Wordpad MSWord and Libreoffice [View all]

I got a new laptop recently, and it has Windows Accessories>Wordpad, and MS Office. I didn't want to buy office, don't use it enough to justify. So I saved rtf docs in Wordpad. But for some reason, when I open them, they open in MS Word and I get all these messages that I need to buy it.

I looked for a solution, but all of the Google hits that come up are about Word documents opening in Wordpad, opposite of what is happening on my laptop.

I said the heck with it and downloaded LibreOffice, a free word processor that I have on my tablet. it is a good solution, even if it didn't help me figure out why my laptop saves the way it does. The rtf documents I have automatically turned into LibreOffice, so won't have to open MS Office Word at all.
