You turn on your Windows computer expecting the normal login screen, but instead you see a blue BitLocker Recovery screen asking you to:

“Enter the recovery key to get going again.”

The computer may have worked perfectly the previous day, and you may not remember enabling BitLocker at all.

This situation can be alarming, particularly when important business documents, photographs, accounting data, or other files are stored on the computer. However, seeing the BitLocker recovery screen does not automatically mean that the hard drive or SSD has failed or that your data has been deleted.

BitLocker is a Windows security technology designed to protect encrypted data. Windows can request the 48-digit BitLocker recovery key when it detects a security-related change or cannot complete the normal trusted startup process.

This article explains why this happens, where to find the recovery key, what you should and should not do, and how to troubleshoot repeated BitLocker recovery prompts.

1. What Is BitLocker?

BitLocker is Microsoft's full-volume encryption technology included with supported editions and configurations of Windows.

It encrypts information stored on a drive so that someone cannot simply remove the SSD or hard drive, connect it to another computer, and access the files.

Depending on the Windows edition and device configuration, encryption may be provided through BitLocker Drive Encryption or automatically enabled Device Encryption.

BitLocker commonly works together with the computer's:

• TPM (Trusted Platform Module)
• UEFI firmware
• Secure Boot
• Windows boot configuration
• Microsoft account or organizational account
• PIN, password, or other authentication mechanisms

During a normal startup, these components establish that the computer is starting in an expected and trusted state.

If Windows cannot establish that trust, BitLocker may require the recovery key.

2. What Is a BitLocker Recovery Key?

A BitLocker recovery key is a special 48-digit numerical password that can unlock a BitLocker-protected drive when its normal unlocking mechanism is unavailable.

It normally looks similar to this structure:

XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX

The actual key must match the encrypted drive.

The BitLocker recovery screen may also display a Recovery Key ID.

Important distinction

The Recovery Key ID is not the recovery key itself.

The ID helps you determine which stored recovery key belongs to the affected computer or drive.

This is particularly important if your Microsoft account contains recovery keys for several computers.

3. Why Is Windows Suddenly Asking for My BitLocker Recovery Key?

The basic reason is:

BitLocker detected a condition in which it could not safely use its normal automatic unlocking process.

There are many possible causes.

4. BIOS or UEFI Firmware Update

A BIOS/UEFI firmware update is one of the common reasons a previously normal computer may suddenly display BitLocker recovery.

Updates may be installed manually or through:

• Windows Update
• Manufacturer update utilities
• Dell utilities
• HP utilities
• Lenovo utilities
• ASUS utilities
• Acer utilities
• Other OEM firmware tools

A firmware update can modify measurements or settings used during the trusted boot process.

BitLocker may therefore ask for additional verification.

Example

The laptop works normally on Friday.

A firmware update is installed.

After restarting, instead of Windows login, the user receives:

BitLocker Recovery

The SSD may be completely healthy. The firmware change triggered recovery.

5. TPM Changes or TPM Reset

The Trusted Platform Module (TPM) plays an important role in protecting BitLocker encryption keys.

BitLocker recovery can occur after changes involving the TPM, including:

• TPM reset
• TPM clearing
• TPM firmware update
• TPM disabled in BIOS
• TPM temporarily unavailable
• Motherboard replacement
• TPM ownership/configuration changes
• Firmware configuration changes

If the TPM no longer releases the required information during startup, BitLocker uses the recovery process as a security fallback.

6. Secure Boot Was Enabled or Disabled

Changing Secure Boot configuration can alter the trusted startup environment.

Examples include:

• Secure Boot enabled
• Secure Boot disabled
• Secure Boot keys changed
• Secure Boot reset
• UEFI settings restored to factory defaults

These changes can potentially trigger BitLocker recovery.

7. BIOS Settings Were Reset

A BIOS reset can happen intentionally or unexpectedly.

For example:

• BIOS defaults were loaded
• CMOS settings were reset
• Firmware update restored defaults
• Technician changed BIOS settings
• Hardware servicing altered firmware configuration

Settings associated with TPM, Secure Boot, UEFI booting, and boot order can consequently change.

BitLocker may interpret the resulting startup configuration as different from the previously trusted configuration.

8. Boot Order Changed

Suppose Windows normally starts from:

Windows Boot Manager → Internal NVMe SSD

But the firmware configuration changes to try:

USB → Network → Other Disk → Windows Boot Manager

Certain boot configuration changes can contribute to BitLocker recovery.

This can happen after:

• BIOS update
• BIOS reset
• Connecting another disk
• Changing boot settings
• Installing another operating system
• Using bootable recovery software

9. Windows Update or Firmware Update

Some Windows updates can coincide with changes affecting:

• Boot files
• Windows boot configuration
• Secure Boot
• TPM
• Firmware
• Recovery environment

Usually BitLocker handles normal Windows updates without intervention. However, particular update or firmware circumstances may result in a recovery prompt.

10. Hardware Changes

Significant hardware modifications can sometimes result in BitLocker recovery.

Examples include:

• Motherboard replacement
• TPM replacement/change
• SSD migration
• Storage controller changes
• Firmware changes
• Certain docking or boot configuration changes

A motherboard replacement is especially important because TPM functionality is generally associated with the system platform.

11. SSD or Hard Drive Moved to Another Computer

If a BitLocker-encrypted SSD is removed from one PC and connected to another PC, Windows may request the recovery key.

This is intentional.

Without encryption, a thief could bypass the original Windows login simply by removing the disk.

BitLocker helps prevent this type of offline access.

12. Dual-Boot or Bootloader Changes

Installing or modifying another operating system can change the startup environment.

Examples include:

• Installing Linux
• Installing another copy of Windows
• Modifying EFI partitions
• Changing Windows Boot Manager
• Rebuilding BCD
• Changing boot partitions

BitLocker may detect the changed boot environment and enter recovery mode.

13. Partition Changes

Changes involving system partitions may also affect startup validation.

Examples include:

• EFI System Partition modifications
• Recovery partition changes
• Partition cloning
• Disk migration
• Boot partition repair
• Partition resizing using third-party utilities

Not every partition change triggers BitLocker, but system/boot-related modifications require additional care on encrypted computers.

14. Automatic Device Encryption

A frequent source of confusion is:

“I never turned BitLocker on. Why is my drive encrypted?”

On supported modern Windows devices, Device Encryption may be enabled as part of device setup when hardware and account requirements are met.

Therefore, a user may have an encrypted Windows drive without remembering manually opening BitLocker Control Panel and enabling encryption.

This is why recovery-key storage should be checked before making major firmware or hardware changes.

15. Work or School Managed Computer

Business computers may have BitLocker enabled by an administrator through technologies such as:

• Microsoft Entra ID
• Microsoft Intune
• Active Directory
• Group Policy
• Other endpoint-management systems

In this situation, the recovery key may be stored within the organization's management environment rather than only in the user's personal Microsoft account.

Contact the company's IT administrator before making major changes.

16. How to Find Your BitLocker Recovery Key

There are several places where the recovery key may have been stored.

Method 1: Check Your Microsoft Account

If the PC was configured using a Microsoft account, the BitLocker recovery key may have been backed up to that account.

From another working computer or smartphone:

1. Sign in to the Microsoft account associated with the affected computer.
2. Open the recovery-key section.
3. Review the available BitLocker recovery keys.
4. Compare the displayed Key ID with the Key ID shown on the locked computer.
5. Locate the matching 48-digit recovery key.
6. Carefully enter the key on the affected computer.

If several keys are listed, matching the Key ID is important.

17. Check Your Work or School Account

If the device belongs to a company, school, or organization, the recovery information may be associated with the organization's account or device-management system.

Contact:

• IT administrator
• Microsoft 365 administrator
• Intune administrator
• Entra ID administrator
• Domain administrator
• Company's technical support team

Provide the computer name and recovery Key ID where appropriate.

18. Check Active Directory

In traditional Windows domain environments, administrators may configure Group Policy to back up BitLocker recovery information to Active Directory Domain Services (AD DS).

An authorized domain administrator may therefore be able to retrieve the recovery information for the computer.

19. Look for a Printed Recovery Key

When BitLocker was enabled, the person configuring the computer may have chosen to print the recovery key.

Check:

• Computer documentation
• Office IT files
• Safe
• File cabinet
• Device deployment documents
• Printed security records

20. Look for a Saved Recovery-Key File

The recovery key may have been saved as a text file.

Search other drives, USB drives, backups, or administrator storage for terms such as:

BitLocker Recovery Key

or

BitLocker

Do not assume the recovery key is stored on the encrypted Windows drive in an accessible form.

21. Check a USB Flash Drive

BitLocker recovery information may have been stored on removable media.

Check USB drives used when the computer was initially configured.

For business systems, ask the person or IT provider who originally configured BitLocker.

22. What Should I Do When the BitLocker Screen Appears?

Use the following approach.

Step 1 – Do Not Format the Drive

Do not format, initialize, repartition, or reinstall Windows simply because the recovery screen appeared.

Formatting can make recovery of the existing encrypted data impossible or much more difficult.

Step 2 – Note the Recovery Key ID

Write down or photograph the Recovery Key ID shown on the screen.

Do not publicly share the actual 48-digit recovery key.

Step 3 – Identify the Correct Account

Determine which Microsoft, work, or school account was used when the PC was configured.

Step 4 – Find the Matching Recovery Key

Check the appropriate account, organizational system, printed copy, saved file, or USB storage.

Step 5 – Enter the 48-Digit Key

Enter the matching recovery key.

If correct, BitLocker should unlock the drive and Windows can continue booting, assuming there is no separate Windows startup problem.

23. What If the Recovery Key Works?

If Windows starts successfully, do not immediately assume the issue is permanently resolved.

First determine why recovery was triggered.

Check whether the computer recently experienced:

• BIOS update
• Windows update
• TPM change
• Secure Boot modification
• Hardware servicing
• Motherboard replacement
• Boot-order change
• Firmware reset

Also make sure you have a secure backup of the recovery key.

24. BitLocker Keeps Asking for the Recovery Key on Every Startup

If you enter the correct recovery key and Windows starts but asks for it again after every reboot, there is likely an unresolved configuration issue.

Possible causes include:

• TPM configuration problem
• Secure Boot configuration mismatch
• BIOS configuration issue
• Boot configuration change
• Firmware issue
• TPM not functioning correctly
• BitLocker protectors requiring repair

Do not repeatedly modify BIOS options at random.

Record the original settings and determine what changed.

25. Check BitLocker Status

After successfully entering Windows, open Command Prompt as Administrator and run:

manage-bde -status

This displays information such as:

• Volume status
• Conversion status
• Percentage encrypted
• Encryption method
• Protection status
• Lock status
• Key protectors

You can inspect the configured protectors with:

manage-bde -protectors -get C:

This can help determine whether TPM and recovery-password protectors are configured.

26. Check TPM Status

Press:

Windows + R

Type:

tpm.msc

Press Enter.

Review information such as TPM status and whether Windows considers the TPM ready for use.

PowerShell administrators can also use:

Get-Tpm

Depending on the Windows version and environment, this provides information about the TPM's presence and readiness.

27. Check Secure Boot

Open System Information by running:

msinfo32

Look for:

Secure Boot State

On systems designed for UEFI/Secure Boot, confirm whether its state is consistent with the expected configuration.

Do not simply enable or disable Secure Boot as an experiment. Changing it can create additional boot or recovery complications.

28. Should I Clear the TPM?

Generally, do not clear the TPM simply because BitLocker asks for a recovery key.

Clearing the TPM removes information stored within the TPM and can affect:

• BitLocker
• Windows Hello
• PIN authentication
• Certificates
• Other security functions

Before clearing a TPM, ensure that required recovery information and backups exist and that you understand the effect on the particular computer.

For managed business computers, consult the administrator first.

29. Should I Disable BitLocker?

Not necessarily.

BitLocker provides valuable protection against unauthorized offline access to your data.

The better solution is normally to determine why recovery is being triggered and correct the underlying problem.

If you intentionally decide to decrypt a drive, understand that decrypting the volume removes BitLocker's at-rest encryption protection.

30. Suspend BitLocker Before Certain Planned Changes

For some planned firmware, hardware, or boot-related maintenance, temporarily suspending BitLocker protection can prevent an expected configuration change from unnecessarily causing recovery.

An administrator can inspect and manage BitLocker using Windows settings, Control Panel, PowerShell, or manage-bde.

For example, an administrator may use:

manage-bde -protectors -disable C:

After completing the planned maintenance and verifying that Windows starts normally, protection should be resumed.

Example:

manage-bde -protectors -enable C:

Important: Suspending BitLocker is different from decrypting the entire drive.

Use this procedure only when appropriate for the planned maintenance and your organization's security policy.

31. Can a BIOS Update Trigger BitLocker Even If Nothing Is Wrong?

Yes.

The recovery screen is not necessarily evidence of damage.

BitLocker is intentionally designed to challenge startup when measurements or security conditions differ from the expected state.

A legitimate firmware update can therefore result in recovery under some circumstances.

32. Does the BitLocker Screen Mean My SSD Has Failed?

No.

The appearance of a BitLocker recovery screen by itself does not establish that an SSD or HDD has failed.

However, a computer can have both encryption and a separate hardware/storage problem.

Warning signs of possible storage trouble include:

• SSD disappearing from BIOS
• Frequent I/O errors
• SMART warnings
• Windows repeatedly crashing
• Disk detection becoming intermittent
• Extremely slow disk access
• Read/write errors

Those symptoms require separate diagnosis.

33. Can I Recover Files Without the BitLocker Recovery Key?

This is one of the most important questions.

Properly implemented BitLocker encryption is specifically intended to prevent unauthorized recovery of encrypted information without valid unlocking credentials.

If the drive is locked and you do not possess an applicable password, recovery key, startup key, or another valid configured protector, ordinary file-recovery software cannot simply decrypt the files.

Tools that recover deleted files or damaged partitions do not bypass BitLocker encryption.

Therefore, finding the legitimate recovery key is extremely important.

34. Can Data-Recovery Software Bypass BitLocker?

Generally, no.

Applications designed for:

• Deleted file recovery
• Partition recovery
• RAW disk recovery
• NTFS repair
• Photo recovery

cannot magically decrypt a correctly encrypted and locked BitLocker volume.

If the underlying disk is physically failing but the BitLocker key is available, professional recovery may sometimes involve creating an image of the failing media and then working with the encrypted data using legitimate credentials.

Encryption and physical data recovery are separate problems.

35. What Happens If I Format a BitLocker Drive?

Formatting creates a new filesystem or prepares the volume for reuse.

It does not provide a legitimate method for recovering the previously encrypted files.

If the existing information matters, do not format the drive simply to make the computer bootable.

First exhaust legitimate recovery-key options.

36. What If I Reinstall Windows?

A clean Windows installation may overwrite partitions and data.

It may make the computer usable again, but that is very different from recovering the previous encrypted files.

If you need the existing data:

Do not reinstall Windows until the data-recovery situation has been evaluated.

37. What If I Cannot Find the Recovery Key Anywhere?

Check every legitimate possibility before considering data loss:

1. Personal Microsoft accounts
2. Work Microsoft account
3. School account
4. Microsoft Entra ID environment
5. Active Directory
6. Intune/device-management records
7. Printed copies
8. USB drives
9. Saved text files
10. Password/document management systems
11. IT administrator
12. Previous IT service provider
13. Person who originally configured the computer

Also make sure you are checking the correct account.

People commonly have multiple Microsoft accounts.

38. Microsoft Account vs Local Windows Account

A computer may use:

• Microsoft account
• Local Windows account
• Work account
• School account
• Domain account

The location of the recovery key depends on how encryption was configured and how the key was backed up.

Having a local Windows account does not guarantee that BitLocker is disabled.

39. BitLocker After Motherboard Replacement

Motherboard replacement is a particularly important scenario.

Because TPM functionality is associated with the platform, replacing the motherboard can change the security environment used to unlock BitLocker.

Before motherboard servicing, when possible:

• Back up important data.
• Verify the recovery key.
• Record the recovery Key ID.
• Follow manufacturer and organizational guidance.
• Suspend BitLocker if appropriate for the maintenance.

If the motherboard has already been replaced, the recovery key may be required to access the existing encrypted Windows installation.

40. BitLocker After BIOS Reset

If BitLocker appears immediately after resetting BIOS/UEFI settings, compare the current firmware configuration with the previous known-good configuration.

Important areas may include:

• TPM
• Secure Boot
• UEFI/Legacy boot mode
• Boot order
• Storage-controller settings

Avoid changing storage-controller modes blindly, because an incorrect setting can prevent Windows from booting.

41. BitLocker After Replacing the CMOS Battery

Replacing a CMOS/RTC battery does not directly decrypt or encrypt the drive.

However, firmware settings may be reset during maintenance, which can indirectly change the startup environment and result in BitLocker recovery.

Check whether BIOS defaults were restored.

42. BitLocker After Cloning an SSD

Cloning an encrypted Windows installation requires careful planning.

Changes to:

• Partition identifiers
• EFI partitions
• Boot configuration
• TPM association
• Startup measurements

may result in recovery.

Before migration, ensure that the BitLocker recovery key is backed up and verify that the backup is usable.

43. BitLocker and Windows Automatic Repair

Sometimes a user sees both:

• BitLocker Recovery
• Windows Recovery Environment
• Automatic Repair

These are not necessarily the same problem.

BitLocker may require the drive to be unlocked before Windows recovery tools can access the encrypted Windows installation.

After unlocking the volume, a separate boot or operating-system problem may still need repair.

44. BitLocker and Safe Mode

Changing startup settings or entering recovery environments can sometimes interact with BitLocker-protected systems.

Before making advanced boot configuration changes, make sure the recovery key is available.

This is particularly important on business-critical computers.

45. How Businesses Should Manage BitLocker Recovery Keys

Organizations should not depend on employees remembering where a recovery key was saved.

A managed BitLocker deployment should include centralized recovery-key backup and documented procedures.

Depending on the environment, organizations may use:

• Microsoft Entra ID
• Microsoft Intune
• Active Directory
• Enterprise endpoint-management systems

The organization should establish procedures covering:

• Key escrow
• Recovery authorization
• Device identification
• Employee departure
• Hardware replacement
• BIOS updates
• Motherboard replacement
• Lost/stolen devices
• Key rotation where appropriate

46. Important Security Warning

Treat a BitLocker recovery key like a sensitive credential.

Anyone who obtains the correct recovery key and physical access to the encrypted drive may potentially unlock it.

Therefore:

• Do not post recovery keys on public forums.
• Do not include them in screenshots shared publicly.
• Do not send them to unknown support agents.
• Do not store them unprotected beside the computer.
• Do not publish recovery-key photographs.
• Use approved secure storage for business recovery information.

47. Preventing Future BitLocker Recovery Problems

You cannot guarantee that a legitimate recovery prompt will never occur, but you can greatly reduce the risk of being locked out.

Recommended practices include:

• Keep a verified recovery-key backup.
• Know which account contains the recovery key.
• Keep important files backed up separately.
• Check BitLocker before firmware maintenance.
• Do not randomly modify BIOS settings.
• Avoid clearing the TPM without preparation.
• Document motherboard and TPM servicing.
• Use centralized key management for business computers.
• Verify recovery information before disk migration.
• Ensure IT personnel understand BitLocker before hardware repairs.

The most important rule is:

Never wait until the BitLocker recovery screen appears before checking whether you have the recovery key.

48. Quick Troubleshooting Checklist

If your computer suddenly asks for a BitLocker recovery key:

1. Do not format the drive.
2. Do not reinstall Windows yet.
3. Record the Recovery Key ID.
4. Check your Microsoft account.
5. Check your work/school account if applicable.
6. Contact your organization's IT administrator.
7. Search for printed or saved recovery keys.
8. Enter only the key matching the Key ID.
9. After Windows starts, check BitLocker status.
10. Investigate recent BIOS, TPM, Secure Boot, Windows, or hardware changes.
11. Back up important files.
12. Securely verify and preserve the recovery key for future use.

Frequently Asked Questions (FAQ)

1. Why did BitLocker suddenly appear?

BitLocker may enter recovery when Windows detects an unexpected change involving TPM, UEFI/BIOS, Secure Boot, boot configuration, firmware, or hardware.

2. Does BitLocker recovery mean my computer has been hacked?

No. A recovery prompt alone does not prove that the computer was hacked. Legitimate firmware and hardware changes can trigger it.

3. Why am I getting BitLocker when I never enabled it?

Some compatible Windows devices can use Device Encryption, and encryption may have been enabled during setup or by an organization.

4. How many digits are in a BitLocker recovery key?

A standard BitLocker recovery password contains 48 numerical digits.

5. Is the Recovery Key ID the actual recovery key?

No. The Key ID identifies the appropriate recovery key. It cannot itself unlock the volume.

6. Where can I find my BitLocker recovery key?

Possible locations include a Microsoft account, work/school account, Entra ID, Active Directory, organizational management system, printed copy, USB drive, or saved file.

7. Can Microsoft tell me my BitLocker recovery key?

Microsoft cannot simply generate a replacement key for an encrypted drive. Recovery depends on whether the valid recovery information was previously backed up to an accessible location.

8. Can a BIOS update trigger BitLocker?

Yes. Firmware changes can sometimes result in BitLocker recovery.

9. Can a Windows update cause BitLocker recovery?

Certain update or firmware-related changes can coincide with recovery, although ordinary updates generally proceed without requiring a recovery key.

10. Can changing Secure Boot cause BitLocker recovery?

Yes. Secure Boot configuration changes can alter the trusted startup environment.

11. Can clearing the TPM cause BitLocker problems?

Yes. Clearing the TPM can remove security information and may cause BitLocker and other authentication technologies to require recovery or reconfiguration.

12. Should I clear TPM to fix BitLocker?

Not as a first troubleshooting step. Verify recovery information and determine the actual cause before making TPM changes.

13. Can replacing the motherboard cause BitLocker recovery?

Yes. A motherboard replacement can significantly change the TPM/security environment.

14. Can moving an SSD to another PC trigger BitLocker?

Yes. BitLocker is specifically designed to protect encrypted data from unauthorized offline access, including attempts involving another computer.

15. Can I bypass BitLocker with data-recovery software?

Ordinary data-recovery software cannot bypass properly implemented BitLocker encryption without valid unlocking credentials.

16. Will formatting remove BitLocker?

Formatting may prepare the drive for reuse, but it does not recover the previous encrypted files. If you need the old data, do not format the drive.

17. Will reinstalling Windows fix BitLocker?

A clean installation may make the computer usable by replacing the previous installation, but it may destroy or overwrite access to existing data. It is not a recovery method for encrypted files.

18. What if I have multiple BitLocker recovery keys?

Compare the Recovery Key ID displayed by the locked computer with the IDs associated with your stored recovery keys.

19. Why does BitLocker ask for the key every time I restart?

A persistent TPM, firmware, Secure Boot, or boot-configuration problem may be preventing automatic unlocking. The underlying configuration should be diagnosed.

20. Should I disable BitLocker permanently?

Usually not simply because recovery occurred once. BitLocker provides important data-at-rest protection. Investigate why recovery occurred and maintain a secure backup of the recovery key.

21. Does BitLocker protect against someone stealing my laptop?

Yes. One of its primary purposes is to make data on an encrypted drive difficult to access without valid authorization if the device or drive is stolen.

22. Does BitLocker replace normal backups?

No. Encryption and backup solve different problems. BitLocker protects confidentiality; backups protect against deletion, corruption, hardware failure, ransomware, and other forms of data loss.

23. Should businesses keep BitLocker keys centrally?

Yes. Organizations should generally use an appropriate centralized recovery-key management process rather than relying solely on individual users.

24. Should I suspend BitLocker before a BIOS update?

For planned firmware or hardware changes, BitLocker suspension may be appropriate depending on the manufacturer instructions, Windows configuration, and organizational security policy. Always ensure the recovery key is backed up first.

25. What is the safest thing to do before repairing a BitLocker-enabled PC?

Back up important files, verify the recovery key, document its Key ID, check encryption status, and understand what hardware or firmware changes will be performed.

Conclusion

A sudden BitLocker Recovery screen does not necessarily mean that Windows is corrupted, the SSD has failed, or your computer has been compromised.

In many cases, BitLocker is doing exactly what it was designed to do: preventing automatic access to an encrypted drive after detecting an unexpected change in the computer's trusted startup environment.

Common triggers include BIOS/UEFI updates, TPM changes, Secure Boot changes, firmware resets, boot configuration changes, motherboard replacement, and storage migration.

The most important precautions are simple:

Do not format the drive, do not reinstall Windows just to bypass the screen, and do not clear the TPM without understanding the consequences.

Instead, locate the correct 48-digit BitLocker recovery key, match it using the Recovery Key ID, unlock the computer, and then investigate what caused recovery.

For both home and business users, maintaining a verified and securely stored BitLocker recovery key is an essential part of Windows data protection.
