Adrianc 1 Posted December 1, 2020 Share Posted December 1, 2020 Hi no matter how many times I try I get the following message: An attempt was made to take ownership of the Trusted Platform Module, on workstation "FRANK-HP (98CD9D7B-33C4-11EB-8BFD-40EC99148ECA)", but the attempt failed and the following error was encountered: The TPM is not correctly configured, re-configuration is required. (0xC00B0044) I restart and press F1 to accept as i would normally but get the error above and this in the details section: The Trusted Platform Module (TPM) is unavailable, error 3 Yet it says available in the bios. Has anyone got any ideas please. Link to comment Share on other sites More sharing options...
ESET Staff JPritchard 6 Posted December 1, 2020 ESET Staff Share Posted December 1, 2020 Good afternoon, I'm sorry to hear about this issue. I suspect you are encountering a known issue with the latest version of Windows 10 2004 (OS build 19042). You can check what Windows version you are running by typing 'winver' into the Run dialog. I have attached an example: If your computer IS running Windows 10 2004 (OS build 19042), then please check to see if you are missing the UseNullDerivedOwnerAuth registry value found in: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TPM\WMI If it is missing, then you can create it manually by opening an elevated command prompt and entering the following command: reg add hklm\system\currentcontrolset\services\tpm\wmi -v UseNullDerivedOwnerAuth -t REG_DWORD -d 0x01 -f After running this command, reboot your computer before trying FDE again. This should allow the TPM to be used for encryption. Let me know how you get on. - JP Rendekovic 1 Link to comment Share on other sites More sharing options...
