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 11 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...
