Hi
Sounds like you are having it rough.
Hang in there, it will get sorted.
As you have found out by the harshest means possible, "Reformat", this is a driver issue.
Can you roll back the drivers and try changing the group policy as shown below.

How to Stop Windows 10 From Automatically Updating Hardware Drivers
Is there any news on this issue? My wife's laptop has the same problem. Builtin keyboard and touchpad stopped working sometime during the last few months, and she has been using it with an USB keyboard and mouse. Of course, now she has to go on a long business trip and we haven't been able to fix this problem.
The builtin keyboard+mouse work as long as we're in the BIOS menu or the HP Diagnostic tool. I have tried to reinstall both the newest and some older versions of all the chipset drivers available on the hp support site, and also the ELAN Touchpad driver. (For the keyboard I don't see any special driver available; windows installs the standard PS/2 keyboard driver).
Sensors work, the device display rotates when I turn it around.
The laptop is not in the Windows Tablet Mode and all boxes in Ease of Access are unchecked.
The model number is hp Pavilion x360 13-u102ng, Windows 10 Home.
And yes, all latest updates from Windows Update and HP Support Assistant are installed, including BIOS and firmware updates.
For some silly reason there were no restore points created so cannot try that. (I have now enabled that so in the future it will help.)
Windows has an option to turn off the feature where it updates drivers. This may allow you to use the keyboard.

I can confirm that this situation is a super tricky driver issue.
Yesterday I tried the "reset my PC" option offered by windows 10. This did not help. Then I tried the "Refresh" option that has been available from Windows Defender since the last big update. It took a while to complete so I left the computer alone and went out. When I came back, it was finished and TA-DA the builtin touchpad and keyboard were working. I was happy with that and went to bed. This morning they did not work again! I checked and yeah! Windows had installed three updates between now and then, one of them being the large cumulative June 2017 update. So I missed my time window of trying to make Windows not update oem drivers automatically. Sigh.
So I tried Refresh again. And disabled networking (by making Windows forget all the WiFi passwords) to make sure it will not auto update anything. This time it did not help! And when it was done, the windows update history says that the June 2017 cumulative update "kb4022405" is already applied and furthermore it cannot be removed!
At this point I am no closer to finding out which driver is the issue (and i believe i have tried reinstalling any and all that seem even remotely relevant). My only remaining option is to restore the backup I did just before I started all these excercises, and then do the "Refresh" again, in a hopeful attempt to repeat the success I enjoyed last night - and this time be 101% sure the computer cannot do any automatic updates....
Of course my wife goes for another business trip in a day so as I probably don't manage to fix this by then, it will be another few weeks when I will have the opportunity to try again ....
This gets weirder! Last night Microsoft pushed an update to my wife's machine and in the morning the keyboard and touchpad were working. Great, awesome! ... however, by this evening they had stopped functioning again.

6) shutdown /r (you will reboot the computer so that it is in clean boot)
Evaluate the performance on your computer in clean boot during typical use.
Are the boots faster or slower?
Are the shutdowns faster or slower?
How has the audio and video performance changed? Is it better, worse, or the same?
How has the use of the keyboard changed? Is it better, worse, or the same?
How has the use of the mouse changed? Is it better, worse, or the same?
Continue using clean boot indefinitely to monitor performance.
8) type control in the left lower corner search > click on control panel > click on large or small icons > click on troubleshooting > on the left pane click on view all > run the following windows troubleshooter:

I suffered through this same issue and after multiple reinstalls I found out what the issue was; it turns out that the Intel Integrated Sensor Solution was the culprit. If you go into Device Manager>System Storage and disable Intel Integrated Sensor Solution it should fix the issue after a restart.
Thanks a lot Bitterblod, disable the component: "Inter integration sensor solution" and restart, works form
regards.
