I'm indifferent about Wordpad; always surprises me to read people don't regularly use Notepad.

I use it as a clipboard scratchpad. It strips RTF when copying between programs since Windows itself has no built-in way of doing so and you can also use it to clean up whatever you're copying. It loads fast and is minimalist.

Some programs on Windows vomit all over themselves when receiving RTF information, like Teams for example. I also read people use the Address Bar/OMNIBar in browsers, but that may transmit to the search provider.

I also use Notepad++ and VSCode. Notepad remains my favorite clipboard toy because it is so fast and light-weight. I use Notepad++ when I need to use its advanced search/replace and visualization tooling (e.g. View -> Show Symbol -> Show All) and VSCode when I need actual language colorization/structural auto formatting.

PS - Ctrl+Shift+V isn't a Windows feature and never was. It is a Microsoft Office shortcut that only 50% of Microsoft Office even supports (e.g. try it in Outlook). A couple of third party programs support it, but it is incredibly YMMV.
