Re: At Dave K, re: LTSB.
This line of reasoning (from a legal point of view) is like carjacking a 2019 Mercedes-Benz S560 and driving away, simply because I have paid for a same-model-year-but-ten-times-cheaper Mercedes B-Class EV. It's not my fault that Mercedes built a crappy, generic four-door wagon with a limited drive range (compared to a regular car).
However, your suggestion of renewing the trial is actually sound. After 90 days * 3 renewals (M$ calls them "rearms") = 270 days (nine months), Windows would need a reinstallation anyhow (because of the bloat that accumulated in the internim).
