Best Answer

On Windows 10 Home (Where Bit Locker Encryption does not show) I was just able to stop encryption. open start>>setting, then type "bitlocker" on search bar (In Setting not Control Panel) Now you will find "Change Device Encryption Settings" and when you open that tab you will find turn off option, or go to bitlocker settings.

After that go to command Promt(or PowerShell) by Admin

Disable-Bitlocker -MountPoint "C:"

in my case it was C drive

manage-bde -off "C:"
RESTART

System will innitialize bios setting and Flash Setting on restart.

There is more. It will start Decrypting. You can check Encryption % using below cmd

Disable-Bitlocker -MountPoint "C:"

You may check DiskManagement in Computer Management for the same.
