Hi Everyone, I have installed windows 10 enterprise. This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question 0. Report abuse. Details required :. Cancel Submit. Hi Sara. If Bitlocker is enabled on your hard drive this may have been done at the factory, which the manufacturer's Support should tell you and provide what you need to know.
Due to number of similar cases with files lost I would not use Bitlocker. Instead I would periodically drag my User folders to external USB which I keep unplugged to protect against ransomware.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This article for IT professionals describes the function, location, and effect of each Group Policy setting that is used to manage BitLocker Drive Encryption. To control the drive encryption tasks the user can perform from the Windows Control Panel or to modify other configuration options, you can use Group Policy administrative templates or local computer policy settings.
How you configure these policy settings depends on how you implement BitLocker and what level of user interaction will be allowed. If a computer isn't compliant with existing Group Policy settings, BitLocker may not be turned on or modified until the computer is in a compliant state.
When a drive is out of compliance with Group Policy settings for example, if a Group Policy setting was changed after the initial BitLocker deployment in your organization, and then the setting was applied to previously encrypted drives , no change can be made to the BitLocker configuration of that drive except a change that will bring it into compliance.
If multiple changes are necessary to bring the drive into compliance, you must suspend BitLocker protection, make the necessary changes, and then resume protection. This situation could occur, for example, if a removable drive is initially configured to be unlocked with a password and then Group Policy settings are changed to disallow passwords and require smart cards.
In this situation, you need to suspend BitLocker protection by using the Manage-bde command-line tool, delete the password unlock method, and add the smart card method. After this is complete, BitLocker is compliant with the Group Policy setting and BitLocker protection on the drive can be resumed. The following sections provide a comprehensive list of BitLocker group policy settings that are organized by usage.
BitLocker group policy settings include settings for specific drive types operating system drives, fixed data drives, and removable data drives and settings that are applied to all drives. The following policy settings can be used to determine how a BitLocker-protected drive can be unlocked.
The following policy settings are used to control how users can access drives and how they can use BitLocker on their computers. The following policy settings determine the encryption methods and encryption types that are used with BitLocker. The following policy settings define the recovery methods that can be used to restore access to a BitLocker-protected drive if an authentication method fails or is unable to be used.
The preboot authentication option Require startup PIN with TPM of the Require additional authentication at startup policy is often enabled to help ensure security for older devices that don't support Modern Standby. But visually impaired users have no audible way to know when to enter a PIN. This setting enables an exception to the PIN-required policy on secure hardware.
This policy controls a portion of the behavior of the Network Unlock feature in BitLocker. This policy is required to enable BitLocker Network Unlock on a network because it allows clients running BitLocker to create the necessary network key protector during encryption. This policy is used with the BitLocker Drive Encryption Network Unlock Certificate security policy located in the Public Key Policies folder of Local Computer Policy to allow systems that are connected to a trusted network to properly utilize the Network Unlock feature.
To use a network key protector to unlock the computer, the computer and the server that hosts BitLocker Drive Encryption Network Unlock must be provisioned with a Network Unlock certificate. The Network Unlock certificate is used to create a network key protector and to protect the information exchange with the server to unlock the computer. This unlock method uses the TPM on the computer, so computers that don't have a TPM can't create network key protectors to automatically unlock by using Network Unlock.
For reliability and security, computers should also have a TPM startup PIN that can be used when the computer is disconnected from the wired network or can't connect to the domain controller at startup. This policy setting is used to control which unlock options are available for operating system drives. Only one of the additional authentication options can be required at startup; otherwise, a policy error occurs. In this mode, a password or USB drive is required for startup.
The USB drive stores the startup key that is used to encrypt the drive. When the USB drive is inserted, the startup key is authenticated and the operating system drive is accessible. On a computer with a compatible TPM, additional authentication methods can be used at startup to improve protection for encrypted data.
When the computer starts, it can use:. Enhanced startup PINs permit the use of characters including uppercase and lowercase letters, symbols, numbers, and spaces. This policy setting is applied when you turn on BitLocker. Not all computers support enhanced PIN characters in the preboot environment. It's strongly recommended that users perform a system check during the BitLocker setup to verify that enhanced PIN characters can be used.
The startup PIN must have a minimum length of four digits and can have a maximum length of 20 digits. Windows Hello has its own PIN for logon, length of which can be 4 to characters. The TPM can be configured to use Dictionary Attack Prevention parameters lockout threshold and lockout duration to control how many failed authorizations attempts are allowed before the TPM is locked out, and how much time must elapse before another attempt can be made.
The Dictionary Attack Prevention Parameters provide a way to balance security needs with usability. A TPM 2. This totals a maximum of about guesses per year. Increasing the PIN length requires a greater number of guesses for an attacker. In that case, the lockout duration between each guess can be shortened to allow legitimate users to retry a failed attempt sooner, while maintaining a similar level of protection.
To help organizations with the transition, beginning with Windows 10, version and Windows 10, version with the October , or Windows 11 cumulative update installed, the BitLocker PIN length is six characters by default, but it can be reduced to four characters. This policy setting is only enforced when BitLocker or device encryption is enabled. As explained in the Microsoft Security Guidance blog , in some cases when this setting is enabled, internal, PCI-based peripherals can fail, including wireless network drivers and input and audio peripherals.
This problem is fixed in the April quality update. This policy setting allows you to configure whether standard users are allowed to change the PIN or password that is used to protect the operating system drive. This policy controls how non-TPM based systems utilize the password protector.
Used with the Password must meet complexity requirements policy, this policy allows administrators to require password length and complexity for using the password protector. By default, passwords must be eight characters in length.
Complexity configuration options determine how important domain connectivity is for the client. For the strongest password security, administrators should choose Require password complexity because it requires domain connectivity, and it requires that the BitLocker password meets the same password complexity requirements as domain sign-in passwords. When enabled Users can configure a password that meets the requirements you define.
To enforce complexity requirements for the password, select Require complexity. When disabled or not configured The default length constraint of eight characters will apply to operating system drive passwords and no complexity checks will occur. If non-TPM protectors are allowed on operating system drives, you can provision a password, enforce complexity requirements on the password, and configure a minimum length for the password. These settings are enforced when turning on BitLocker, not when unlocking a volume.
BitLocker allows unlocking a drive with any of the protectors that are available on the drive. When set to Require complexity , a connection to a domain controller is necessary when BitLocker is enabled to validate the complexity the password. When set to Allow complexity , a connection to a domain controller is attempted to validate that the complexity adheres to the rules set by the policy.
If no domain controllers are found, the password will be accepted regardless of actual password complexity, and the drive will be encrypted by using that password as a protector. When set to Do not allow complexity , there is no password complexity validation. Passwords must be at least eight characters. To configure a greater minimum length for the password, enter the desired number of characters in the Minimum password length box.
When this policy setting is enabled, you can set the option Configure password complexity for operating system drives to:. This policy setting is used to control what unlock options are available for computers running Windows Server or Windows Vista. On a computer with a compatible TPM, two authentication methods can be used at startup to provide added protection for encrypted data. When the computer starts, it can prompt users to insert a USB drive that contains a startup key.
It can also prompt users to enter a startup PIN with a length between 6 and 20 digits. These options are mutually exclusive. If you require the startup key, you must not allow the startup PIN.
If you require the startup PIN, you must not allow the startup key. Otherwise, a policy error will occur. To hide the advanced page on a TPM-enabled computer or device, set these options to Do not allow for the startup key and for the startup PIN. This policy setting is used to require, allow, or deny the use of smart cards with fixed data drives. These settings are enforced when turning on BitLocker, not when unlocking a drive. BitLocker allows unlocking a drive by using any of the protectors that are available on the drive.
This policy setting is used to require, allow, or deny the use of passwords with fixed data drives. When set to Require complexity , a connection to a domain controller is necessary to validate the complexity of the password when BitLocker is enabled. However, if no domain controllers are found, the password is accepted regardless of the actual password complexity, and the drive is encrypted by using that password as a protector.
When set to Do not allow complexity , no password complexity validation is performed. This policy setting is configured on a per-computer basis. This means that it applies to local user accounts and domain user accounts. Because the password filter that's used to validate password complexity is located on the domain controllers, local user accounts can't access the password filter because they're not authenticated for domain access.
When this policy setting is enabled, if you sign in with a local user account, and you attempt to encrypt a drive or change a password on an existing BitLocker-protected drive, an "Access denied" error message is displayed. In this situation, the password key protector can't be added to the drive. Enabling this policy setting requires that connectivity to a domain be established before adding a password key protector to a BitLocker-protected drive.
Users who work remotely and have periods of time in which they can't connect to the domain should be made aware of this requirement so that they can schedule a time when they will be connected to the domain to turn on BitLocker or to change a password on a BitLocker-protected data drive.
Passwords can't be used if FIPS compliance is enabled. This policy setting is used to require, allow, or deny the use of smart cards with removable data drives. This policy setting is used to require, allow, or deny the use of passwords with removable data drives. If you choose to allow the use of a password, you can require a password to be used, enforce complexity requirements, and configure a minimum length. To configure a greater minimum length for the password, enter the wanted number of characters in the Minimum password length box.
When set to Require complexity , a connection to a domain controller is necessary when BitLocker is enabled to validate the complexity of the password. When set to Allow complexity , a connection to a domain controller is be attempted to validate that the complexity adheres to the rules set by the policy. However, if no domain controllers are found, the password is still be accepted regardless of actual password complexity and the drive is encrypted by using that password as a protector.
