This article describes an issue in which Trusted Platform Module (TPM) lockout occurs unexpectedly in Windows 8.1, Windows RT 8.1, or Windows Server 2012 R2. An update is available to fix this issue. Before you install this update, see the Prerequisites section.Note This update is re-released on October 13, 2015, with a smaller boot loader file bootmgfw.efi.
Symptoms
When this issue occurs, applications that depend on TPM won't function until you reset the TPM lockout. Note You can enter a 48-digit BitLocker recovery key to continue using the computer after TPM is locked out.
Cause
When the start command is received without a prior shutdown command, the lockout count increments. This causes the TPM lockout to occur if you turn on the device accidentally and repeatedly.
