Cause

This issue occurs because Windows automatically starts encrypting drives by using BitLocker on Windows 8.1-based computers that support InstantGo (connected standby).

↑ Back to the top

Resolution

To resolve this issue, in Command Prompt as an administrator, run the following command:

manage-bde -off c:

Notes
  • The command may take some time to fully decrypt the drive. You can run the manage-bde -status command to monitor progress. 
  • When full decryption is complete, you can run Sysprep.exe again.
  • To prevent this issue during the initial install of Windows, set the PreventDeviceEncryption value to True in the unattend.xml file during the out-of-body experience (OOBE) phase to build the reference image. For more information, see the PreventDeviceEncryption.

More Information

After you set the value in the unattend.xml file, the following registry subkey and registry entry is created:
Subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BitLocker
Name: PreventDeviceEncryption
Type: REG_DWORD
Data: 0x00000001
