If the USB flash drive that contains your startup key is lost or stolen, you also lose access to your recovery key. In addition, inserting this key would cause your computer to automatically boot from the recovery key even if TPM-measured files have changed, which circumvents the TPM's system integrity check. - -### Can I save the startup key on multiple USB flash drives? - -Yes, you can save a computer's startup key on multiple USB flash drives. Right-clicking a BitLocker-protected drive and selecting **Manage BitLocker** will provide you the options to duplicate the recovery keys as needed. - -### Can I save multiple (different) startup keys on the same USB flash drive? - -Yes, you can save BitLocker startup keys for different computers on the same USB flash drive. - -### Can I generate multiple (different) startup keys for the same computer? - -You can generate different startup keys for the same computer through scripting. However, for computers that have a TPM, creating different startup keys prevents BitLocker from using the TPM's system integrity check. - -### Can I generate multiple PIN combinations? - -You cannot generate multiple PIN combinations. - -### What encryption keys are used in BitLocker? How do they work together? - -Raw data is encrypted with the full volume encryption key, which is then encrypted with the volume master key. The volume master key is in turn encrypted by one of several possible methods depending on your authentication (that is, key protectors or TPM) and recovery scenarios. - -### Where are the encryption keys stored? - -The full volume encryption key is encrypted by the volume master key and stored in the encrypted drive. The volume master key is encrypted by the appropriate key protector and stored in the encrypted drive. If BitLocker has been suspended, the clear key that is used to encrypt the volume master key is also stored in the encrypted drive, along with the encrypted volume master key. - -This storage process ensures that the volume master key is never stored unencrypted and is protected unless you disable BitLocker. The keys are also saved to two additional locations on the drive for redundancy. The keys can be read and processed by the boot manager. - -### Why do I have to use the function keys to enter the PIN or the 48-character recovery password? - -The F1 through F10 keys are universally mapped scan codes available in the pre-boot environment on all computers and in all languages. The numeric keys 0 through 9 are not usable in the pre-boot environment on all keyboards. - -When using an enhanced PIN, users should run the optional system check during the BitLocker setup process to ensure that the PIN can be entered correctly in the pre-boot environment. - -### How does BitLocker help prevent an attacker from discovering the PIN that unlocks my operating system drive? - -It is possible that a personal identification number (PIN) can be discovered by an attacker performing a brute force attack. A brute force attack occurs when an attacker uses an automated tool to try different PIN combinations until the correct one is discovered. For BitLocker-protected computers, this type of attack, also known as a dictionary attack, requires that the attacker have physical access to the computer. - -The TPM has the built-in ability to detect and react to these types of attacks. Because different manufacturers' TPMs may support different PIN and attack mitigations, contact your TPM's manufacturer to determine how your computer's TPM mitigates PIN brute force attacks. -After you have determined your TPM's manufacturer, contact the manufacturer to gather the TPM's vendor-specific information. Most manufacturers use the PIN authentication failure count to exponentially increase lockout time to the PIN interface. However, each manufacturer has different policies regarding when and how the failure counter is decreased or reset. - -### How can I determine the manufacturer of my TPM? - -You can determine your TPM manufacturer in the TPM MMC console (tpm.msc) under the **TPM Manufacturer Information** heading. - -### How can I evaluate a TPM's dictionary attack mitigation mechanism? - -The following questions can assist you when asking a TPM manufacturer about the design of a dictionary attack mitigation mechanism: - -- How many failed authorization attempts can occur before lockout? -- What is the algorithm for determining the duration of a lockout based on the number of failed attempts and any other relevant parameters? -- What actions can cause the failure count and lockout duration to be decreased or reset? - -### Can PIN length and complexity be managed with Group Policy? - -Yes and No. You can configure the minimum personal identification number (PIN) length by using the **Configure minimum PIN length for startup** Group Policy setting and allow the use of alphanumeric PINs by enabling the **Allow enhanced PINs for startup** Group Policy setting. However, you cannot require PIN complexity by Group Policy. - -For more info, see [BitLocker Group Policy settings](bitlocker-group-policy-settings.md). - ## BitLocker To Go BitLocker To Go is BitLocker Drive Encryption on removable data drives.

That is still the most secure way to encrypt a drive, especially if a drive has previously contained confidential data that has since been moved or deleted. In that case, traces of the confidential data could remain on portions of the drive marked as unused. But why encrypt a new drive when you can simply encrypt the data as it is being written? To reduce encryption time, BitLocker in Windows 10 lets users choose to encrypt just their data. Depending on the amount of data on the drive, this option can reduce encryption time by more than 99 percent. Exercise caution when encrypting only used space on an existing volume on which confidential data may have already been stored in an unencrypted state, however, because those sectors can be recovered through disk-recovery tools until they are overwritten by new encrypted data. In contrast, encrypting only used space on a brand-new volume can significantly decrease deployment time without the security risk because all new data will be encrypted as it is written to the disk. diff --git a/windows/security/information-protection/bitlocker/bitlocker-frequently-asked-questions.md b/windows/security/information-protection/bitlocker/bitlocker-frequently-asked-questions.md index 0f59f82df1..f67a251bc7 100644 --- a/windows/security/information-protection/bitlocker/bitlocker-frequently-asked-questions.md +++ b/windows/security/information-protection/bitlocker/bitlocker-frequently-asked-questions.md @@ -32,42 +32,6 @@ BitLocker is a data protection feature that encrypts the hard drives on your com -## BitLocker To Go - -BitLocker To Go is BitLocker Drive Encryption on removable data drives.

However, the debugger should be turned on before enabling BitLocker. Turning on the debugger ensures that the correct measurements are calculated when sealing to the TPM, allowing the computer to start properly. If you need to turn debugging on or off when using BitLocker, be sure to suspend BitLocker first to avoid putting your computer into recovery mode. - -### How does BitLocker handle memory dumps? - -BitLocker has a storage driver stack that ensures memory dumps are encrypted when BitLocker is enabled. - -### Can BitLocker support smart cards for pre-boot authentication? - -BitLocker does not support smart cards for pre-boot authentication. There is no single industry standard for smart card support in the firmware, and most computers either do not implement firmware support for smart cards, or only support specific smart cards and readers. This lack of standardization makes supporting them very difficult. - -### Can I use a non-Microsoft TPM driver? - -Microsoft does not support non-Microsoft TPM drivers and strongly recommends against using them with BitLocker. Attempting to use a non-Microsoft TPM driver with BitLocker may cause BitLocker to report that a TPM is not present on the computer and not allow the TPM to be used with BitLocker. - -### Can other tools that manage or modify the master boot record work with BitLocker? - -We do not recommend modifying the master boot record on computers whose operating system drives are BitLocker-protected for a number of security, reliability, and product support reasons. Changes to the master boot record (MBR) could change the security environment and prevent the computer from starting normally, as well as complicate any efforts to recover from a corrupted MBR.

First, check your BIOS or UEFI firmware and boot settings to ensure that the use of USB drives is enabled. If it is not enabled, enable the use of USB drives in the BIOS or UEFI firmware and boot settings and then try to read the recovery key from the USB flash drive again. If it still cannot be read, you will have to mount the hard drive as a data drive on another computer so that there is an operating system to attempt to read the recovery key from the USB flash drive. If the USB flash drive has been corrupted or damaged, you may need to supply a recovery password or use the recovery information that was backed up to AD DS. Also, if you are using the recovery key in the pre-boot environment, ensure that the drive is formatted by using the NTFS, FAT16, or FAT32 file system. - -### Why am I unable to save my recovery key to my USB flash drive? - -The **Save to USB** option is not shown by default for removable drives. If the option is unavailable, it means that a system administrator has disallowed the use of recovery keys. - -### Why am I unable to automatically unlock my drive? - -Automatic unlocking for fixed data drives requires that the operating system drive also be protected by BitLocker. If you are using a computer that does not have a BitLocker-protected operating system drive, the drive cannot be automatically unlocked. For removable data drives, you can add automatic unlocking by right-clicking the drive in Windows Explorer and clicking **Manage BitLocker**. You will still be able to use the password or smart card credentials you supplied when you turned on BitLocker to unlock the removable drive on other computers. - -### Can I use BitLocker in Safe Mode? - -Limited BitLocker functionality is available in Safe Mode. BitLocker-protected drives can be unlocked and decrypted by using the **BitLocker Drive Encryption** Control Panel item. Right-clicking to access BitLocker options from Windows Explorer is not available in Safe Mode. - -### How do I "lock" a data drive? - -Both fixed and removable data drives can be locked by using the Manage-bde command-line tool and the –lock command. - ->**Note:**  Ensure all data is saved to the drive before locking it. Once locked, the drive will become inaccessible. -  -The syntax of this command is: - -`manage-bde -lock` - -Outside of using this command, data drives will be locked on shutdown and restart of the operating system. A removable data drive will also be locked automatically when the drive is removed from the computer. - -### Can I use BitLocker with the Volume Shadow Copy Service? - -Yes. However, shadow copies made prior to enabling BitLocker will be automatically deleted when BitLocker is enabled on software-encrypted drives. If you are using a hardware encrypted drive, the shadow copies are retained. - -### Does BitLocker support virtual hard disks (VHDs)? - -BitLocker is not supported on bootable VHDs, but BitLocker is supported on data volume VHDs, such as those used by clusters, if you are running Windows 10, Windows 8.1, Windows 8, Windows Server 2012, or Windows Server 2012 R2. - -### Can I use BitLocker with virtual machines (VMs)? - -Yes.

For example, many manufacturers configure Internet Explorer using Unattend settings. If a user purchases a laptop, and then signs up for Internet service, their Internet Service Provider (ISP) might provide a version of Internet Explorer that has been branded (for example, with a custom homepage for that ISP) using Internet Explorer Customization Wizard 11.

What tools can I use to manage Windows Updates and Microsoft Updates in my company?** +A. We encourage anyone who wants full control over their company’s deployment of Windows Updates and Microsoft Updates, to use [Windows Server Update Services (WSUS)](https://docs.microsoft.com/windows-server/administration/windows-server-update-services/get-started/windows-server-update-services-wsus), a free tool for users of Windows Server. You can also use the more advanced configuration management tool, [System Center 2012 Configuration Manager](https://technet.microsoft.com/library/gg682041.aspx). + +**Q. How long does the blocker mechanism work?** +A. The Internet Explorer 11 Blocker Toolkit uses a registry key value to permanently turn off the automatic delivery of Internet Explorer 11. This behavior lasts as long as the registry key value isn’t removed or changed. + +**Q. Why should I use the Internet Explorer 11 Blocker Toolkit to stop delivery of Internet Explorer 11? Why can’t I just disable all of utomatic Updates?** +A. Automatic Updates provide you with ongoing critical security and reliability updates. Turning this feature off can leave your computers more vulnerable. Instead, we suggest that you use an update management solution, such as WSUS, to fully control your environment while leaving this feature running, managing how and when the updates get to your user’s computers. + +The Internet Explorer 11 Blocker Toolkit safely allows Internet Explorer 11 to download and install in companies that can’t use WSUS, Configuration Manager, or other update management solution. + +**Q. Why don’t we just block URL access to Windows Update or Microsoft Update?** +A. Blocking the Windows Update or Microsoft Update URLs also stops delivery of critical security and reliability updates for all of the supported versions of the Windows operating system; leaving your computers more vulnerable. + +### How the Internet Explorer 11 Blocker Toolkit works + +**Q. How should I test the Internet Explorer 11 Blocker Toolkit in my company?** +A. Because the toolkit only sets a registry key to turn on and off the delivery of Internet Explorer 11, there should be no additional impact or side effects to your environment. No additional testing should be necessary. + +**Q. What’s the registry key used to block delivery of Internet Explorer 11?** +A. HKLM\\SOFTWARE\\Microsoft\\Internet Explorer\\Setup\\11.0 + +**Q. What’s the registry key name and values?** +The registry key name is **DoNotAllowIE11**, where: + +- A value of **1** turns off the automatic delivery of Internet Explorer 11 + using Automatic Updates and turns off the Express install option. + +- Not providing a registry key, or using a value of anything other than **1**, + lets the user install Internet Explorer 11 through Automatic Updates or a + manual update. + +**Q. Does the Internet Explorer 11 Blocker Toolkit stop users from manually installing Internet Explorer 11?** +A. No. The Internet Explorer 11 Blocker Toolkit only stops computers from automatically installing Internet Explorer 11 through Automatic Updates. Users can still download and install Internet Explorer 11 from the Microsoft Download Center or from external media. + +**Q. Does the Internet Explorer 11 Blocker Toolkit stop users from automatically upgrading to Internet Explorer 11?** +A. Yes. The Internet Explorer 11 Blocker Toolkit also prevents Automatic Updates from automatically upgrading a computer from Internet Explorer 8, Internet Explorer 9, or Internet Explorer 10 to Internet Explorer 11. + +**Q. How does the provided script work?** +A. The script accepts one of two command line options: + +- **Block:** Creates the registry key that stops Internet Explorer 11 from installing through Automatic Updates. + +- **Unblock:** Removes the registry key that stops Internet Explorer 11 from installing through Automatic Updates. + +**Q. What’s the ADM template file used for?** +A. The Administrative Template (.adm file) lets you import the new Group Policy environment and use Group Policy Objects to centrally manage all of the computers in your company. + +**Q. Is the tool localized?** +A. No. The tool isn’t localized, it’s only available in English (en-us). However, it does work, without any modifications, on any language edition of the supported operating systems. + +### Internet Explorer 11 Blocker Toolkit and other update services + +**Q. Does the Internet Explorer 11 blocking mechanism also block delivery of Internet Explorer 11 through update management solutions, like SUS?** +A. No. You can still deploy Internet Explorer 11 using one of the upgrade management solutions, even if the blocking mechanism is activated. The Internet Explorer 11 Blocker Toolkit is only intended for companies that don’t use upgrade management solutions. + +**Q. If WSUS is set to 'auto-approve' Update Rollup packages (this is not the default configuration), how do I stop Internet Explorer 11 from automatically installing throughout my company?** +A. You only need to change your settings if: + +- You use WSUS to manage updates and allow auto-approvals for Update Rollup installation. + + -and- + +- You have computers running either Windows 7 SP1 or Windows Server 2008 R2 (SP1) with Internet Explorer 8, Internet Explorer 9, or Internet Explorer 10 installed. + + -and- + +- You don’t want to upgrade your older versions of Internet Explorer to Internet Explorer 11 right now. + +If these scenarios apply to your company, see [Internet Explorer 11 delivery through automatic updates](https://technet.microsoft.com/microsoft-edge/dn449235) for more information on how to prevent automatic installation.
