So Windows 10 is now end of life, and my desktop PC I use for gaming, Fusion, and Cricut software is not compatible with Windows 11. I found the reason was my motherboard does not have a TPM module required for Windows 11. TPM stands for Trusted Platform Module, and is a hardware based security feature. It allows for keys to be stored in a dedicated chip, allowing for the hardware to be verified at boot time, and for features like BitLocker disk encryption to be used.
