Enabling and Disabling BitLocker in Windows 7, Windows 8, Windows 10 and Windows 11

Windows BitLocker has become a solution for users to secure their data. The following is how to enable and disable BitLocker using the standard methods.

This article does not discuss the utilization of a USB as a TPM replacement and does not discuss Group Policy changes for advanced features. Domain level Group Policy changes and network-managed BitLocker setups are Best Effort and are out of the scope of support. Supported configurations are limited to single computers and locally managed BitLocker setups.

NOTE: Systems with Skylake chipsets need a specific setup in order for BitLocker to work correctly. If a Skylake computer is prompting for the recovery key even with the following settings, ENSURE that the BIOS is up to date.
  • All Operating Systems that are configured in Legacy Boot Mode must use TPM 1.2. It is recommended that the BIOS be updated to the latest revision.
  • All Operating Systems that are configured in UEFI Boot Mode can use either TPM 1.2, or TPM 2.0. It is recommended that the BIOS be updated to the latest revision.
  • If a Windows 7 computer is configured for UEFI Boot Mode, this patch must be applied in order to use TPM 2.0: Microsoft TPM 2.0 Patch This hyperlink is taking you to a website outside of Dell Technologies.
  • Exceptions to this are the Latitude 5175 and Latitude 7275, both of which only have TPM 2.0 and cannot downgrade to 1.2.
NOTE: For full, up-to-date requirements, see Microsoft's BitLocker requirements This hyperlink is taking you to a website outside of Dell Technologies.

1. Enabling the TPM

NOTE: Ensure that the TPM is Activated or Enabled after switching it on, if the option is present. Switching the TPM on does not automatically enable it to communicate with the operating system. Enabling the TPM is necessary for the operating system to take ownership of the TPM chip to store encryption keys.
  1. Turn the computer on.
  2. As the computer performs POST, press the hotkey (usually F2, or Delete) to enter the BIOS.
  3. Once in the BIOS, locate the section that configures Security.
  4. In the Security section, locate the TPM option.
  5. Select the TPM 2.0 or 1.2 section on the left.

    Select the TPM 2.0 or 1.2
