Fix Access Denied When Opening BitLocker Encrypted Drive
Fixed: The BitLocker Drive is not Accessible & Access is Denied
Want to unlock your BitLocker drive in your Windows 10 laptop, but a prompt is popped out to tell you that the drive isn't accessible and access is denied? At that time, you may consider to access the BitLocker drive by formatting it. However, this method will not only erase the data in the BitLocker drive, but also remove the BitLocker from your drive. Therefore, it's recommended to fix the access denied error instead of formatting the BitLocker drive and here is the way to fix the error that the BitLocker drive is not accessible and access is denied in Windows 10.

BitLocker was first introduced in Windows Vista and still exists in Windows 10. It was implemented exclusively for Windows and has no official support in alternative operating systems. BitLocker can utilize your PC's Trusted Platform Module (TPM) to store its encryption key secrets. In modern versions of Windows such as Windows 8.1 and Windows 10, BitLocker supports hardware-accelerated encryption if certain requirements are met (the drive has to support it, Secure Boot must be on and many other requirements). Without hardware encryption, BitLocker switches to software-based encryption so there is a dip in your drive's performance. BitLocker in Windows 10 supports a number of encryption methods, and supports changing a cipher strength.
Note: In Windows 10, BitLocker Drive Encryption is only available in the Pro, Enterprise, and Education editions. BitLocker can encrypt the system drive (the drive Windows is installed on), and internal hard drives. The BitLocker To Go feature allows protecting files stored on a removable drives, such as a USB flash drive.

To enable access to a BitLocker-protected removable drive in a Remote Desktop Session, Windows 10 offers you at least two methods, a Group Policy option, and a Group Policy Registry tweak. The first method can be used in editions of Windows 10 that come with the Local Group Policy Editor app. If you are running Windows 10 Pro, Enterprise, or Education edition, then the Local Group Policy Editor app is available in the OS out of the box. Alternatively, you can apply a Registry tweak. Let's review these methods.
Allow Opening BitLocker Encrypted Removable Drive over RDP

If you have a BitLocker encrypted USB stick connected to a computer that you are accessing over the Remote Desktop (RDP), you will see the "Access Denied" message once you try to unlock the drive. These are security defaults in Windows 10 which limit access to encrypted drives. Here is how to configure the OS to open such encrypted removable drives.
