I did not locate this executable in my Windows folder. It was located in Programs (x86) in an HP sub-directory. All AV scans confirmed it was not a threat.

Locks up Hard Drive if you drop your Laptop to insure no files are corrupt on the hard drive. So that if you need a new laptop you have your files.
Uninstall HP 3D DriveGuard then reinstall.

Best practices for resolving AccelerometerSt issues

A clean and tidy computer is the key requirement for avoiding problems with AccelerometerSt. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
