When a machine is encrypted it stores the state of the BIOS/UEFI settings. If the check completes, the TPM chip will release the keys to allow BitLocker to boot the encrypted disk. Basically, these settings tell the TPM chip what to check, during the power-on cycle, that the disk is still booting inside a valid machine that hasn’t been tampered.
Pressing the F8 or F10 key during the boot processĪ lot of the above reasons are self-explanatory, but Modifying the Platform Configuration Registers (PCRs) is not always fully understood, or configured correctly. Removing, inserting, or completely depleting the charge on a smart battery (portal computer). #How do i use my bitlocker recovery key windows 10 code#
Disabling the code integrity check or enabling test signing on Windows Bootmgr. Changing the usage authorization for the storage root key of the TPM to a non-zero value. Having a BIOS or an option ROM component that is not compliant with the relevant Trusted Computing Group standards for a client computer. Upgrading the motherboard to a new one with a new TPM. Moving the BitLocker-protected drive to a different system. Hiding the TPM from the operating system. Modifying the Platform Configuration Registers (PCRs) used by the TPM validation profile. Adding or removing add-in cards (such as video or network cards), or upgrading firmware on add-in cards. Turning off, disabling, deactivating, or clearing the TPM. Changes to NTFS partition table on the disk including: Creating, Deleting, Resizing primary partition. Docking or undocking a portal computer if the computer was (respectively) undocked or docked when BitLocker was turned on. Using a BIOS hot key during the boot process to change the boot order to something other than the hard drive. Failing to boot from a network drive before booting from the hard drive. Changes to the boot manager (bootmgr) on the disk. Changes to the master boot record (MBR) on the disk. Upgrading critical early startup components such as BIOS upgrades. Changing the BIOS boot order to boot another drive ahead of the hard drive (such as giving a CD or DVD drive boot sequence priority). Turning off BIOS support for reading USB devices in the pre-boot environment when using USB-based keys. Losing the USB flash drive containing the startup key. Using a keyboard with a different layout that doesn’t enter the PIN correctly, or one that doesn’t map as assumed by the pre-boot environment. Entering incorrect PIN too many times (activating the anti-hammering logic of the TPM). Both options require user interaction and can lead to lockouts in the event of a forgotten PIN, or lost USB.īitLocker Recovery Mode can occur for many reasons, including: 
Microsoft recommends using the TPM with a BitLocker PIN or startup key loaded on a USB to uplift security. This method does not require the user to do anything, and it is the least secure.
It automatically decrypts hard drives on startup, without requiring the use of a PIN code, USB, or other form of authentication. The most common authentication method is using the Trusted Protection Module (TPM), a microchip that is built into some laptops and desktops.

BitLocker has been a part of the Windows operating system since 2007 but Microsoft greatly enhanced BitLocker in Windows 10 version 1511, by introducing new encryption algorithms and making it possible to configure group policy settings separately for fixed data drives, removable data drives, and operating system drives.īitLocker authentication methods can trigger user lockouts. BitLocker Drive Encryption, which is commonly referred to simply as BitLocker, allows Windows users to encrypt hard drives in an effort to keep data secure. Let’s start with an overview of BitLocker. This blog will look at the root causes of BitLocker Recovery Mode, and how your organization can mitigate the issue with self-service key recovery.
