A drag and drop Editor for free

Hey guys, so my Grandmother has had this website for a long time. The Editor she has been using is now at its EOL, so she needs a new one. I mainly just code myself, so I was wondering if guys know of any free WYSIWYG Editors for windows.

Much like you I mostly deal with code, so I might not be the best person to help. I have, however, used WordPress and it seems to be really good for drag and drop websites. Hope this was helpful in some way!

I would say Squarespace, but that's paid...
