BitLocker is a Windows security feature designed to protect data by encrypting drives, making it inaccessible to unauthorized users. This document provides an overview of BitLocker, its types, recovery methods, and potential activation reasons.

What Is It?

There are two main types of BitLocker: Device Encryption, which is enabled by default and covers the entire device, and BitLocker Drive Encryption, which allows for custom configurations in advanced scenarios. (SOURCE:  1).

Device encryption: if your Windows 11 device senses that an unauthorized user is trying to access your data, it will immediately encrypt it, which results in a blue screen.  There are two types of BitLocker, and they are as follows:

  • Device Encryption:

This is set by default and will cover your entire device.

  • BitLocker Drive Encryption:

This is typically used in more advanced scenarios, and the functionalities of it can be custom configured.

An actual example of the BitLocker is seen below:

How To Recover from BitLocker

The only way to recover from a BitLocker blue screen, is to enter a “Recovery Key”.  Microsoft defines this as a unique 48-digit numerical password that can be used to unlock an encrypted drive.

An example of if it can be seen below:

Now, you might very well be asking this question:  “If I am impacted by BitLocker, how do I find the Recovery Key?”  There are two scenarios in which you could access it, which are:

  • Check your Microsoft account:

If you have this kind  of account, and  the device that was impacted by BitLocker was registered into it, you need to follow these steps:

  • If possible, access a different device.
  • Go to a web browser, and access this link:

https://account.microsoft.com/devices/recoverykey

  • Sign into your account and locate the Recovery Key. This is illustrated below:

  • Work or school:

If you have a device that was issued to you by your school or place of employment, contact your  IT Support team to help you find your Recovery Key to get your device back up and running.

It is important to note that in both scenarios just described, if you do not know who the device is registered to, the latest version of Windows 11, which is version 24H2, the BitLocker screen will actually provide a very small hint as to who the owner is.

In the most extreme, worst-case scenario, if you are unable to locate your Recovery Key, you will then have to reset your device.  If you do this you will be able to gain access to your device but all your files will be permanently deleted.  This only underscores the sheer importance of backing up all your files on a regular basis.

How Did It Get There?

Another valid question that you may be asking at this point is:  “How was BitLocker even on my device?”  Here are four answers:

  • Your device already came with it installed. In this case, the Recovery Key will be automatically deployed into your Microsoft account.
  • If you have a work or school issued device, it is possible that the IT Support team manually installed it.
  • If you have a device that has been issued only by your employer, then it is also likely that BitLocker was installed by their Security Policy.

Conclusions

It is important to keep in mind that BitLocker may be activated for other reasons as well, which are hard to determine.  For instance, over time, some of the files in your device could have been corrupted, or your device attempted to automatically download a software patch with which it did not “agree”.
