If this driver is loaded, windows update will crash on reboot. I have to uninstall diskcryptor whenever i want to update any of my windows 10 pcs.
I hope this saves someone the the trouble I had narrowing down my crashes!

I've had diskcryptor installed for years. Then this file was just found by Malwarebytes, flagged as malware. I quarantined without checking out carefully and windows reboot crashed. Windows had to be completely reinstalled. Do not choose to quarantine!
