Mouse errors render windows unusable

Every time I open a window and then try to use an alternate window on a separate monitor I cannot access anything via the pointer until I ctrl+alt+del and allow the mouse to reset, only to have to do it again a few seconds later. I have tried multiple mice, deleting the app data info as directed (which automatically replaces itself) restarted so many times, and I have had keys get stuck like scroll lock and my n and g keys which I can only assume is again due to my editing the keys on my mouse and then trying to have it work as intended.

    Try this in order:

    1. Check the hardware path first
      • Unplug the mouse and plug it back in after a short wait.
      • Try a different USB port.
      • If the mouse is connected through a USB hub, remove the hub and connect the mouse directly to the PC.
      • If the mouse is wireless, replace or recharge the batteries.
      • Make sure there is no dirt blocking the mouse sensor or keyboard keys.
    2. Rule out a device fault
      • Test the mouse on another PC.
      • Since multiple mice were already tried, also check whether the same problem happens with each one on this PC. If they work normally on another PC, the issue is likely with Windows, drivers, or the current PC rather than the mouse itself.
    3. Update Windows and drivers
      • Go to Start > Settings > Update & Security > Windows Update and install available updates.
      • To update the device driver manually:
        1. Type device manager in the taskbar search box and open Device Manager.
        2. Find the mouse device.
        3. Open its Driver tab.
        4. Select Update Driver and follow the prompts.
      • If recent updates were installed, restart the PC to refresh drivers.
    4. Reduce pointer/input instability
      • Close all open apps and test again. If performance improves, open apps may be interfering with the connection.
      • Go to Start > Settings > Devices > Mouse > Additional mouse options > Pointer Options and adjust pointer speed.
      • Go to Start > Settings > Devices > Mouse and review mouse settings if button or scrolling behavior is not acting as expected.
    5. If the device is Bluetooth
      • Remove the mouse from Start > Settings > Devices > Bluetooth & other devices and pair it again.
      • Turn off other Bluetooth devices temporarily to check for interference.
      • If the pairing light flashes three times and turns off, the mouse may already be paired to another PC nearby. Remove it from that PC, then pair it again on the intended PC.
    6. For the stuck key behavior
      • If what is typed does not match what appears on screen, verify the keyboard input language matches the PC language in Start > Settings > Time & language > Region & language.
      • If special keys are not functioning correctly, install the latest Windows updates.
    7. If the problem continues
      • Connect the mouse or keyboard to another PC. If the device does not work there either, replacement may be necessary.
      • If the devices work on another PC but fail on this one, the issue is more likely related to Windows, drivers, or the PC’s connection path.

    Avoid registry changes unless the issue specifically matches an older Windows 7 or Vista sleep-resume problem. Registry edits are risky and incorrect changes can cause serious system problems.

    Welcome tac 216,

    Thanks for reaching out to Microsoft Q&A Forum. I understand that when you move between windows on separate monitors, the mouse pointer stops allowing you to interact with them until you press Ctrl+Alt+Delete, and you are also experiencing occasional stuck-key behavior.

    Does the issue still occur if you temporarily disconnect the second monitor and use only one display? Also, are the monitors connected directly to the PC, or through a dock/adapter?

    Please make sure you already tried the Q&A Assist steps. In addition, please try the following:

    1, Reset the graphics driver when the issue occurs

    • Press Windows key + Ctrl + Shift + B
    • The screen may briefly flicker while the graphics driver resets
    • Check whether mouse interaction returns without using Ctrl+Alt+Delete

    2, Perform a clean boot

    • Search for msconfig and open System Configuration
    • On the Services tab, select Hide all Microsoft services, then select Disable all and Apply
    • Open the Startup tab > Open Task Manager and disable enabled startup items
    • Restart the computer and test the mouse and keyboard again
    • If the issue disappears, this helps isolate a background application or service causing the conflict

    3, Repair Windows system files

    • Open Command Prompt as administrator
    • Run DISM.exe /Online /Cleanup-image /Restorehealth and allow it to complete
    • Then run sfc /scannow
    • Restart Windows after the scan completes

    Looking forward to your update.
