So, whether or not you’re on Home windows 11 Professional or Residence, should you aren’t utilizing BitLocker but, you must positively begin. Right here’s every part it’s good to find out about BitLocker and get it arrange proper now.
What’s BitLocker?
BitLocker is a safe disk encryption resolution that’s constructed into Home windows 11. When your PC makes use of BitLocker encryption, it shops all of the information on its inner storage system in encrypted form.
Fashionable Home windows PCs usually save the required decryption key to the PC’s Trusted Platform Module (TPM) for secure preserving.

BitLocker Drive Encryption vs. Home windows Machine Encryption
I’ve hinted at this a couple of instances already, however there are primarily two variations of BitLocker. There’s the “full” BitLocker expertise that we’re specializing in right here, which is named BitLocker Drive Encryption and is certainly one of greatest causes to improve to Home windows 11 Skilled.
Subsequent to that, there’s additionally one thing referred to as Home windows Machine Encryption, which makes use of a whole lot of the identical know-how to encrypt your PC’s storage in a simplified way — at the least, in some circumstances.
