Solved Windows 10 update caused touchpad malfunction

June 5, 2017 at 19:52:36
Specs: Windows 10
Squiggly lines that look like fireworks, from touchpad malfunction on my laptop, I think? It prevented me from signing into my laptop.. F2 completely didn't work F12 finally got me into safe mode after trying for a couple of hours, by pressing ESC and F8. But even in diagnostics and the blue recover screen, it would randomly push items and start me back over. Once I got into safe mode it took another couple of hours to type my passcode because it would constantly press the item in the bottom right or turn ease of access keyboard on so that it would delete everything I wrote. I finally am able to use an USB mouse, I am in safe mode, but these squiggly line that looks like bugs flying at night with burst of fireworks is still on my screen. It's no longer pressing random buttons, but touchpad doesn't work. It started this morning after a Windows 10 update.

"F2 completely didn't work F12 finally got me into safe mode after trying for a couple of hours, by pressing ESC and F8. But even in diagnostics and the blue recover screen, it would randomly push items and start me back over."

If this is happening before Windows even starts, then it has nothing to do with Windows updates. It sounds like you have a defective touch pad. And if the touchpad, graphics, and webcam are all acting up, you may have a defective motherboard.

Your link is missing.
If you are in safe mode with networking download all of your drivers from the system manufacture's web site (latest) and install them. See if that helps.

There is no guaranty that the update is at fault but it is a real possibility and the timing seems to point that way. If the driver update does not fix this you can see if you have System Restore turned on (I remember someone saying that it is turned off by default in Windows 10). If it is on and there is a restore point before the update you can roll things back to that date. If this resolves the problem then it was the update and you should wait a week or more before trying the update so they can make corrections to it.

You also can run Malwarebytes to see if the issue is caused by malware rather than the update. This can be run in safe mode. If you do not have networking (no internet) then you can download it on another machine and transfer the installer file via flash drive and install it.

You have to be a little bit crazy to keep you from going insane.

Your touch sensor appears to be broken. If cleaning the screen doesn't fix the issue, it's most likely hardware related.

I will try again with the link. I am back to square one, I tried to undo the updates and restart but this cursor is still there. My cursor that I use with an external mouse and the crazy cursor. Funny thing, during diagnostics it says the mouse is not active but I can still see that other cursor.

The integrated webcam comes is popping up defective. With error code 2000-0245, makes me wonder if their is a bug on my webcam? I am being tapped and it malfunctioned. Everything else pass diagnostics...

Like I said, if you've verified the screen is clean, the touch screen's digitizer is probably bad. You might be able to workaround it by disabling the device by opening PowerShell as Administrator and running the following:
gwmi win32_pnpentity -f "Description LIKE '%touch%'" | % { $_.Disable() }

The fix is to replace the digitizer, but the webcam malfunction might indicate a deeper fault. In either case, you won't know until you get someone in laptop repair to look at it.

Thank you! I deactivated the touchpad after doing a whole system restore because that was the only way I could get past the passcode. It still was doing the ghost dance and I tried another diagnosis, after the restore with the same error. But I must have pressed the hard reset (power button) too many times that it finally wouldn't start and got stuck on the initial Dell logo. A few months after the 1 year warranty expired... it probably was the motherboard as we were having problems with graphics before this.

Well we will be getting a new Asus with a 3 year extended warranty as it seems I am always having problems with a laptop soon after the 1 year period. Sony before this last Dell ... so is life.

Asus is a good choice. I used Asus motherboards when building custom computers and My 5 year old Asus laptop is still going strong.
