Weird Touchpad Bug Win 11

Question

Previously there was a bug in my mouse that was flickering. but I managed to fix it by disabling the printscreen button. I tracked it down with carnac . But another problem came suddenly when carnac detected the "Lbutton OEM Clear" button which went crazy, as if it was being pressed continuously.

This annoys me quite a bit, because the mouse has disappeared. When I checked on the keyboard test, it turned out that the touchpad right-click button. I immediately disabled it via registery, via device manager, unplugged the flexible cable, through the application. But still the disturbance appears. I think it's a hardware malfunction, but for now how do I stop this touchpad madness for temporary.

Hi Faiz. I'm Greg, 10 years awarded Windows MVP, here to help you.

There are a series of touchpad repairs starting with finding the latest or better driver which need to be gone through before hacking the registry. After a dozen years daily in forums helping tens of thousands of people, including millions who use my tutorials which popularized Clean Installs with consumers, I can tell you that most registry hacks will come back to bite you. Every day I deal with customers here who blame Microsoft for bugs and find out later that they've hacked the registry and made other modifications which also almost always have unintended consequences.

So let's go over touchpad with the fixes that have worked for thousands of others I've helped with touchpads in forums.

1. Update the Touchpad driver from the PC maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you also have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.
2. If that doesn't help then enter Device Manager reached by right clicking the Start button, go to Mice > Touchpad and then Driver tab. Choose Update Driver, then Automatic to see if it gets a better driver that resolves the problem. If not try Update Driver > Browse > Let Me Pick to try all previously installed drivers.

If the touchpad doesn't show up, from Device Manager Action tab choose Scan for Hardware changes.

3. If that doesn't work then try uninstalling driver, Restart PC using keyboard to Ctrl Alt Del, on blue screen tab to Power Icon in bottom right, press Enter, arrow down to Restart, press Enter to restart to reinstall the driver.
4. Run the hardware troubleshooter at Settings > Update & Security > Troubleshoot. > Additional Troubleshooters.

5. Go to Settings > Devices > Touchpad to go over the Settings. Then choose Additional Settings which opens the Mouse properties box. The Touchpad software installs a tab onto it - usually the last one - that should have more settings to check, including a checkbox to Disable Touchpad when USB pointing device is attached. This prevents palm drag from causing the cursor to jump

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
