How it Works:
- Disable-BitLocker removes all key protectors from the specified volume and begins decrypting its contents.
- -MountPoint "C:" specifies which drive letter to target - replace this with whatever volume you actually want to decrypt.
- If the operating system volume has automatic unlocking keys configured, this command won't proceed until those are removed first.
Pro Tip:
To disable BitLocker on every encrypted volume on the machine at once:
$BLV = Get-BitLockerVolume
Disable-BitLocker -MountPoint $BLV
