Check if TPM 2.0 is present for Windows 11.(See also the steps to enable these two security features on VMware Workstation and Hyper-V to run the new OS on a virtual machine.) This guide will teach you the steps to check and enable TPM 2.0 and Secure Boot to install Windows 11. On the other hand, Secure Boot is a module that ensures that the device boots only using the software that the manufacturer trusts. TPM is a piece of hardware, usually (but not always) integrated into the motherboard, which offers a secure environment to store and protect the encryption keys when encrypting the hard drive using features like BitLocker. According to Microsoft, TPM 2.0 and Secure Boot are needed to provide a better security environment and prevent (or at least minimize) sophisticated attacks, common malware, ransomware, and other threats. On Windows 11, one of the most significant changes is the requirement for Trusted Platform Module (TPM) version 2.0 and Secure Boot. The official support page of KB5012170 though does not list Windows 11 22H2 at the moment.If you plan to upgrade to Windows 11, you must first check and enable TPM 2.0 and Secure Boot in the BIOS (UEFI) of your computer’s motherboard (from Asus, Dell, MSI, GigaByte, etc.) as part of the preparation. Interestingly, while this update was initially released for Windows 11 21H2 and previous Windows 10 versions, among others, it looks like Microsoft is now beginning to push it on Windows 11 22H2 as well. Microsoft's health dashboard still lists these bugs as "investigating" and "confirmed" implying there is more to the story here.
This time, users reported that after installing the update, their systems were forced into BitLocker recovery mode, forcing the Redmond firm to provide steps to workaround the bug. Well apparently, it was just the start, as a week later, Microsoft also acknowledged another issue relating to the KB5012170 update. However, the update was found to be causing issues as it was failing to install with error code 0x800f0922, and as a workaround, Microsoft suggested updating the UEFI. Likewise, the one in August patched several flaws, including one for a critical Secure Boot DBX GRUB vulnerability (KB5012170). These aren't feature-rich, but instead fix security vulnerabilities in Windows.
Microsoft releases security updates on Patch Tuesday, which is every second Tuesday of the month.
