Dynamic Volume Manager is a kernel device driver. In Windows 10 it is starting by the operating system Boot Loader as a part of the driver stack for the boot volume. If Dynamic Volume Manager fails to load or initialize, Windows 10 attempts to record the error details into Event Log and restart the PC, using the Last Known Good configuration. If the Last Known Good configuration cannot be applied or working improperly, Windows 10 startup process halts with a Stop error. If you disable or delete the volmgrx service, Windows 10 won't start.
Restore Default Startup Configuration for Dynamic Volume Manager

2. Save the Win10_volmgrx_Service_Startup.cmd file to a local storage device.

The volmgrx service is using the volmgrx.sys file that is located in the %WinDir%\System32\drivers folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
