Thanks. It's nice to see a reason for it and that others are seeing it, too. Yes, the data are mostly generalized auto fill. I'd prefer to live with something then delete it from the registry and find my new system crashing.
I just built a new system and upgraded from Windows 8.1 to Windows 11 22H2 Pro. I tweak a lot and modify the registry carefully.
I found a whole lot of keys that are totally in or partially in Chinese characters. Some of the values are in Chinese, too.
Do I need to do a deep dive and delete...
