This means that the line to search for and the value differ in each language. The command line program Manage-BDE is unfortunately localized. This can be done with some PowerShell and the good old Manage-BDE command. Preferably without having to get to all the computers. Then there is no way around it.īut if I can now live with the settings, I just want to make sure that the correct information has been backed up. I have to do this in any case, if I want to do for example 256-bit encryption and I have run into the automatic encryption. What now? Option one is to decrypt and re-encrypt with the correct settings. How can I use PowerShell to back up the keys to Active Directory? An entry in the registry is the other option: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BitLocker Value: PreventDeviceEncryption equal to True (1).Include in the MDT task sequence: For this the entry "BDEDisablePreProvioning" must be set in the CustomSettings.ini.These are particularly interesting for companies: Prevent BitLocker automatic device encryption

More on the topic: BitLocker drive encryption in Windows 10 for OEMs | Microsoft Docs. It can also happen that the encryption will strike if the devices are joined via policies of a Hybrit-AD, that is adding to an Azure AD in addition to the local Active Directory domain. The device then stores the information in Azure AD and in the Microsoft account with which it was logged in. This also applies to autopilot devices! Therefore, the encryption will only take place according to standard settings. Since the device is not yet in the domain in the OOBE, no policies apply. If the hardware supports the function, which actually all current devices do, and you log into the Out-of-the-Box Experience (OOBE) with a Microsoft account or an Azure AD user, BitLocker already encrypts at that moment. This function is called "BitLocker automatic device encryption" and is a security function from Microsoft's point of view. Joking aside, this is not due to the OEM's this is a requirement from Microsoft that the manufacturer may place the nice "Windows 10" sticker on it. Yes, the evil manufacturer did it, and only because we are so mean. encrypted my machine and I can't restore it".
BitLocker encryption by the manufacturer / OEMĪs some know, I work at Dell Technologies, so I often read on the TechNet forums "Dell/Lenovo/HP/. I would especially like to talk about the "Evil" encryption by OEM here, as this topic often concerns me in this context. The reasons vary, but the most common three are: One look into the Active Directory and there is no information there! Why the BitLocker recovery keys cannot be found in Active Directory This is the theoretical view of most environments using BitLocker without management solutions like Microsoft BitLocker Administration and Monitoring (MBAM).
"No problem, the GPO says they are stored in AD".
A typical problem, a computer encrypted with BitLocker goes on failure and asks for the recovery key.
