After recent update, mouse is acting funny

My desktop gamer updated Windows 11 on the 11th of August, 2026. After this update, my mouse has been randomly click locking at times, and other times it will not respond to left or right clicks. When it locks, it is like I am holding the left mouse button down, but I am not. I can move the cursor around, but it highlights everything. It happens about two or three times in an hour of use. I have also noticed that my Bluetooth isn't working now.

It is a wireless mouse and connected through a USB 3.0 hub.

I tried reloading all my USB drivers and my mouse drivers. I also tried reloading my video card drivers. I ran a system diagnostics, and it found nothing. I did try removing the updates, but Windows will just update again right after.

I also tried running these two CMD lines: 1. dism /online /cleanup-image /restorehealth 2. sfc /scannow

I am at a loss.

    I am experiencing similar issues with my mouse. This has been happening since July, at minimum. I uninstalled the updated and the mouse worked normal, but as soon as the system automatically updated, the mouse started acting up again.

    Every 3-4 clicks, the mouse automatically double clicks (translating to closing additional windows, not selecting text, etc.) and it has been really frustrating. The device mousepad works, but it is not as easy to use.

    I have completed everything in the AI instructions and this still remains and issue.

    Hi John Johnson,

    I understand how disruptive this can be, especially since both the mouse behavior and Bluetooth changed after the update.

    At this point, I recommend that you review and try the steps provided in the AI generated answer on your thread. That reply typically include the most relevant checks for this scenario. 

    Could you check whether Turn on ClickLock is enabled under Settings > Bluetooth & devices > Mouse > Additional mouse settings > Buttons? If enabled, turn it off and test again, as ClickLock can make Windows behave as though the left mouse button is being held down.

    Please also check Device Manager and let me know whether the Bluetooth category is still present or if any device has a warning icon. Since Bluetooth is affected as well, try installing the latest chipset and Bluetooth drivers directly from your PC or motherboard manufacturer’s support page.

    Additionally, could you share the KB number of the update installed on August 11? You can find it under Settings > Windows Update > Update history. Testing in Safe Mode would also help determine whether a background application is interfering with mouse input. Thank you so much for your understanding.

    Since reinstalling USB, mouse, video drivers, and running DISM and SFC did not help, focus on the hardware path and Windows Update path first:

    1. Disconnect and reconnect the mouse.
      • Unplug the USB cable or receiver, wait briefly, then plug it back in.
      • Try a different USB port on the PC.
      • If the mouse is connected through a USB hub, remove the hub and connect the mouse directly to the PC.
    2. Check the mouse itself.
      • Inspect the cable or receiver for damage.
      • If the mouse is battery-powered, replace or fully charge the batteries.
      • Make sure dirt is not blocking buttons or sensors.
      • Test the mouse on another PC. If the same click-locking or missing clicks happen there, the mouse likely needs replacement.
    3. If the mouse is wireless or Bluetooth-based, reset the wireless connection.
      • If there is a Reset button on the mouse or USB receiver, use it.
      • For a USB wireless receiver, unplug it for about 10 seconds and plug it back in.
      • For Bluetooth-related issues, also use the Bluetooth troubleshooting guidance in Windows.
    4. Check for Windows updates again.
      • In the taskbar search box, type check for updates.
      • Select Check for updates.
      • Under Windows Update, select Check for updates and install anything available.
      • Windows Update can also provide driver updates, although there might not be any available.
    5. Reinstall or update the mouse device driver from Device Manager.
      • In the taskbar search box, type device manager.
      • Select Device Manager.
      • Find the mouse device in the hardware list and double-click it.
      • Open the Driver tab.
      • Select Update Driver and follow the prompts.

    Because Bluetooth also stopped working after the update, this points more to an input or wireless-device path than to the video driver. If the mouse works normally on another PC, the next best step is Windows Update plus driver refresh through Device Manager. If the mouse fails on another PC too, replace the mouse or its receiver.
