Resolution
Important Note: It is not usually recommended to decrypt drives. Decrypting drives could leave the system in a vulnerable state and should be done only with special considerations such as the following:
*Where the machine is located (inside of a secured location our out in the wild).
*What the reason for decrypting is? Is it a troubleshooting step?
Typically, decrypting is not necessary for most troubleshooting and may be more risky than it's worth.
*Are you decrypting to upgrade Windows? This is not needed as our software has functionality to accommodate this seamlessly.
