Touch Screen is CRAZY. Is there a command to disable touch screen while in safe mode? (Windows 10, Lenovo all-in-one)

I believe the Uninstall update button worked. I never saw any errors. It just didn't turn off the touch screen setting.

Great idea on the drivers. Only three 3rd party drivers came up on the C: partition (none on D:) One was bluetooth, one was Realtek (sound, right?), and third one is a Lenovo driver oem8.inf . Get-Driverinfo command says it is a "system interface foundation device" and seems to be in two parts: iMDriver and iMDriverV2, both a part of oem8.inf. 

Tomorrow, I'm going to browse around Lenovo's site to see if I can find out if this is the touch screen driver. I'm afraid to remove it, as I don't really know what it is, why it has 2 parts, or how to put it back. 

I'm seeing a lot of "ghost touch" problems on Lenovo's forums. Many people just turn off the touch screen, like I did. No solutions are posted. I suspect this is a Lenovo issue. 

I will come back to this tomorrow. I spent all day on it. Maybe I'll try the emergency administrative account first. 

Whether or not I can resolve it, your ideas have been excellent. Lenovo needs to steal you away at high salary for their forums.

You are unable to roll back the Updates that triggered this using the new Uninstall Updates button in Repair Mode?

If so see if you can uninstall using DISM command from Command Prompt also in Repair Mode:

You can also use DISM to uninstall the Touch driver which should not then work until the PC restarts and reinstalls it - unless you can also remove it's software package. See here: https://www.bleepingcomputer.com/forums/t/61786...

You could also enable the built-in hidden Admin account used in emergencies to see if it's stable, use it to sign in and create a new Local Admin Account to do the repairs from.

I cannot do most of the things on this list because I cannot log into my (administrative) account! I am stuck on the log in screen. 

The only thing I can do is use shift F8 to get to the advance startup options. I can get to Startup Repair, Startup settings, command prompt, uninstall updates (I DID THIS), UEFI FIrmware settings, System Restore (I DID THIS.)

Those advanced options required me to enter the administrative password and I was able to do that. But I can't put the password into the normal log in screen. The cursor jumps around crazily.

If I can't disable the touch screen from the command prompt, can I disable my user account log in from the command prompt?

Hi SM. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Guardian Moderator here to help you.

1. If this was caused by Windows Update(s) then you can check which were installed at Settings>Update & Security>Windows Update under Update History, then uninstall them from the link there, and immediately check for these again and hide with the Hide Updates tool explained here: https://www.howtogeek.com/223864/how-to-uninsta...

You can also go into Repair Mode by whichever method works here: https://www.tenforums.com/tutorials/2294-advanc... to use the new Uninstall Updates button in Advanced Troubleshoot Options: https://pureinfotech.com/uninstall-updates-adva...

You can also use System Restore from within Windows or the above Repair Mode to get back before the problem began, then check for Updates with the Hide Update tool and hide them: https://www.windowscentral.com/how-use-system-r...

4. Update your drivers and BIOS/UEFI firmware from PC or motherboard 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 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.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

5. go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account eliminate the frequent problem of account corruption as the cause. Then

6. If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1903 which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m....

Remember you have a one year Warranty from Lenovo for Support, Repair and Replacement, so I would use it if at all still possible to get this fixed. They may even be willing to see you a retroactive extension.

I hope this helps. Feel free to ask back any questions and keep me posted. If you will wait to rate my post, I will keep working with you until it's resolved.
