and obscuration. When you flip the mouse over
    and have a look, generally there is nothing to note in that area,
    no "fuzz" collects there. Whereas the "fuzz" does collect internally
    and can cause scroll wheel issues or mouse button issues. I actually
    swapped scroll wheel assemblies between two mice, in an effort to keep
    one of the mice "going". The bearing seemed to be going in one of them.
    Could not visually make out the defect.

    Some devices always have Filter drivers. A trackpad has a physical layer driver, plus it has a Filter driver to implement "virtual buttons"
    or "gestures". And these are sensitive to the current cursor X-Y coordinates. The filter driver then, watches the "stream" and "reacts" to certain things
    it sees in the stream. Mice don't generally have features like that,
    having physical buttons and plain X-Y coordinates.

    And yes, a check on Linux is a good verification step.

    In the history of computing, there have not been a lot of actual good
    hardware test programs. The Sparc computer, it could have a switch on it,
    to go into Test Mode, and their test program for their computer was excellent. They would test things that mattered. That comes with the computer.

    I have purchased programs for other ecosystems, only to be entirely dissatisfied with the "Hello World" style crap I was given. The only testing they did, was to make "stuff" appear on the screen, with no thought to
    what an actual hardware test should have. Like a snake-oil program that
    tells you it "detected 8000 problems" or "fixed 8000 problems", and it
    does the same thing, the next day. So so educational. I cannot recommend
    the average hardware test, as this is the level of material you get.

    In Linux, something like "Xev" can display what kind of event that clicking
    a mouse button might produce. Taking hands off keyboard and mouse, and
    just watching for your "glitch", Xev might even label what kind of event
    this was... that's if hardware reproduces issue on Linux, which it won't.
    This is a Windows problem.

    Yes. Existing installation of Win10 on a laptop that is several years
    old. Normal Windows updates as as when MS released them. AVG (free),
    CCleaner, MS Word, LibreOffice - all pretty standard stuff. Haven't
    installed any new software recently and I haven't AFAIK updated any drivers.

    As of a few days ago, the mouse (wired rather than wireless, Amazon
    Basics mouse) has started sometimes getting into a state where the
    pointer jumps about.

    Yes, I've two different mice of the same make/model, in all three USB
    sockets. And I've checked for fluff around the lens/sensor. If it had
    been random scroll wheel problems I'd have checked for internal fluff
    around the black/white segmented wheel and its sensor.

    Rebooting always fixes the problem and it takes an hour or so before the behaviour starts again.

    My impression is that it happens more often if I'm using the PC (eg
    moving the mouse, as you do in normal usage) and doesn't happen if the
    mouse is left idle.

    I tried with the mouse on its back so the laser is pointing upwards, so
    as to minimise the chance of stray reflections being interpreted as
    movement of the mouse. That makes no difference to how often the
    spurious movements occur.

    Occasionally I've seen windows change position, as if I'd clicked on a window's title bar to bring it to the foreground. It happens at
    irregular intervals ranging from once every few seconds to once every
    five minutes. Each shift is a permanent one: it's not that the pointer
    moves somewhere else and then returns to its original position.

    It's a USB mouse, and I've tried two different mice of the same type, in
    all three USB ports. It happens both when the laptop is running on
    battery and on mains power.

    It is reliably cured by rebooting the PC, and then it's fine for a few hours.

    I can't see any common factor which provokes it: I just do standard
    things like reading or replying to emails in Thunderbird, browsing the
    web in Firefox, running LibreOffice Writer. I'm not aware of having installed any software that has started it happening. The laptop is
    about 5 years old and the problem has only just started.

    Have you tried system restore to a pre-annoying mouse time?
    Have you tried safe mode?
    Have you tried disabling all non-essential startup programs?

    hand/fingers on the touch pad a lot.

    And, somehow, I've had a lot of touchpads that click themselves when I'm
    just moving over an icon.

    Next time it happens - and, sod's law, it's been behaving itself in the
    last two days - I'll try Switch User and see whether just restarting
    user processes (without restarting system processes) makes any difference.

    For my "left Ctrl Key" bug (other things happen too), just a Switch User
    clears it (them) - I don't need to restart anything (though I do close Thunderbird); everything comes back as it was, I think even the
    copy-paste buffer contents remain.

    Why not invest in a new computer, mouse and keyboard? You could also
    purchase dust covers to protect your valuable items! :).

    Ah, the ultimate helpdesk solution, after "reboot your system" and

    If that's your philosophy, what are you doing in a Windows 10 group? :-)

    Just running a Linux LiveDVD and watching the mouse pointer, might be
    enough to decide whether it is hardware related.
