5 Best Free PDF Readers and Viewers for Windows 10 in 20197th March 2019 by Manish Sahay is a good review. Adobe itself is an unpleasant company that writes bad software and has moved its pdf-writing software on line, probably to better rip off customers and harvest their information. Their reader is purposely limited and unsatisfactory and they write poor software anyway. I've tried Foxit and been disappointed for some reason, and PDF-XChange Editor was bad enough for some reason I forget that I decided it wasn't minimally satisfactory. Sumatra is very clean, but requires CTRL-mouse if you want to select text. So i have settled on STDU Viewer, at http://www.stdutility.com/stduviewer.html.

Libreoffice seems to be good. It does a great job of printing *.docx files to *.pdf. It was easy to install and it's freeware, opensource.
PDFEncrypt, a simple little opensource app to put a password on a pdf file.

 Musescore is good freeware.
