How to Remove HP Mobile Protection Sensor Driver hpdskflt.sys

HP Support were useless. I worked out a simple fix to remove hpdskflt associated with every drive as noted below. I left the HP Mobile Protection Sensor in Device Manger alone since it just reinstalls if you uninstall it. There should be an option to disable the device but HP do not allow this option. I also didn't fiddle with the other settings for hpdskflt.sys since the driver is associated with the HP Mobile Protection Sensor which cannot be uninstalled.

How to remove hpdskflt associated with all drives.
Delete the lower filter for hpdskflt at
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}
Reboot.

PS - do backup before you try this

Just a little remark, if you just do

Code:

reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}

Then you system won't boot, because it cannot access the harddrive. Recovery still works, which will reinstate the driver.

I'm digging a bit into the installation .inf files. I might update this post if I figure out how to remove this driver.

In my case the .inf file is at:

Code:

C:\Windows\System32\DriverStore\FileRepository\accelerometer.inf_amd64_25d7c1d09a3860dd\accelerometer.inf

I found an updated driver from August 31, 2019 at: ftp://ftp.hp.com/pub/softpaq/sp98001-98500/sp98412.html

Just delete the filter driver sub-entry not the entire registry entry!

So this ?

Code:

reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}\ /v lowerFilters

Edit: I did this, and the driver file is no longer attached to the harddrive, in Device Manager. But DriverView still shows it as loaded. Though I guess this means if I now remove the filter driver, it will not bluescreen Windows during boot.

Edit2: Yep that also works, remnants of the the driver are still there on the filesystem and registry, but I can live with that.

I left the driver installed in Autoruns else it just reinstalls itself. Keep checking since HP driver updates will reinsert the filter driver. I have advised HP of their lousy software engineering installing a sensor which isn't needed for a SSD.

Hi Steve,

Since we're on the same boat (I'm a ProBook user now, too) with this problem, I would like to suggest the following:
Although I clean installed my ProBook (just kept only the hp created EFI partition), to get rid of the hp bloatware, I also got the HP Mobile Data Protection Sensor for my 512 GB NVMe SSD. Apparently unneeded!

So I used this approach and disabled the device ACPI\VEN_HPQ&DEV_6007 in the group policy, checking the "Also apply to matching devices that are already installed" box.

Maybe you can try it too!

Good tip - where do you set that in Group Policy exactly?
