Most touchpad settings suddenly missing/moved

Go Settings, Devices, Mouse, Additional mouse options, Touchpad.

That's just the problem: there isn't a separate Touchpad tab under Mouse Properties (the dialog that came up from the "Additional mouse options" link, which I have been in and out of throughout this whole process), or at least there isn't on my machine.

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

The surest way to fix a touchpad is to first assure you have the very latest touchpad driver from the HP download page here for your exact Serial and Product number:
http://support.hp.com/us-en/drivers. The most basic thing we need to learn to maintain a PC is how to keep the latest manufacturer's drivers current. Windows Update drivers are never enough.

While doing this also 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.

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 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.

See the troubleshooting steps here: https://support.microsoft.com/en-in/help/402786...

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

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:

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:

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.

stupid answer.  He already told you he does not have the settings you suggest.

all you get is sensitivity - all the rest of the controls are gone - as he said in his original  question

This is a useless answer:

First: we have no way of determining what touch pad we have because all the settings are gone.  Second: The device does not appear in Devices, there is no "touch-pad" listed as a device either under devices or human interfaces.  So there is not way to determine what the device is let alone have any settings.  If you go the the Synaptics  website thinking you may be able to download drivers there - forgetaboutit.  There are NONE. 

Third:  I have a dell and if you go to the dell website - they don't have drivers available.  So ****.  

Fourth: And when is Microsoft going to pay me for the 50 or so hours I have had to "donate" to finding solutions to all the problems each and every update causes???

This is not an inconvenience - this has made my laptop keyboard useless for doing anything fast.  Time is money and I'm going to start billing

I NEED A REAL ANSWER NOW.
