How to Enable or Disable BitLocker Encryption in Windows

BitLocker Drive Encryption is a data security tool that encrypts your disk to help keep your data safe. The BitLocker feature will provide maximum protection when you use it with the Trusted Platform Module (TPM) version 1.2 or later.

There is no guarantee that if you pay the ransom, you will get the unlock key to regaining access to the files that the ransomware encrypted.

How to Encrypt a USB Flash Drive with BitLocker Windows 11

How to Encrypt a USB Flash Drive with BitLocker Windows 11

Encryption is one way to protect your data so that only certain people who have the key can access it. If you have sensitive data, protecting that data by encrypting it will increase the security of that data. For example, if you have sensitive data stored on your computer and you do not encrypt it, then other people will easily retrieve your data by moving your hard drive to another computer as a second drive. However, if your drive is encrypted, when they try to open it will be asked to enter the encryption key. Without the key, they will not be able to find out the contents of the drive. Likewise, if you encrypt a USB Flash drive, only the person with the encryption key can know its contents. So you can safely store the USB Flash drive or if you send the USB Flash drive to a co-worker via courier, you can send the key to a co-worker via email or other media.
