These solutions for typical BitLocker issues will help you protect your data whether you're having difficulty encrypting or decrypting your hard drive.


BitLocker is a well-known encryption technology for Windows users, and although there have been sporadic problems with it acting uncooperatively.

Would You Kindly Describe BitLocker?


BitLocker is probably something you know if you respect data security. If this is all new to you, though, allow me to quickly summarize.


BitLocker encryption is a complete solution designed especially for Windows. Not only data but your entire hard drive is protected by it. To access the encrypted drive using BitLocker, one needs a password or smart card. Lost initial passwords are rather common. The only way to decrypt the Windows drive in such a case is to use the BitLocker recovery key that was given to you during setup.


Accessing a hard drive encrypted by BitLocker's Advanced Encryption Standard (AES) algorithm is difficult without the right credentials.


Businesses use BitLocker a lot to protect data. Despite its great security, BitLocker is prone to bugs. Disk encryption, BitLocker activation, and recovery key location could be challenging.


Resolving BitLocker Issues on Windows
