(Just a heads up, I'm by no means tech-savvy.)

I've had an issue with my Dell laptop that runs Windows 10, I've spent a good chunk of today figuring out, with no solution and a possible new issue. With no warning, my laptop's touchpad started behaving strangely today. It would change sensitivity in the middle of using it and the two-touch scrolling and zooming won't work. Nothing in the settings changed nor have I downloaded anything between yesterday and opening my laptop today.

I assume it had something to do with the drivers connected to the touchpad. When I go to Device Manager, both the HID-compliant touchpad and HID-compliant mouse with the same file location (I2C HID Device), both their Device Statuses stated: "Currently, this hardware device is not connected to the computer. (Code 45) To fix this problem, reconnect this hardware device to the computer".

It's the built-in touchpad, so I had no way as far as I could research to just "reconnect this hardware device". I attempted to update the drivers to no avail. I tried many other different solutions, restarting my laptop various times within the process, including the official Window's support. One of the solutions listed was "try uninstalling your touchpad driver: open Device Manager, right-click (or press and hold) the touchpad driver, and select Uninstall. Restart your device and Windows will attempt to reinstall the driver."

I didn't know which one it meant, so i uninstalled both drivers, after restarting, neither were found in the Device Manager. My touchpad is still functional, though it's still got the issues mentioned before. Now I'm trying to find a place to download the touchpad drivers, none of which so far are "compatible" with my model. I even tried the part of Dell support where you directly put in your model number and such to get a direct diagnosis, but I couldn't find any touchpad driver.

I'm finally at the end of my wits and am here to look for direct answers. Who knows, with how inconsistent Windows 10 is and problems seem to come and go, maybe I could or could have just waited and the problem will fix itself. But I get very concerned over hiccups like this in case there's a bigger issue, and I know so little about this stuff that I can jump into doing things without fully thinking and possibly make things worse.
