Your data insights determine the success of your organization. Thus, you would keep it safe by setting up passwords and users. It is terrible if you lose your device, and then anybody can hack it and create a security breach. To resolve it, you would use an encryption service similar to BitLocker. So, if you are wondering what BitLocker is and How to Enable BitLocker on Windows 10, then we have got you all covered! 

What is BitLocker

Suppose you want to protect your data from thefts and security breaches; you can encrypt your hard drive and thus its contents. Therefore, when you want to protect your Windows Operating System, then BitLocker works well. It is a drive encryption software from Microsoft for Windows PC. The service refrains unauthorized users from accessing your data providing vital security to it. To access the data, you must go ahead with the Recovery key. No one can hack your disk's data. So, even if someone steals your PC or a similar case, they would not see it! 

How Does BitLocker Work 

When you want to protect your hard drive, you can leverage the power of BitLocker for it. It works on TPM (Trusted Platform Module) that stores particular keys that you can use to authenticate your hard drive. If you do not have TPM installed on your computer, you can also use it. Mostly, it is present when you purchase it. If you do not have a TPM installed on your device, you can still access BitLocker if you have a recovery key. However, you must have a USB startup key. But if you have TPM installed on your PC, then BitLocker would work better as an integrity verification system is much more advanced than a USB startup key. Hence, you get better encryption with a TPM. 

The coolest part of BitLocker is that you can even lock your system's Startup till you want it. This system will automatically unlock when you enter a PIN or use a drive containing a startup key. These are two methods, and you can select one that suits your requirements. 

BitLocker protects your hard drive and ensures advanced security if you have a Trusted Platform Module on a PC. The feature is available in Windows Vista and its higher OS versions. For using BitLocker, you need a Windows Pro or Enterprise Edition. So, if you want to use it on Home editions, we have fixes for the same. 

As it is a Microsoft service, you do not need to pay additional costs to use it. The most brilliant feature of BitLocker is that it provides an advanced level of encryption with TPM, yet it does not affect the read and write speed of hardware or software. So even if you are a novice, you can set up quickly. You should have two partitions on your hard drive. It is mandatory as one partition will do the encryption task, and the other is required for integrity verification.

You might not be aware, but BitLocker does provide hardware encryption for critical situations, but it is not a foolproof plan. Your data will be safe only if your system is unlocked and logged in. But it will not protect your encrypted data always. So, if you have any backup plan for hard drive data encryption, you should not abandon them. 

How to Use BitLocker in Windows

Therefore, you need a Windows Professional, Enterprise, or similar edition to use it. However, some credible methods do let you use BitLocker in Windows.
