what is happening here

See my comment above. May be of help.

CTT Windows Utility

Uninstalled it months ago and haven’t seen it since. You can also set updates to only install security updates 4 days after release and feature updates after 2 years of release.

This and StartAllBack are my answers when I hear “just install Linux and ditch windows”

CTT Windoes Utility -> Tweaks -> Remove Microsoft Edge

Removed edge when I got my new computer about a year ago and haven’t seen it since.

You are right, it’s part of the subtitles. Not sure why I did not think of that.

Also thanks for recommending mkvtool, never heard of it until now which is great because when I play LOTR from a flash drive on my TV, it defaults to Italian language.
