It's a new requirement from the CIA. Having a unique MAC address is no longer sufficient to track you down. A TPM chip serves you better. Fortunately Windows is soon to expire. Who still wants to use Windows with HarmonyOS for PCs around the corner?
I replaced my windows 11 hard drive with a new ssd drive. I put the old hhd drive on my old pc that couldn't update. It works So far.
