Sure, WordPad wasn’t a great editor - but in the grand scheme of poor quality software, it really wasn’t that bad. Even in the grand scheme of the wider Windows operating system it was far from being the most egregious mis-feature. Anything that requires me to waste time uninstalling it / hiding it is going to come further up my personal list of Microsoft errors - not least the in-your-face advertising that Windows insists on throwing at users or the Xbox Game Centre (or any gaming stuff since I’m not a gamer).
I’m sure I must have used WordPad at some point, or more likely it’s direct predecessor (Write). I used to use that kind of stuff a lot until I graduated to just using plain text editors like Notepad++ and BBEdit.
