My cpu is also to old (5960x) but I get automatic updates. There are/were multiple methods to getting windows 11 to work on invalid hardware, maybe some don’t work with auto updates.

You can get windows 11 working on non tpm 2.0 systems. It’s a soft requirement that Microsoft enforces with the stock installer but can be bypasses.

I had these on my hike to Lake Serene, absolutely amazing after a long hike.
