    running windows 10 on a Dell Precision laptopWhen I have larger PDF docs open my keyboard appears to start typing random letters. After several times of this happening and rebooting to clear the issue, I've come to realize this only happens when I have a pdf documents open and only when it's a multipage document, If I close the PDF, my keyboard returns to typing normally. This issue happens to both my laptop and my Bluetooth keyboard at the same time, which makes me think it's a windows issue. Also what appears to be random letters isn't so random. It appears random when I

  2. Keyboard typing random letters

    I am running Windows 10 build 18945 and random applications (most of them) are getting typed in random letters. I have found many things saying check your input language but i only have one that is English (US).

    And the random letter a key will type is not always the same. I can hold down 'a' for instance and it'll type a series of numbers and letters. So it is not consistent

    Example, copy and pasted holding down 'a'

    One of the only applications that correctly recognizes the input is Firefox

    Pretty sure it isn't a hardware issue, because it is not in all applications.

    This is an integrated keyboard in the Lenovo ThinkPad T430s

    It also seems to be intermittent

    EDIT If i remember right, this started around disabling credential and device guard (I can't use any emulator/virtualization with them on because the virtualization is then exclsuively used by Hyper-V, and i needed to run Intel HAXM)

  3. Keyboard Typing Random Letters

    Help! I don't know what happened but my keyboard will type seemingly random letters/number every time you push any key (even same key multiple times). I have gone into the computer's keyboard settings and switched languages from and back to the original
    English settings and nothing has changed. The odd thing is that it works on some programs and not others.

    It works on:

    Chrome, File Explorer, Internet Passwords, Steam, Spotify, iTunes

    Doesn't work on:

    Microsoft Settings, Cortana, Microsoft Store, OneNote, Sticky Notes, Calendar, Audible, Mail

    The trend is that it doesn't work on most Microsoft Applications but it does on the other Apps

    Random letter gets stuck and continuously types in all applications

    At random times when I am typing in whatever application or document I am in it suddenly gets stuck and continuously very rapidly types the same letter. I can't stop it and even if I switch to something else it just carries on typing wherever it can (including
    in the Windows search box) The only way to stop it is to shut down and restart the PC. I thought it was a faulty keyboard and so bought a new keyboard but the same thing is happening with the brand new keyboard. It is not the same letter each time so is not
    a sticking key. I have run a full virus check and nothing showing. I am on a Lenovo desktop, using a logitech wireless keyboard, Windows 10. Can anyone help?
