accelerometer error - reinstall of HP 3D DriveGuard didn't work

[Glookie]

I ran the Windows Update weekend of 6/17/2017. And it destroyed my OS! Among other problems, I keep getting a popup on startup which read "AccelerometerST.exe - Application Error." Error code is 0xc00007b.

I uninstalled HP 3D DriveGuard. Restarted. Went into the HP Support page, allowing it to automatically select my laptop. (This took a while as both Chrome and Edge keep crashing.) Then I downloaded & installed HP 3D DriveGuard v 6.0.28.1, but I'm still getting the same error. DriveGuard is showing up in my list of programs.

BTW, my password manager is not working. Neither is Veracrypt. Some of my shortcuts are broken, too.

Great work, Microsoft.

Any idea of how I can resolve the DriveGuard issue, to start with?

Thank you.

Thank you for your quick response. That worked!

?Have you ever seen the other major problem I've been experiencing? When I close the lid and then reopen it, I used to see my lock screen. Since the update, when I close the lid and then reopen it, I just have a black screen. No keys or touchpad responds. I have to hold down the power button for about 10 seconds in order to shut it down so I can restart the PC. Of course, I lose any unsaved data. So I can't close the lid now.

Anyone have any suggestions?

Thanks again.
