Data encryption is a cornerstone of privacy and security on Windows 10 and 11. Whether you rely on BitLocker, EFS (Encrypting File System), or third-party tools, encryption protects sensitive data from unauthorized access. However, problems can arise: corrupted keys, inaccessible drives, failed decryption attempts, and more. This article presents ten time-saving ways to troubleshoot and repair data encryption issues in Windows, making the process practical for both beginners and advanced users.
Beginner-friendly Repairs and Tips
1. Check Encryption Status and Basic Settings
Start by confirming whether your drive or files are encrypted. For BitLocker, open Control Panel, go to System and Security, and select BitLocker Drive Encryption. For EFS, right-click a file, choose Properties, click Advanced, and check if “Encrypt contents to secure data” is checked.
If encryption is not enabled or seems inconsistent, toggle encryption off and on to refresh settings. This simple action can fix minor glitches.
2. Use the Windows Troubleshooter
Windows offers built-in troubleshooters that can automatically detect and fix some encryption-related issues.
Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters. Run any available troubleshooters related to security, accounts, or storage. Often, Windows will suggest specific actions or fixes.
3. Restart and Update Windows
Many encryption problems stem from pending updates or incomplete system changes. Save your work, reboot your PC, and ensure you’ve installed the latest Windows updates via Settings > Update & Security > Windows Update. This clears out many common software-related obstacles.
4. Recover BitLocker or EFS Keys
If prompted for a recovery key, don’t panic. You may have saved your BitLocker recovery key to your Microsoft account, a USB drive, or a printed copy. Visit https://account.microsoft.com/devices/recoverykey to check your stored keys.
For EFS, check any exported certificate backups or previous system backups—these can save you from permanent data loss.

5. Repair System Files
Corrupted system files can interfere with encryption. Use the following commands to check and repair your system files:
Open Command Prompt as Administrator.
Type sfc /scannow and press Enter.
Wait for the scan to finish. If issues persist, run DISM /Online /Cleanup-Image /RestoreHealth.
These actions often fix hidden problems affecting encryption.
6. Re-enable BitLocker or EFS
Occasionally, disabling and re-enabling encryption resets problematic settings.
For BitLocker:
– Open Control Panel > BitLocker Drive Encryption.
– Turn off BitLocker for the affected drive.
– After decryption, turn BitLocker back on.
For EFS:
– Right-click the encrypted file or folder.
– Choose Properties > Advanced.
– Uncheck and then re-check “Encrypt contents to secure data”, applying changes.
This can clear up issues caused by partial or failed encryption.
7. Restore User Certificates
EFS depends on user certificates. If you have a backup of your encryption certificate (a .pfx file), import it:
Open the Run dialog (Windows key + R), type certmgr.msc, and press Enter.
Right-click Personal > Certificates > All Tasks > Import.
Follow the wizard to import your backup certificate.
Without the original certificate, EFS recovery is unlikely, so regular backups are crucial.
8. Use Glary Utilities to Fix File System Errors and Clean Up
Glary Utilities can significantly streamline the repair process. Its Disk Repair and Registry Repair tools help fix file system issues that might block encryption or decryption.
Launch Glary Utilities.
Go to Advanced Tools > Disk Repair to scan for and fix file system errors.
Use Registry Repair to clean out registry issues affecting encryption operations.
Glary Utilities can also securely erase residual data, ensuring old, unencrypted versions of files don’t remain accessible.

9. Manage TPM and Secure Boot Settings
BitLocker relies on the Trusted Platform Module (TPM). If BitLocker repeatedly requests the recovery key, check your TPM settings:
Enter BIOS/UEFI during startup (usually by pressing F2, F10, DEL, or ESC).
Ensure TPM is enabled and initialized.
Check Secure Boot is enabled if your organization’s policies require it.
Changes in firmware or BIOS settings can disrupt encryption. Return them to the state present when encryption was first enabled.
10. Recover Data from Unbootable or Corrupted Drives
If a drive will not decrypt or boot, use Windows Recovery Environment (WinRE) or a live USB.
Create a Windows installation USB.
Boot from it, select Repair your computer > Troubleshoot > Command Prompt.
Try unlocking the BitLocker volume using:
manage-bde -unlock D: -RecoveryPassword YOUR-RECOVERY-KEY
If EFS-encrypted files are involved, you’ll need to copy encrypted files to another drive and later restore your certificate.
In some cases, professional data recovery services may be necessary—these often have specialized tools for handling encrypted disks.
