Hi there! As for your first question, I know I had trouble with that one until I used the update to move from 21h2 to 22h2, and then that security update installed successfully… What version of Tiny10 did you install from archive.org?
If Tiny10 is working better for you, then definitely go with Tiny11!
If it runs successfully, then going into This PC properties after you run the command should show 22h2 in the version name…
