VirtualBox fixes Windows black screen, TPM save, nested virtualization, BIOS bugs

windows 11 tpm

Close to the general availability (GA) of Windows 11, Oracle started working on TPM (Trusted Platform Module) passthrough for Windows 11 support. And almost a year later, the hypervisor gained support for Windows 11 hosts. TPM 2.0 and Secure Boot support soon arrived after this, though as recently as July of 2023, TPM-related bugs like crashes have been addressed.

The latest maintenance release today also has fixes related to TPM saved states. Aside from that, a black screen issue has also been fixed. There are other fixes in the release as well. The full changelog is given below:
