MS Publisher Alternative that works well with windows 10?

I was dismayed to get my new computer from HP with MS Office loaded to discover that Publisher was not part of the package

I have Office 2016 and discovered that, although I can create posters in MS Word, I cannot save the file as a jpg picture.

Does anyone know of a good free publisher alternative that works well with windows 10? (not scribus, ick)

On my old computer that ran Windows Vista Home Premium (ick again, lol) I had MS Office 2003, which I loved and it had all the apps, but this one does not, sadly and I really really miss Publisher.

Publisher doesn't come with all editions of the various Office suites, usually only the 1 or 2 most costly, but used to be available as a stand-alone. However, it was never free. One I have used for awhile is Serif PagePlus, not free but cheaper than Microsoft offerings. Both programs are pretty much classed as desktop publishing which should help narrow a search for something useful, one example found was Serif's free Starter version.

Hmm, I don't know another...
