Setting up a fresh Windows 11 Pro installation on an MSI B450 Gaming Plus Max running the newest BIOS is straightforward. The system features a Ryzen 5 3600 processor. During startup, the TPM appears active in my security preferences, and I can open the tpm.msc window. Although Windows doesn’t show any warnings, after some time the TPM details vanish from the settings, leaving only a message: “I initially thought my hardware might not support Windows 11.” I recall that a Windows 10 health check confirmed compatibility before the clean install using a USB drive. It seems Windows 11 should provide feedback if issues arise. Is there any hardware or software issue at play?

You’ve likely removed TPM keys from the BIOS. You must re-register it: Launch PowerShell with admin privileges, then run the commands: C:\> $tpm = gwmi -n root\cimv2\security\microsofttpm win32_tpm C:\> $tpm.SetPhysicalPresenceRequest(6). After completion, restart your machine.
